The unique design of the 10-32 UNF Swivel Fitting allows the barb to swivel 360° in the threaded base. The 10-32 threads are self-sealing and do not require a gasket. Barbs are available for 1/16", 3/32", and 1/8" I.D. flexible tubing. The snap type fitting is sealed with a Buna-N O'ring; Viton and Ethylene Propylene o'rings are available. The swivels are precision molded of nylon.
