PTFE Seals

MADE IN THE USA

High-Performance PTFE Seals for Extreme Chemical and Thermal Environments

Kelco Industries engineers and manufactures precision PTFE seals designed for superior performance in demanding applications where standard elastomers fail. Our seals provide exceptional chemical resistance, low friction, and dimensional stability across wide temperature ranges, making them ideal for dynamic and static sealing in aerospace, chemical processing, energy, and industrial systems.

Available in virgin, filled, and custom PTFE formulations, each seal is manufactured to exacting tolerances to ensure leak-free performance, reduced wear, and extended service life—even under high pressure, aggressive media, and thermal cycling.

Kelco’s PTFE sealing solutions are proudly made in the USA and offered in standard and custom geometries, including rotary, reciprocating, and static designs—tailored to meet AS9100 and ISO 9001 quality standards for mission-critical reliability.
