Unmatched Chemical and Environmental Resistance

PTFE Back Up Rings excel in providing consistent sealing under harsh conditions, exhibiting excellent resistance to chemicals, UV rays, and ozone. The non-stick, smooth surface finish minimizes friction and wear, ensuring longevity even in aggressive media and demanding temperatures from -200C to +260C.

Tailored to Your Specifications

We offer fully customizable PTFE Back Up Rings tailored to your drawing, size, and thickness requirements (typically 1-5 mm). Whether you are a manufacturer, distributor, or exporter, our rings are made to fit various profiles and applications with a strict tolerance of 0.05 mm for precise sealing performance.

Superior Physical and Electrical Properties

Engineered with a friction coefficient of just 0.04-0.10 and dielectric strength above 60 kV/mm, these rings deliver exceptional performance in both static and dynamic sealing applications. They are characterized by a tensile strength of 12-25 MPa and maintain their properties throughout extended shelf life and thermal cycling.

FAQ's of PTFE Back Up Ring:

Q: How are PTFE Back Up Rings used in hydraulic and pneumatic systems?

A: PTFE Back Up Rings are installed alongside O-rings in grooves where pressure is high to prevent extrusion of the softer O-ring. This configuration ensures leak-free operation and extends O-ring lifespan in both static and dynamic sealing conditions.

Q: What customization options are available for these PTFE Back Up Rings?

A: We provide custom manufacturing for PTFE Back Up Rings, adjusting thickness (typically 1-5 mm), width, profile, and diameter according to your specific drawing or application. This ensures precise fit and optimal performance in your system.

Q: When should I choose a PTFE Back Up Ring over elastomeric rings?

A: Opt for PTFE Back Up Rings when operating in environments with aggressive chemicals, high temperatures (-200C to +260C), or where exceptional wear, UV, and ozone resistance is required. PTFE's inertness and stability outperform typical elastomeric materials under such conditions.

Q: Where can these PTFE Back Up Rings be applied?

A: They are widely used in hydraulic and pneumatic machinery, process industries, and food-contact equipment (with FDA grades). Their excellent resistance makes them suitable for sealing in challenging chemical, weather, and high-wear environments.

Q: What is the process for ordering food-safe PTFE Back Up Rings?

A: To order FDA-compliant food-grade PTFE Back Up Rings, specify this requirement when requesting a quote or placing your order. We will manufacture the rings using certified PTFE resin and provide compliance documentation as needed.

Q: What are the benefits of using PTFE Back Up Rings in sealing applications?

A: PTFE Back Up Rings provide a virtually unlimited shelf life, low friction, high chemical and weather resistance, self-extinguishing flame resistance, and no tendency to absorb water. These features contribute to long service life and reliable system sealing performance.
