BIRNS wrenches permit easy installation of BRs, ORs, and retention jam nuts; and facilitate loosening of tight coupling rings*.
*Wrenches should not be used to tighten coupling rings, only to loosen. Please note: BIRNS minimum order is $300.
The CP face O-ring installation tool is custom-designed (and specifically sized for each CP) to allow fast and easy O-ring installation into the CP’s quarter-dovetail groove without damage to the O-ring or connector.
