McMaster-Carr offers a variety of push-to-connect tube fittings made from plastic or metal that provide a quick and secure connection for tubing. They feature collet-style grippers that grab onto the tubing when it is inserted and an internal seal that prevents leaks. The fittings come in different sizes to accommodate various tubing diameters. They are available in straight, elbow, tee, cross, and reducer configurations. The fittings can handle pressures up to 250 psi and temperatures up to 200°F. They are ideal for use in pneumatic, cooling, lubrication, and industrial process applications. The push-to-connect design allows tubing to be connected without requiring barbs, clamps or threads.
