New / Old Stock, Brass Swivel Barbs, Hose Tails, 1/4" Female NPT Pipe Threads x .298" OD Barb for ID Hose, with Fiber Gaskets Included. Each bid quantity is for a Lot of Ten (10) Pieces. You may bid / buy any number of lots, up to the total quantity available above.
These were purchased at an industrial liquidation earlier this year, and they came from open bins stored in a dusty industrial environment. Unlike ordinary NPT fittings which seal at the threads, these use a fiber gasket to seal against the end of your 1/4" NPT male pipe nipple. The end of your male nipple should be smooth, however, there is no need to apply thread tape or pipe dope to the threads. Allows your hose to swivel, to prevent kinks when tightening.
