How can we improve?

16,830 Products

Most Likely Products

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Bumpers

Absorb impact to protect equipment and surfaces from dents and scuffs

O-Ring Cord Stock

O-Ring Cord Stock

Cut to length to create customized seals

O-Rings

Fit snugly into a groove between parts to create a leak-resistant seal

O-Rings

Fit snugly into a groove between parts to create a leak-resistant seal

Backup Rings

Extend the life of O-rings and improve their performance under high pressure

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

Tube Fitting Gaskets

Tube Fitting Gaskets

Prevent leaks when connecting sanitary tube fittings

Hose Washers

Place inside nozzles and spigots to prevent leaks in an attached hose

Pipe Gaskets

Form tight seals when connecting flanged pipe fittings

Drain Gaskets

Create a watertight seal between your drain and fixture without the mess of plumber's putty

Gauge Glass Gaskets

Gauge Glass Gaskets

Seal the glass on level indicators to monitor liquids without leaks

Manway Gaskets

Create a tight seal between the nozzle and lid of tank car manways

Drum-Plug Gaskets

Drum-Plug Gaskets

Form a tighter seal in drum openings than with a drum plug alone

Gasket Material

Gasket Material

Cut custom shapes and sizes to fill gaps between flat surfaces

Drum Gaskets

Seal lids onto steel and stainless steel drums

Made-to-Order Gaskets

Made-to-Order Gaskets

Send your exact specifications to get gaskets that fit precisely between surfaces
