Standard Ring Spacer
Standard Ring Spacer
Standard Ring Spacers are precision-cut thermoplastic rings designed to fit between two flanges while allowing full flow. They provide dielectric isolation, thermal breaks, and corrosion protection, making them ideal for non-blocking, insulated applications.
- Polypropylene (PP) – Cost-effective and lightweight
- PTFE (Teflon®) – Exceptional chemical and temperature resistance
- PVDF (Kynar®) – Flame resistant and UV stable with broad chemical compatibility
All sizes and thicknesses are listed in inches.
Our specs are for lined pipe dimensions. Any spacer can be customized to your specifications.
