This Pneumatic quick coupling are the original Tru-Flate design. Sleeve type couplings are widely used to connect air lines and can also be used with low pressure fluids.Their compact and economical design uses a ball locking mechanism consisting of captive steel balls that engage the locking groove on the mating nipple. The sliding spring loaded sleeve on the coupler must be manually retracted in order to connect or disconnect the nipple. It is easy to do, but two hands are normally required.Common applications include: compressed air, water, grease,paint, limited vacuum and limited gases.
