3/8″ BSP male thread high pressure coupler is used widely in Industrial applications. This particular coupler has NBR seal in it for normal operational use. We do have available a different version of this coupler for Motorsport applications (see product code RDP20500021R).

This coupler does not use a standard style of valve, its unique valve system allows for full flow through the coupler without restrictions. This ensures your tool or product gets the maximum amount of air it needs – making sure it does perform to its intended level!

Also it is safer than any other coupler as it has a solid safety locking mechanism and also purges the line before the coupler can be disconnected – eliminating any risk of hose “whip” during disconnection. The coupler features a cover over the top of the coupler to protect it and it also serves to eliminate risk of injury from the purging of the line.
