Vintage Triumph Gaskets and Seals
Keep your classic Triumph motorcycle running like the day it left the factory with our comprehensive selection of authentic gaskets and seals. Whether you’re rebuilding that legendary parallel-twin or triple engine, or just freshening up the top end, we have the high-quality components you need.
Prevent leaks and ensure a proper seal with our huge inventory of genuine Triumph gaskets. From cylinder base gaskets to valve cover gaskets, we carry gaskets for every application on vintage Triumph twins and triples. Made from premium materials like copper and aramid fiber to meet original specifications.
We also stock oil seals, O-rings, and other seals to keep your Triumph’s oiling system working properly. Crankshaft seals, countershaft seals, fork seals and more are available for models like the Bonneville, Trident, and Trophy.
