Gaskets

Gaskets — New & Used

Gaskets are sealing materials placed between joining surfaces to prevent leaks of fluids, gases or air. They are used in pumps, engines, flanges, valves, housings, and pipe connections — ensuring tight, leak-proof joints across hydraulic, pneumatic, plumbing, and industrial systems.

At Surplus Select, we offer a range of new and used OEM gaskets: flange gaskets, O-ring sets, sheet gaskets, custom cut seals, and housing gaskets. Our surplus pricing helps maintenance crews, repair shops, and OEMs source sealing materials affordably — ideal for rebuilds, overhauls, or preventive maintenance.

Price Match — We match any authorized distributor on identical in-stock parts, so you can buy gaskets at surplus pricing with confidence.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the sealing solutions you need.

Fast U.S. Shipping — Most orders ship same or next business day to help keep your maintenance or production running smoothly.

Find Your Gasket Fast (Search-First)

Search by part number or gasket type (e.g., flange gasket 4 " 150 lb, sheet gasket 1/8" NBR, housing gasket set).
No part number? Try specs like “rubber sheet gasket 2 mm”, “metal-lined flange gasket 6 "”, or “O-ring set for pump”.
Need specific features? Add material (NBR, Viton, graphite), thickness, inner/outer diameter or pressure/temperature rating to refine your search.
