Raw Materials

Multipurpose Blended Neoprene Foam Tubes

Neoprene is blended with EPDM and polyethylene for foam tubes that offer good resistance to water, sunlight, and oxidation.

Ultra-Weather-Resistant EPDM Foam Tubes

These EPDM foam tubes have the best resistance to water, sunlight, and oxidation of all the foam tubes we offer.

High-Temperature Foam Tubes

Multipurpose Neoprene Rubber Tubes

Jackets, seals, and insulation are just a few of the many uses for rubber tubes.

Weather-Resistant EPDM Rubber Tubes

Used to seal narrow spaces such as channels, these tubes offer more compression than solid EPDM rods.

Nonporous Alumina Ceramic Multiple-Bore Tubes

Nonporous Alumina Ceramic Tubes

Thermally Shock-Resistant Mullite Ceramic Tubes

Protectively sheath materials, such as thermocouples, that move between hot and cold environments. Similar to nonporous alumina tubes, air and gas cannot pass through these mullite tubes.

Extra Thermally Shock-Resistant
Single-Closed-End SiAlON Ceramic Tubes

Often used as a protective shield in thermocouples and other conditions with drastic climate changes, these SiAlON ceramic tubes won't deform, expand, or crack when repeatedly exposed to large temperature changes.
