Application-
Quick release couplings solve the problem of quick connection and disconnection of flexible hose assemblies. The connection can be made faster and easier than in the case of standard screwed couplings (threaded, flanged) because it is made by hand, with no tools. Usually, it requires only pushing a plug into a socket. Locking occurs automatically, using the spring mechanism.
Construction-
Each coupling consists of a coupler and adaptor with or without NRV (non-release valve).
