Joint Sealant
PTFE-Based Thread & Flange Sealant
PTFE joint sealant is the thing that saves you at 2 am when the right gasket isn't in the store. It's a flexible cord that conforms to any flange face shape, thread form, or irregular surface, including pitted or scored faces that a flat gasket won't seal against. Multiple diameters, supplied on reels.
Types & Variants
Standard PTFE Cord
Expanded PTFE sealant cord for general-purpose flange and thread sealing. Suitable for water, gas, steam, and most chemicals.
Pre-Formed Strip
Flat PTFE strip for wide or shallow flange faces where round cord would not seat properly.
Common Applications
Emergency Gasket Replacement
When pre-cut gaskets are not available, joint sealant can be formed on site to seal flanges immediately.
Damaged Flange Faces
Conforms to pitted, corroded, or scored flange surfaces that a flat gasket cannot seal against.
Pipe Threads
Wraps onto pipe threads as a PTFE thread seal for pressurised connections in water, gas, and chemical lines.
Non-Standard Connections
Odd shapes, oval flanges, and equipment covers where standard gasket shapes are not manufactured.
