The Best Pipe Thread Sealant of 2023

May 17, 2023

Pipe dope is a versatile compound but usually comes in cans of at least 4 ounces. That's just too much for most tool boxes. Rectorseal 25790 comes in a convenient tube to always be close at hand.

This soft-setting compound works on both plastic and metal pipe threads and is suitable for sealing pipes containing a wide variety of gases and fluids, including drinking water. When used with gas, air, or water at up to 100 psi, which covers most household installations, it can be pressurized immediately after the repair. The product's temperature range is from minus 50 degrees to 400 degrees Fahrenheit, and maximum pressures are 12,000 psi for liquids and 2,600 psi for gases.
