The SPEEDAIRE - 30E546 is a quick connect hose coupling designed for rapid, tool-free connection and disconnection of hoses or equipment using an industrial interchange coupling system. It is a female quick-connect coupling intended to be installed at the end of a hose or at a tool inlet in a pneumatic or fluid line connection. Manufactured from 304 stainless steel with a plain finish, it does not include a valve and features a sealing element made of Buna-N. The coupling accommodates a 1/4 in size quick connect air coupling and connects to hoses with a nominal 3/8 in fitting size via a 3/8"-18 threaded NPT connection. It operates within a temperature range of -40°F to 150°F and supports a maximum flow rate of 1,132.67 liters per minute at a working pressure up to 300 psi.
