O-rings are doughnut-shaped gaskets that help block the free flow of air, gases or fluids. They are utilized on devices such as automotive coolant systems and waterproof camera housings. O-rings are usually made from a flexible synthetic rubber or a thermoplastic polymer. If not properly lubricated, O-rings will dry out and crack, rendering the ring useless.
Things You'll Need
- O-ring lubricant
Inspect the O-ring for pre-existing cracks or tears that may indicate that the ring needs to be replaced.
Place the tip of the lubricant nozzle directly on to the O-ring.
Squeeze the lubricant bottle lightly to apply lubricant to the O-ring.
Repeat Steps Two and Three on the opposite side of the O-ring to ensure that the entire ring is lubricated.
Run your finger around the O-ring to spread the lubricant around it's entire circumference.
Wipe away any excess lubricant with a rag.
Tips & Warnings
- Select a lubricant product that is labeled for use on your particular O-ring.
