description Parker FlexiSeal Overview
The Parker FlexiSeal is a spring-energized polymer seal manufactured by Parker Hannifin for use in demanding mechanical applications. The seal consists of a PTFE or other polymer jacket energized by a metal spring, which maintains contact pressure against sealing surfaces even under low temperatures and varying pressures. It is designed for environments involving extreme temperatures, aggressive chemicals, or high friction, and is used in aerospace, semiconductor, oil and gas, and defense systems.
help Parker FlexiSeal FAQ
What is a Parker FlexiSeal used for?
The Parker FlexiSeal is a spring-energized polymer seal utilized in demanding mechanical applications where traditional elastomer seals fail. It is designed to maintain contact pressure against sealing surfaces even under extreme temperature and pressure conditions.
What materials make up the Parker FlexiSeal?
A standard Parker FlexiSeal consists of a polymer jacket, often made of PTFE, which is energized by an internal metal spring. This specific combination of materials allows the seal to withstand aggressive chemicals and friction.
Who manufactures the FlexiSeal?
The FlexiSeal is manufactured by Parker Hannifin, a global leader in motion and control technologies. They offer various configurations of the seal, including different spring types and polymer blends tailored for specific industrial applications.
How does the metal spring in a FlexiSeal work?
The metal spring provides a constant outward radial force, ensuring the polymer jacket stays in tight contact with the sealing hardware. This resilient force compensates for hardware wear, thermal contraction, and pressure changes that might otherwise cause a leak.
