Quick Release Coupling

Quick couplings are the ideal solution if you need to connect and disconnect pressurized fluid lines quickly and without spilling a single drop.

They are used in applications where a fluid line must be connected or disconnected constantly and quickly. 

Redfluid manufactures the plugs according to the ISO 7241 standard; the ISO 7241 standard says they must be safe, easy to use, and reliable.

Redfluid plugs have valves on both sides of the plug to avoid spilling any fluid. They are available in 316 stainless steel and BSP or NPT thread.
