Reducing Ring Spacer
Reducing Ring Spacer
Reducing Ring Spacers are machined thermoplastic rings designed to transition between two different pipe sizes while maintaining a full open bore. Ideal for systems that require diameter reduction without disrupting flow or flange alignment.
- 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.
