In Focus: LockNLube Grease Coupler

June 5, 2017
The LockNLube Grease Coupler can make greasing faster, easier and cleaner.

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.

Application

The LockNLube Grease Coupler can make greasing faster, easier and cleaner regardless of the class or type of machinery, according to the company. 

Selling points

  • Compatible with all grease guns, helping to improve their functionality, regardless of brand, make or model. 
  • Compact design doesn't take up much space on the truck and can be sold easily to a variety of customers. 
  • Comes with a one-year warranty and a 30-day money-back guarantee. 

Features and benefits

  • Leak-free seal with hardened steel jaws that lock onto the grease fitting and will not pop off under pressure. 
  • Technician has both hands free to operate the grease gun. 
  • Reduces the cost and cleanup of wasted grease. 
  • Rebuildable, so if the seal wears out, the seal and jaws can easily be replaced. 

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. 

Manufacturing specs

The Grease Coupler is still manufactured by the inventor in South Africa.

  • Four hardened steel jaws and a long-lasting nitrile rubber seal.
  • Effective up to 10,000 psi
  • Weighs 4 oz
  • 3.5" long. 

Storage and display

The LockNLube Grease Coupler ships in boxes of 20. The boxes are 9" width by 8" depth by 4" height. For demonstrations, LockNLube suggests using their countertop display unit, which features a 20" grease hose, LockNLube Grease Coupler, a regular and recessed grease fitting and two hooks to display 10 grease couplers. This allows customers to try the coupler on various fittings before they buy.
