Rectorseal 2144917432 No. 7 Pipe Thread Sealant 1 Pint

Product Description

The RECTORSEAL 2144917432 is a No. 7 pipe thread sealant formulated for use on threaded pipe connections across plumbing, HVAC, and mechanical systems. Supplied in a 1-pint brush-top can, the black-colored compound applies directly to male or female threads using the integrated brush, creating a seal that resists leakage on both low- and high-pressure applications. The flash point of 24.0 degrees C classifies this as a flammable liquid, so storage and handling must follow applicable safety codes. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians and general mechanical contractors also use thread sealants routinely in their work.

No. 7 thread sealant is suited for a broad range of threaded pipe applications including water lines, gas lines, steam lines, and general mechanical piping. The brush-top container allows controlled application on NPT and similar threaded fittings without the need for a separate applicator. It is commonly used in residential and light commercial plumbing systems, as well as in HVAC refrigerant piping and boiler connections where a reliable, leak-free threaded joint is required.

Installation Notes

Application is typically performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the system being serviced. Shut off and depressurize the line before disassembling any threaded joint. Apply the sealant evenly to the male threads and allow adequate cure time before pressurizing the system. Because this product has a flash point of 24.0 degrees C, keep it away from open flames and ignition sources during storage and application.
