Grease Nipple Caps
FlagshipRushabh's highest-volume, most-trusted product line. A precision-moulded PVC cap that seals over the grease nipple between service intervals, keeping dirt, dust, and moisture out of the ball-check seat and extending the working life of every fitting it protects. Moulded with an integrated pull-tab for fast, tool-free removal.
PVC Cap
Precision-moulded PVC push-fit seal with an integrated pull-tab for fast, one-handed removal. Easy to fit and remove at frequent service points without tools, and built to outlast rubber in oil, grease, and UV exposure.
Application
Fitted over grease nipples in maintenance-heavy environments to prevent contamination ingress during storage, transit, and between lubrication cycles. High-visibility red PVC finish makes a missing cap immediately obvious during inspection.
Why we build it in PVC
We standardised this cap on PVC (polyvinyl chloride) rather than natural rubber, for reasons that matter to a buyer running thousands of these in the field.
PVC resists oil, grease, and a wide range of industrial chemicals without swelling or perishing, so the cap does not degrade from contact with the very lubricant it protects. It also holds its colour and flexibility across long outdoor exposure, where natural rubber tends to crack and stiffen with age and UV.
It moulds to a tighter, more consistent tolerance at high volume, and holds a high-visibility red finish permanently, so a missing cap is obvious on inspection. The result costs less to manufacture at scale without giving up sealing performance, which is why it has become our flagship line.

Precision, in Practice
Each cap is moulded to a consistent internal bore so it seats securely across its full thread-size range. A loose cap that falls off in transit defeats the purpose entirely.
