Product Introduction
Permabond® A131 is a high-performance anaerobic adhesive that effectively seals threaded metal pipe connections carrying a variety of gases and liquids, including potable water. The delayed cure feature allows for accurate alignment of components, and it provides an instant low-pressure seal without drying out like many mastics, eliminating rework. Disassembly can be done with regular tools.
PERMABOND® A131 Features
- Allows alignment during curing
- No loose particles to clog valves
- Instant low-pressure seal
- Excellent chemical resistance
- KIWA approved for hydrogen, drinking water, and Gastec QA
- WRAS listed for potable water
PERMABOND® A131 Applications
- Sealing threaded metal pipe connections
- Suitable for use in hydrogen and drinking water pipelines
