Spring-Energized PTFE Seals

KOK supplies spring-energized PTFE seals for demanding sealing environments requiring enhanced chemical resistance, pressure capability, and temperature stability.

These seals consist of a precision-formed PTFE sealing jacket energized by an internal metal spring, providing consistent radial load across varying pressure and temperature conditions.

Functional Advantages

Spring-energized PTFE seals are typically specified for:

• High-pressure hydraulic systems
• Aggressive chemical environments
• Oil & gas applications
• Precision fluid control equipment

The spring mechanism compensates for wear, thermal expansion, and pressure variation, maintaining sealing force throughout service life.

Application Scope

• Oil & gas systems
• Industrial hydraulic equipment
• Chemical processing machinery
• High-performance fluid sealing systems
