Guide to choosing industrial fittings: everything you need to know Choosing the right fitting is a crucial step in the design and maintenance of any industrial plant. From compatibility with the fluid being handled to mechanical and environmental stresses, every detail affects the efficiency, durability and safety of the system. In this article, we guide you through the selection of industrial fittings, providing you with a clear and practical overview of the criteria to consider and the most effective solutions. Whether you are designing a new plant or upgrading an existing system, making the right choice means reducing risks and optimising costs in the long term. Materials, shapes, performance: how to choose the right fitting Every industrial application has specific requirements that influence the choice of the most suitable fitting. Here are the main factors to consider: 1. Fluid type and chemical compatibility The fitting material must be compatible with the fluid being handled (liquid, gas or corrosive substances). Technopolymer fittings, for example, are ideal for aggressive fluids or environments where corrosion must be avoided. 2. Operating temperature and pressure Operating conditions are crucial: high-temperature or high-pressure systems require resistant materials and advanced technical specifications. In these cases, metal or reinforced technopolymer fittings are often considered. 3. Type of system and mechanical stress If the system is subject to vibrations, dynamic loads or frequent variations, it is necessary to choose fittings that can guarantee tightness, flexibility and long life. 4. Regulations and certifications Regulated sectors (food, pharmaceutical, chemical) require fittings that comply with specific safety and hygiene standards. Bucchi offers industrial fittings with certifications that meet the highest international requirements. Shapes, threads and configurations: adapting the fitting to the system Another decisive factor in choosing the right fitting is its technical configuration. The shapes, threads and joining systems must meet the exact requirements of the system to ensure a secure, durable and easily inspectable connection (even in the case of preventive maintenance of the fittings). The most common configurations include: • Straight fittings: ideal for linear connections between two pipes or components with the same axis. Available with different combinations of male/female threads or push-fit connections. • Elbow fittings (90° and 45°): allow the direction of flow within the system to be changed, maintaining optimal sealing and fluid dynamics. • T or cross fittings: used to create multiple branches in circuits, they are essential in complex systems with multiple distribution lines. • Quick-connect and plug-in joints: designed to simplify installation and maintenance, they reduce assembly times and improve ergonomics. • BSP, NPT, GAS or metric threads: compatibility with international standards is essential to ensure interchangeability and safety in connections. The availability of such a wide range of configurations allows each fitting to be adapted to complex systems or confined spaces, optimising performance and simplifying maintenance. With Bucchi's technical support, each customer can identify the ideal solution based on the system layout and application specifications.

When designing industrial, agricultural or original equipment systems, the choice of fittings is key to ensuring efficiency, safety and durability. One of the most strategic decisions concerns the material: are polymers or metal fittings better? Both solutions have advantages and critical issues, but what really makes the difference is the correct assessment of the specific needs of the application. In this article, we explore the main features of each option to help you make an informed choice, thanks also to the technical support of a reliable partner such as Bucchi. Polymers fittings: lightness, chemical resistance and customisation Polymers fittings, or more precisely technopolymer fittings, are now a high-performance solution for many industrial sectors. Their success is due to a combination of technical and economic factors that make them ideal for a wide range of applications. Here are four advantages of technopolymer fittings: 1. Lightweight and easy to install Technopolymer fittings are lightweight, which makes them easy to transport, handle and install, even in complex systems or areas that are difficult to access. This reduces operating times and costs. 2. Excellent chemical resistance Technopolymers such as polypropylene (PP), nylon PA66 or acetyl resin (POM) offer high resistance to corrosion and aggressive fluids such as solvents, acids or fertilisers. This makes them particularly suitable for the chemical, agricultural and food industries. 3. Versatility and customisation options Thanks to advanced production processes, technopolymer fittings can be made to measure, with customised geometries and technical specifications based on the application. Bucchi, for example, develops specific solutions for complex systems or extreme operating conditions, supporting customers with co-design and application testing services. 4. Competitive cost and durability Compared to metal, plastic often has a lower cost, especially when considering the product's life cycle. This is important because durability in corrosive environments and reduced maintenance requirements contribute to significant long-term savings. Metal fittings: mechanical strength and application limits Metal fittings have always been a popular choice in many industrial applications, especially where high mechanical performance is required. However, their use also has certain limitations, particularly in terms of weight, chemical resistance and design flexibility. Let's take a look at them together: 1. High mechanical and thermal resistanceThe main strength of metal fittings is their robustness, which makes them ideal for high-pressure or high-temperature systems where very high structural resistance is required. Materials such as stainless steel, brass or aluminium guarantee reliable performance in extreme conditions. 2. Greater weight and installation complexityHowever, the weight of metal fittings compared to technopolymer fittings can be a problem, especially in systems where lightness is an operational advantage. In addition, these fittings often require specific tools and greater attention during assembly, resulting in increased installation time and costs. 3. Susceptibility to corrosionAlthough some metals are treated or naturally resistant to corrosion, exposure to certain chemicals or environmental agents can compromise the durability of the fitting. In sectors where chemical compatibility is essential, plastic can be a safer and more reliable option. 4. Limited design flexibilityMetal processing involves constraints in the creation of complex shapes or customised solutions. In contrast, engineering polymers allow greater design freedom, facilitating the development of complex geometries and fully customised solutions. Polymers or metal fittings? Applications that make the difference The choice between plastic or metal fittings depends heavily on the application context and specific operating conditions. Each material clearly has characteristics that make it more suitable for certain uses, and knowing these differences is essential to ensure efficiency, durability and safety. Therefore, a thorough understanding of the context of use is key to making the right choice: each application has specific requirements, and only a careful technical analysis can guide you towards the ideal fitting. When to choose technopolymer fittings Technopolymer fittings are the ideal solution in all contexts where lightness, chemical resistance and ease of installation represent a competitive advantage:• Corrosive fluid treatment plants: plastic materials offer superior chemical compatibility compared to metals.• Agriculture and irrigation: lightness, ease of maintenance and resistance to atmospheric agents make them perfect for this type of application.• Environments with a risk of metal corrosion: saline, humid environments or those with aggressive substances require materials that do not oxidise or deteriorate over time When to choose metal fittings Metal fittings are suitable for high-load applications or in extreme environments where mechanical properties must be at the highest level:• High-pressure or high-temperature systems: here, the strength and thermal stability of metal are essential.• Oil & gas sector: the highly technical and regulated environment requires superior, certified components.• Automotive and heavy industry: structural strength and durability make metal the most reliable choice. Final thoughts: the right choice starts with your needs and your partner Choosing between plastic or metal fittings is never an absolute decision, but a technical assessment that must consider numerous factors such as the type of fluid, operating conditions, mechanical and environmental stresses.

Plumbing: how to choose the right fittings for an evergreen garden Whether it is a small green space or a large garden, a well-designed irrigation system makes all the difference in terms of plant health, water saving and practicality. In this article we find out how best to achieve this, with a specific focus on the importance of correctly choosing both the plumbing fittings and the technical components: because even the details count, especially when it comes to quality and durability. How an irrigation system works and why the quality of plastic fittings is fundamental A garden irrigation system is composed of a series of elements that work in synergy to guarantee an even and controlled distribution of water. From the programming unit to the hoses, from drippers to sprinklers, each component has a specific role. But there is one element that is often underestimated, and which has a decisive influence on the functionality of the entire system: the hydraulic fittings. The fittings for an irrigation system are nothing more than connection solutions, i.e. they are the connection points between the various parts of the system. They obviously perform a very specific function: to ensure that water is conveyed correctly, without leaks, with the right pressure and with a stable seal over time. If they are not made of quality materials or if they are not designed to withstand the stresses of the outdoor environment, these fittings can become the weak point of the system. Leaks, accidental disconnections or breakages are in fact among the most common problems with the wrong choice of irrigation system fittings. Furthermore, in a context such as gardening, plumbing fittings are often exposed to challenging environmental factors: UV rays, temperature changes, humidity, varying pressure and possible shocks. For this reason, it is essential to choose connection solutions specifically designed for irrigation systems that ensure durability, stability and ease of installation. The quality of thermoplastic fittings for conveying fluids is, therefore, one of the keys to an efficient and durable irrigation system. This is why professionals and installers rely on advanced technical solutions such as those proposed by Bucchi, a company specialising in plastic hydraulic fittings, designed to offer high performance even in the most challenging outdoor contexts.
