PEEK Back Up Ring

PEEK Back Up Rings provide superior support for O-rings in high-pressure and high-temperature environments.

What is a PEEK Back Up Ring?

A PEEK (Polyether Ether Ketone) Back Up Ring is a high-performance support ring designed to reinforce O-rings in dynamic or static sealing applications, especially under high pressure or extreme temperatures.

Key Features:

Made of durable PEEK material for excellent wear and chemical resistance

Prevents O-ring extrusion in high-pressure environments

Compatible with most elastomer materials (NBR, FKM, PU, etc.)

Suitable for dynamic and static sealing applications

High temperature and pressure tolerance

why Choose PEEK Back Up Rings

Extends the service life of O-rings

Prevents extrusion and seal failure under high pressure

Reduces maintenance costs and downtime

Chemical and temperature resistant

Installation Guide

Tip: Always use the correct size to avoid extrusion or misalignment.

Inspect groove and O-ring

Ensure proper dimensions and cleanliness.

Position Back Up Ring correctly

Place behind the O-ring, aligned with the groove.

Lubricate (if necessary)

Use compatible lubricant for smooth installation.
