PTFE Piston Rings

Maintenance free, low friction,
Self lubricating PTFE Piston Rings

PTFE Piston Rings

Beldam Crossley PTFE Piston Rings are suitable for all dry-running applications and are constantly being developed to deliver better results.

Using Beldam Crossley piston rings helps to reduce the operating costs of the machine and allow environmental legislation to be fully complied to much easier.

Beldam Crossley provides a design service for our PTFE products which means we can engineer the correct solution to your requirements without having to sacrifice quality.

Our design team have spent hundreds, if not thousands of hours developing bespoke, high-quality PTFE products and take the time to understand your requirements to design you a product that works 100%.

The advantages of using Beldam Crossley PTFE Piston Rings are:

Piston Rings Advantages

Cord seal (also known as rope seal)
offers designers and engineers the ability
to increase operating efficiencies by
reducing hot gas leakage between
components in aircraft engines, other
turbines and high temperature static

Slide Wire & Textile Overbraid Wire & Textile Overbraid Overbraid provides reinforcement and
protection from mechanical and abrasive
damage, in addition to external chemical
attack to all types of rubber and plastic
tubing. In addition, overbraid can be used
for protecting both metallic & PTFE bellows.
It also increases the hoop strength of the
tubing and limits axial movement.
