GREASE NIPPLE HANDY PACK

Grease nipples (also known as Zerk fittings) are small metal "gateways" used to inject lubricant directly into mechanical parts. They are essential for parts that move, rotate, or pivot, as they allow for maintenance without needing to take the entire machine apart.

Key Uses and Functions

Precision Lubrication: They provide a direct path for a grease gun to force lubricant under pressure into internal areas like bearings, bushings, and joints.
Contamination Barrier: Most nipples contain a spring-loaded ball bearing that acts as a one-way check valve. This allows grease in but seals shut when the pressure stops, keeping out dirt, water, and debris.
Friction & Wear Reduction: By ensuring moving parts stay well-lubricated, they prevent metal-to-metal contact, which reduces heat and extends the lifespan of machinery.
Accessibility: Angled versions (45° or 90°) allow you to reach lubrication points in tight spaces or behind other components where a straight nozzle won't fit.

Common Applications

Automotive: Steering linkages, suspension ball joints, and U-joints on drive shafts.
Agriculture & Construction: Earthmoving equipment, tractor pivots, and conveyor systems.
Industrial: Factory machinery, pumps, and motors that require frequent regreasing.
