Full Face EPDM PN25 Joints 3mm
The Full Face EPDM PN25 Joint (3mm) is a high performance rubber flange gasket built for demanding pipeline environments. At 3mm thick, the gasket compresses evenly across the full flange face, filling minor surface imperfections and creating a dependable, leak proof seal across the entire contact area. Pre-cut bolt holes ensure precise alignment during installation, reducing setup time and eliminating guesswork on the job site.
Engineered from premium EPDM rubber, this gasket holds its own against water, ozone, UV exposure, and weathering, making it equally suitable for outdoor installations and long-term industrial use. With a Pressure Nominal (PN) rating of 25, it is designed to handle up to 25 bar, giving engineers and contractors confidence across medium-to-high pressure systems.
Whether sealing cold water supply lines, drinking water pipework (WRAS-approved variants available), sewage systems, or general industrial pipework carrying air and diluted acids or alkalis, this gasket performs reliably across a wide range of applications. The full-face design also serves a protective function, shielding metal and plastic flange faces from corrosion and direct contact damage—extending the service life of the surrounding pipework components.
Summary:
- A full face EPDM PN25 3mm joint (or flange gasket) is a 3mm thick rubber seal used between two flanged pipes to stop leaks
- The "full face" design covers the entire flange surface and includes pre-cut bolt holes
- EPDM resists water, ozone, UV rays, and weathering very well
- Pressure Nominal 25. This means it is rated to handle medium-to-high pressure industrial pipe systems (up to 25 bar)
- 3mm: The thickness of the rubber sheet, which helps it compress and fill minor surface gaps on the flanges
Applications:
Common applications include;
- Water systems: Sealing cold water supply lines, drinking water (if WRAS-approved), and sewage or drainage pipes
- Industrial plants: General water, air, and diluted acid or alkaline pipework
- Flange protection: The full-face style helps align bolts during installation and keeps the entire face of the metal or plastic flange protected from corrosion or contact
