Silicone O-Ring Set – 351 Pieces, Heat & Oil Resistant

Stop leaking pipes and failing seals in their tracks with our comprehensive silicone o-ring set. This massive 351-piece assortment kit provides everything you need to repair, maintain, and upgrade seals across your home, vehicle, and workshop.

Whether you are fixing a leaky faucet, rebuilding a carburetor, or maintaining industrial pipelines, this silicone o-ring set is the ultimate all-in-one solution. Crafted from premium-grade materials, these seals are designed to withstand extreme conditions without degrading.

Why Choose This Silicone O-Ring Set?

Standard rubber O-rings crack, dry out, and fail when exposed to heat, oil, or harsh chemicals. Our advanced silicone o-ring set is specifically engineered to resist these elements, ensuring a long-lasting, watertight, and airtight seal every time.

Instead of running to the hardware store for a single size, this kit gives you 10 of the most commonly used metric sizes right at your fingertips. Having a silicone o-ring set on hand saves you time, money, and the frustration of mid-repair trips to the store.

How to Choose the Right Size

To ensure a perfect seal, measure the inner diameter (ID) and cross-section (thickness) of your old, worn-out O-ring. Match these measurements to the size chart included with your silicone o-ring set. When in doubt, sizing up slightly is often better than sizing down, as silicone has excellent compression properties.
