Sealing

Gasket Material

Gasket Material

Cut custom shapes and sizes to fill gaps between flat surfaces

Gasket Tape

Stick in place around doors, enclosures, and vents to create a leak-resistant seal

EMI/RFI Shielding Gaskets

EMI/RFI Shielding Gaskets

Raw Materials

Foam

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

Rubber

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

Felt

Thicker and more absorbent than fabric for insulating, polishing, cushioning, and gasketing

Mica

An electrical insulator that resists high temperatures; use in circuit breakers and heating elements

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Carbon

An electrical conductor that’s often used in electronics and sensors

Building and Machinery Hardware

Grommets

Protect wire, cable, and cords from holes with sharp or rough edges
