Selection and Usage Notes
- Guide rings prevent metal-to-metal contact and extend seal life.
- Fabric-reinforced rings suit high loads; PTFE-based strips suit low-friction applications.
- Strips are cut to length; leave a small gap between the ends for thermal expansion.
Frequently Asked Questions
What is the difference between a guide ring and a seal?

How do I order guide strip?
By strip width, thickness, material and the total length needed.
