10-Pack M6 M8 Rubber Seal Gaskets for Toilet Seat Bolts

Stop Leaks & Keep Toilet Seats Firmly in Place

Tired of loose toilet seats or slow drips around the water tank? These 10-piece non-slip rubber seal gaskets are designed to create a secure, watertight seal around M6 and M8 toilet bolts. Made from durable, flexible rubber, they compress evenly to lock out moisture and prevent fittings from working loose over time — no special tools required.

Frequently Asked Questions

Q: What sizes are included in this rubber seal gasket pack?

A: The pack contains 10 rubber seal gaskets covering two standard bolt sizes: M6 (inner diameter 6 mm, overall size 25 × 10 mm) and M8 (inner diameter 8 mm, overall size 27 × 7 mm). Both sizes are commonly used on toilet seat bolts and water tank fittings.

Q: Can these rubber gaskets be used for purposes other than toilet seats?

A: Yes! While they are specifically designed for toilet seat bolts and water tank screws, they are compatible with any bolt or fitting that requires a sealing washer of the same M6 or M8 dimension — including general plumbing fixtures, bathroom hardware, and other household fittings where a watertight seal is needed.

Q: How do I know if I need to replace my toilet seal gasket?

A: Common signs that a gasket needs replacing include visible water drips around bolt areas, a loose or wobbly toilet seat that won't stay tight even after tightening the bolts, or visible cracking and hardening of the existing rubber washer. Replacing worn gaskets promptly helps maintain a secure fit and prevents water damage.

Q: Are these gaskets easy to install without professional help?

A: Absolutely. Installation is a straightforward DIY task — simply remove the old gasket from the bolt, slide the new rubber seal into position, and reassemble the fitting. No special tools or plumbing experience is required.
