Manufactured with heat treated steel designed to withstand high pressures without deformation. Fitted with 1/8"BSPT female thread which enables this coupler to be used with multiple pieces of grease equipment, including manual grease guns, air grease guns, electric grease guns and bulk bucket greasers. Ingenious design enables this coupler to firmly latch onto the grease fitting enabling hands-free operation compared to standard grease couplers, meaning less wasted grease around the fitting. Fitted with a quick connect/disconnect lever which enables unit to be disconnected easily with up to 8000psi of pressure. Eliminates the issue of disconnecting a standard coupler from a pressurised condition, which often leads to broken fittings and damaged coupler jaws.
