Expanded PTFE joint sealant, specially processed, 100% pure PTFE on a roll, provides soft, highly compressible gasketing for longer life and trouble-free sealing. Its form-in-place versatility also cuts maintenance and storage costs. The high compressibility of Expanded PTFE joint sealant enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a very wide, thin ribbon-like joint sealant. Unlike conventional PTFE which is prone to cold flow, it has good creep resistance and bolt torque retention properties

Expanded PTFE joint sealant does not support bacterial growth or cause product contamination and is FDA compliant. It has virtually no shelf-life concerns since PTFE is unaffected by normal environmental conditions.

Expanded PTFE joint sealant has excellent resistance properties to chemical attack. It is ideal for most chemical services at temperatures to 500°F (260°C) and pressure to 2,000 psi (138 bar). It is also suitable for cryogenic use to -321°F (-196°C).

The sealant is available in roll form which helps reduce storage space, and is available in a wide variety of thicknesses and lengths.

Easy to Use:

Just follow the simple installation instructions.

Use a size with nominal width of between 1/3 and 1/2 of the effective flange sealing width.

  • Make sure that the sealing flanges are clean.

  • Cut off a length of Sealex just a little longer than the actual circumference of the perimeter of the seal.

  • Peel off the adhesive protection strip, and press the Sealex into position. Cross the free ends of the Sealex adjacent to the bolt hole.

  • Bolt up the mating surfaces using the recommended clamping force and bolt tightening patterns.
