This Legris 9405U series nylon coated, nickel-plated brass industrial interchange quick connect coupler has a male NPTF threaded end, NBR O-ring, and connects hose to an industrial interchange quick-acting plug. The male National Pipe Thread Taper (NPT) threads connect with female NPT threads for a tighter seal than straight threads. Nickel-plated brass provides corrosion resistance, ductility at high temperatures, and low magnetic permeability, nylon provides lightweight, resistance to abrasion, crushing, and cracking, and the nitrile butadiene rubber (NBR) O-ring provides high tensile strength and resistance to abrasion, tear, and compression set. This fitting has a maximum working pressure of 232 pounds per square inch (psi) (16 bar, 2MPa) with a temperature range of -4 to +140 degrees F (-20 to +60 degrees C, +253 to +333 degrees K) and a flow of 44 standard cubic feet per minute (scfm). It complies with Internal Organization for Standardization (ISO) standard 4414 and European Standard EN983 for quality assurance. This coupler is used in low-pressure pneumatic equipment and air tools in industrial operations.

Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. Hose fittings have various types of connections, including threaded, barbed, push-to-connect, dry disconnect, and others including those based on internationally-accepted specifications. Hose fittings are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.
