Brass Low-Pressure Barbed Tube Fittings for Air and Water
Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings. Use them for low-pressure HVAC systems, drain lines, and other fluid transfer applications, as well as air lines where water vapor and condensate form. The barbs tightly grip tubing for a secure hold. For the best grip, make sure your tubing is squarely cut.
UN/UNF (SAE Straight) male threads with gasket provide extra protection against leaks. Also known as O-ring boss threads.
