Purpose-built pipe sealant

RectorSeal 31551 Tru-Blu is a non-hardening pipe thread sealant supplied in a 9.6 fl oz brush-top can. The blue compound stays pliable after application and resists vibration loosening on threaded joints. It is formulated for industrial and commercial plumbing installations where a reliable seal must be made quickly. The brush applicator allows controlled coverage on male threads without extra tools.

Plumbers and maintenance teams

This sealant suits installers who need a vibration-resistant joint on piping carrying water, steam, air, natural gas, diesel fuel oil, fuels or kerosene. It operates reliably between 20 and 140 degrees F and handles up to 2,000 psi gas pressure or 8,000 psi liquid pressure. Systems requiring a hardening compound, anaerobic cure chemistry or compatibility with fluids not listed above should use a different product.

Pressure and temperature envelope

The decisive specification is the combined pressure and temperature rating: 2,000 psi for gases and 8,000 psi for liquids from 20 to 140 degrees F. If the design pressure or operating temperature of the piping system falls outside these limits, this sealant cannot be specified for that joint.

Questions about this item

Which container size of Tru-Blu sealant should I choose for a typical plumbing job?

The 9.6 fl oz brush-top can covers many residential and light-commercial joints with one container.

What does the 2,000 psi gas rating mean when the sealant is on threaded pipe?

It holds natural gas, air and similar gases at up to 2,000 psi without leaking when applied to clean threads.

How does the non-hardening cure affect the seal on vibrating lines?

The paste stays flexible, so vibration from pumps or engines will not crack the seal on diesel, water or steam lines.
