For projects requiring secure air-tight seals and extreme anti-leak capabilities, we recommend our internal joint seals. Constructed of highly durable ethylene propylene diene monomer (EPDM) rubber and stainless steel, these seals are designed to function reliably in the most hostile pipeline environments. Custom designed to accommodate pipeline widths of 16 inches and up, they prevent the problems caused by water attempting to enter or exit subsurface structures.

Manufactured according to demanding ANSI/NSF 61 specifications, these seals also meet the rigorous requirements of the ISO 9000 quality standards. Functioning as a permanent solution to the problem of leaks and the debilitating damage they cause, these seals offer outstanding long-term performance. They also offer a wide range of installations and applications. The trenchless installation method saves time and money, increasing the exceptional value provided by our internal joint seals.
