Welcome to NEVALEAK grease fittings, the world’s most advanced grease nipple and grease coupler system, the first and only to utilize equal pressure technology.
The NEVALEAK coupler does not need a locking mechanism. In fact, there are no moving parts. Our coupler is a precision piece of solid metal, this makes our couplers ultra reliable.
The NEVALEAK grease fittings are designed and manufactured in New Zealand.
The NEVALEAK grease fittings are manufactured from stainless steel and the grease coupler is made from solid brass.
NEVALEAK grease fittings are guaranteed not to leak, jam or wear resulting in less mess, less grease wasted, and more profit.
The NEVALEAK zerk fittings are available in many thread sizes. Please visit our grease fittings shop. You will also find dust caps stocked as well.

It has been a long time since the original 1930s grease nipple and grease coupler were invented, but not a lot of improvements have been made since then.
Today’s traditional grease fittings still suffer from leakage, jamming and wear, fortunately NEVALEAK grease fittings have solved these annoying problems.
Have you ever noticed grease leaking from a mechanical joint you were trying to grease?
The main reason this happens is from wear of the grease coupler or wear of the grease nipple. It is hard to visually inspect the wear since it only takes a very tiny area of wear for grease to leak out and because the pressure is so high, typically up to 10,000 psi, any very small misalignment or leakage path will cause grease to leak.
To make matters worse, most operators do not know if it is the grease nipple or the grease coupler at fault, so what usually happens is operators have no time to investigate and continue with the unsolved problems. By this time, the joint is dry and damaged costing thousands to repair.
The NEVALEAK grease couplers and grease fittings solve these frustrations as our couplers have no jaws or teeth meaning virtually no wear. Plus, the O rings generate a superior seal, also it is impossible for the coupler to jam on.
