2.5 MPaBoosted supply · pump station outlets
4.0 MPaIndustrial water · chemical plants
6.0 MPaHigh-pressure water · mine backfill
10 MPaOil & gas lines · pipeline repair
15 MPaHigh-pressure injection · test lines
20 MPaSpecial engineering · project-designed
03 · Seal Compounds
The Right Seal For The Media
Seal choice decides the clamp's real-world envelope. Compare the five compounds we build with.
| Seal | Temperature | Media Resistance | Best For |
|---|---|---|---|
| EPDM | -40°C ~ +130°C | Water · steam · mild acids/alkalis · ozone | Municipal water, wastewater (standard) |
| NBR (nitrile) | -30°C ~ +100°C | Mineral oil · fuel · lubricants | Petroleum, hydraulic, fuel lines |
| FKM bonded / fluoroplastic-coated | -20°C ~ +200°C | Strong acids · alkalis · solvents · chlorides | Chemical, plating, acid/alkali lines |
| Silicone (VMQ) | -60°C ~ +200°C | High-temp steam · hot oil · mild media | Steam and hot process lines |
| PTFE | -100°C ~ +200°C | Nearly all media · cryogenic | LNG, liquid nitrogen, ultra-low temp |
