Rectorseal PTFE Pipe Thread Sealant - 23551

Rectorseal PTFE Pipe Thread Sealant - 23551

Restore a leak-resistant threaded pipe connection with this universal/spec-match Rectorseal PTFE Pipe Thread Sealant - 23551. This PTFE-enriched thread sealant helps seal and lubricate threaded joints during assembly and service.

23551 is a universal/spec-match Rectorseal thread sealant used when threaded pipe joints need a dependable paste sealant rather than tape alone. Reapply it any time a threaded connection is disassembled or when an old joint compound has dried out and no longer seals reliably.

Compatibility: Metal and compatible plastic threaded pipe connections for plumbing, HVAC, and mechanical service where a PTFE-based paste thread sealant is specified.

Please confirm the fitting type, thread compatibility, sealant type, and intended service application before ordering.

Is it time to replace?

• Common Symptoms: Seepage at a threaded joint, bubbles during pressure testing, repeated small leaks after assembly, or connections that gall during tightening.
• Visible/Sensory Cues: Dried compound on the threads, old yellowed sealant residue, dampness around the fitting, or a connection that seeps after being reworked.

Pro Tip: Clean old compound from both male and female threads before reapplying sealant so the new layer can fill thread gaps instead of sitting on residue.
