The Groz HC/11/4/BSP Hydraulic Coupler is a professional 4-jaw standard grease coupler designed to provide a secure and leak-resistant connection between a hand-operated grease gun and compatible grease/zerk fittings. Groz specifically recommends the HC-11 range for hand-operated grease guns and general maintenance applications.

This model features a 1/8-inch BSP connection, four hardened spring-steel jaws, and a spring-loaded ball check valve. The ball check helps retain pressure during lubrication, while the hardened jaws securely grip the grease nipple to help maintain a reliable connection during grease delivery.

The narrow coupler body is particularly useful when working around grease fittings located in restricted or difficult-to-access areas. A milled slot at the end of the coupler allows convenient tightening, connection and disconnection from grease fittings.

With a rated pressure capability of up to 3,000 PSI, the HC/11/4/BSP is suitable for a broad range of routine lubrication and maintenance operations. Groz lists applications including agriculture, construction, industrial, hardware, automotive and DIY use.
