RECTORSEAL 17432 Pipe Thread Sealant

This non-hardening pipe thread sealant comes in a 16 oz brush-top can for straightforward application. It suits plumbing and maintenance professionals who need reliable sealing on metal piping systems. The black compound handles air, alcohol and fuel lines across a broad temperature range. It is built for daily use on aluminium, brass, copper, galvanised steel, iron and stainless steel.

Replaces hardened tapes

The non-hardening formula stays pliable so joints absorb movement without leaking. Switch when you need a seal that survives thermal cycling from -50 Degrees F to 450 Degrees F. The jump is worth it on systems that see repeated pressure swings or vibration. It removes the rework caused by brittle sealants that fail after a few heat cycles.

Brush-top can lets you coat threads directly

Clean male threads thoroughly before brushing on an even layer to avoid voids. Over-application can push excess compound into the flow path so use a light coat. The product is restricted in California under Proposition 65 for reproductive-harm chemicals. Not rated for maximum gas or liquid pressure so verify system limits before use.

Questions about this item

What thread size does the 16 oz brush-top can accommodate?

The sealant is applied directly to male pipe threads of any standard size; the brush top lets you coat the full thread circumference before assembly.

Which step do users most often skip when applying this non-hardening sealant?

Stirring the black compound until the colour is uniform ensures the PTFE and fillers stay suspended, preventing thin spots that can leak.

How often should the sealant be reapplied on a joint that sees 450 °F service?

Because the formula never hardens, the joint can be broken and re-sealed with fresh compound whenever the connection is disturbed; no scheduled replacement is needed.
