The LockNLube Grease Coupler attaches to 1/8” NPT threads standard on all grease hoses and works on all Zerk fittings. It does not leak and will not pop off under pressure. After greasing, press the thumb lever to release the coupler from the Zerk fitting. Users can then grease their equipment with both hands free to operate a grease gun, and they can do so without the mess or concern associated with leaking grease couplers or couplers releasing under pressure. The LockNLube Grease Coupler is only 1mm larger in diameter, compared to a standard coupler. It releases easily from recessed fittings.

Origin

The LockNLube Grease Coupler was invented by a sugar cane farmer in South Africa who was frustrated by the continuous leaking of other grease couplers, and the issue of grease fittings popping off under pressure. The LockNLube Grease Coupler was invented to improve upon the design of these grease guns.

Storage and display

This allows customers to try the coupler on various fittings before they buy.
