The Rectorseal 25431 is a soft-set, slow-drying pipe thread sealant designed for use on threaded pipe connections in plumbing, HVAC, and mechanical piping systems. Supplied in a 1-pint container, it can be pressurized immediately after application on piping up to 2 inches in diameter at pressures up to 100 psi. The slow-cure formulation allows for repositioning of fittings after assembly, making it well suited for tight spaces or assemblies that require fine adjustment before the sealant fully cures. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers.
This sealant is recommended for threaded connections on galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, and fiberglass-reinforced PVC pipe. It is appropriate for residential and light commercial piping systems where a flexible, repositionable thread compound is preferred over anaerobic or hard-set alternatives. Typical applications include domestic water supply, gas distribution, and mechanical piping where the listed substrate materials are present.
Recommended for use on threaded galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, and fiberglass-reinforced PVC pipe up to 2 inches in diameter.
Apply to clean, dry male threads before assembly. Shut off and depressurize the system before disassembly or rework of any existing threaded joint. Installation should comply with applicable plumbing and mechanical codes, including IPC and IFGC requirements for thread sealant use on gas and water piping. Do not use on systems or substrates not listed on the product label.
