Blind Ring Spacer
Blind Ring Spacer
Blind Ring Spacers, also known as Hockey Pucks, are solid thermoplastic rings without a central bore, designed to fully block flow in a pipeline while aligning with bolt holes. Commonly used during maintenance or system isolation, they ensure a secure seal without interrupting the flange pattern.
- 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.
