About LEGRIS

Legris is a manufacturer of pneumatic and fluid system components, with a product history dating back to the early 20th century. The brand is known for its push-to-connect tube fittings, which allow for rapid assembly and disassembly without tools. Legris products are used in industrial automation, compressed air systems, fluid handling, and various OEM applications. The company's portfolio includes tube fittings, quick exhaust valves, barbed fittings, and other pneumatic accessories. Legris fittings are commonly constructed from nylon 6.6 and nickel-plated brass, offering resistance to corrosion and compatibility with a range of media. The push-to-connect design features a collet and O-ring seal that grips the tube and provides a leak-tight connection. Legris offers fittings in inch and metric sizes, with thread types including NPT and BSPT. Operating pressure ratings vary by product; for example, quick exhaust valves are rated up to 150 psi, while tube fittings typically handle pressures up to 290 psi depending on size and material. Temperature ranges for nylon fittings generally span -20°C to 80°C, with higher limits for brass components. 3G Electric supplies Legris products globally, maintaining a catalog of over 1,900 SKUs. The product range includes push-to-connect fittings (unions, tees, elbows), quick exhaust valves, barbed adapters, and other pneumatic components. 3G Electric provides datasheets, technical specifications, and logistics support for Legris products, serving plant engineers, maintenance managers, and procurement specialists. The company interprets custom demand and offers application support to ensure correct product selection. Legris products are available in various packaging quantities, from single pieces to bulk packs, accommodating both maintenance and production requirements. The brand's fittings are designed for use with tubing made from materials such as nylon, polyurethane, and polyethylene, and are suitable for compressed air, water, and other fluids compatible with the construction materials. 3G Electric's global reach ensures that Legris components can be sourced and delivered to industrial facilities worldwide, with attention to lead times and inventory availability. The product line is complemented by accessories such as tube cutters, release tools, and mounting brackets, though 3G Electric's current catalog focuses on the core fittings and valves. For technical buyers, Legris offers a standardized approach to fluid system assembly, reducing installation time and minimizing leak paths. The push-to-connect mechanism is reusable, allowing for system modifications without replacing fittings. Legris also provides a range of thread adapters and reducers to interface with existing threaded ports. The brand's quick exhaust valves are used to increase actuator speed by venting exhaust air directly to atmosphere, bypassing the directional control valve. These valves are available with port sizes from 1/4 in to 1/2 in NPT, with minimum operating pressures as low as 10 psi. Overall, Legris represents a mature, well-documented line of pneumatic components that 3G Electric distributes with a focus on technical accuracy and supply chain reliability.
