Product Introduction
Permabond® LH056 is a pipe sealant designed for sprinkler systems, including CPVC piping. It forms an instant seal and cures to surpass the burst rating of the pipe. This sealant replaces pipe dope and sealing tapes, providing a reliable seal even if pipes are not fully seated.
PERMABOND® LH056 Features
- Non-aggressive – will not attack CPVC
- Easy to use and apply
- Directional freedom
- Uncured material dissolves in water
- No solvents
- Excellent chemical and temperature resistance
- Cures at room temperature
- Will not shred, tear, or cause blockages
PERMABOND® LH056 Applications
- Sealing sprinkler systems, including CPVC
- Replacing pipe dope and sealing tapes
- Preventing corrosion and vibration loosening
