Description

Grease Nipple is a long-thread lubrication fitting with a UNF thread form, used to deliver grease into propshaft universal joints and sliding spline couplings within the drivetrain.

The nipple threads into the joint and accepts a grease gun against its one-way check ball, allowing fresh grease to be charged into the joint while preventing back-flow. The long-thread body suits the deeper fitting bores used on propshaft journals.
