Pneumatic quick-acting couplings

Dry break quick-acting couplings connect without leakage or fluid spray. A double shut-off version (both internal and external ends) seals during connection and disconnection. They are designed for operating pressures to 300 psi and feature a 10-32 thread and are also available with panel mount thread; 5/16-24 UNF. They are available in 303 stainless steel and allow one-hand connection. They minimize dead volume (space between internal and external ends when connected) to eliminate leakage when disconnecting.
