Orifice Ring Spacer
Orifice Ring Spacer
Orifice Ring Spacers are precision-machined thermoplastic components with a centered bore designed for flow measurement and system balancing. Commonly used in conjunction with orifice plates, they allow for accurate differential pressure readings without altering the integrity of the piping system.
- Polypropylene (PP) – Cost-effective and lightweight
- PTFE (Teflon®) – Exceptional chemical and temperature resistance
- PVDF (Kynar®) – Flame resistant and UV stable with broad chemical compatibility
