Grease nipple cap 835/00017A JCB, aftermarket

Grease nipple cap 835/00017A is an aftermarket part for the JCB machines. According to the product card, this part is a grease nipple cap.

A grease nipple is a small valve onto which the grease gun coupler is fitted and through which grease is pumped into a joint, bush or bearing. A spring-loaded ball inside opens when grease is pumped and then closes, stopping grease coming back and dirt getting in. A broken, crushed or blocked nipple will not take grease, so the point stops being lubricated and the pin or bush soon wears. Nipples are therefore checked during greasing and damaged ones are replaced at once.
