When it comes to protecting critical pipeline components, some applications simply refuse to cooperate. Off-center carriers. Large sizing disparities.
That’s where Seal for Life (formerly Raychem) Casing Seals and Flange Seals truly shine.
These aren’t just “wraps.” They’re engineered sealing systems designed to solve real-world field challenges.
Key Advantages:
-
Fiber-reinforced, multi-layer heat shrink backing
-
Integrated fiber mesh layer for enhanced penetration resistance
-
Coated with a very aggressive mastic sealant
-
Works even when the carrier pipe is not centered inside the casing
-
Approximate 66% shrink ratio
That high shrink ratio is critical. It allows the material to conform across a wide range of casing-to-carrier pipe diameter ratios — without sacrificing seal integrity.
The aggressive mastic flows into irregularities, filling voids and creating a durable moisture barrier. The fiber reinforcement provides mechanical strength to resist damage and environmental stress.
The result? A reliable seal in one of the most challenging spots on a pipeline.
