Blind Full Face Spacer
Blind Full Face Spacer
Blind Full Face Spacers are solid thermoplastic discs that fully cover the flange face and bolt pattern, completely blocking flow. They are used for isolating pipeline sections during maintenance, hydrotesting, or system shutdowns, ensuring a reliable seal and no fluid passage.
- 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.
