RectorSeal – No. 5 – Pipe Thread Sealant – 8 fl. oz (237 ml)

General-purpose, soft-setting pipe thread sealant designed to seal and lubricate threaded metal pipe connections in pneumatic, hydraulic, fuel, and general fluid systems. RectorSeal No. 5 forms a reliable, non-hardening seal that allows for easy assembly and disassembly of threaded fittings while preventing leaks under pressure. It is widely used in maintenance and industrial applications where vibration resistance and long-term sealing performance are required.

Application: Threaded pipe fittings in pneumatic systems, hydraulic lines, fuel and oil systems (non-oxygen service), compressed air systems, general industrial and maintenance plumbing connections
Function: Seals threaded joints by filling micro-gaps between metal threads, preventing leakage while lubricating threads for easier tightening and disassembly
