Form-in-Place Sealex® Joint Sealant

Sealex®Sealex® 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 Sealex® 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, Sealex® has good creep resistance and bolt torque retention properties.

Sealex® 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.

It 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).

KLINGERSIL® C-7400 Isolation Gaskets

Application Overview:

Some applications in plants call out for isolation kits to maintain the integrity and reliability of a pipeline and piping system. Isolation kits are designed to work in conjunction with flanges, gaskets, and/or bolt sleeves and washers by eliminating metal-to-metal contact and halting static electric currents. At times they are relied upon for critical applications in severe temperatures and conditions.

KLINGERSIL C-7400 - Isolation Gaskets replace Isolation Kits

The Problem: 

Industry’s first choice are phenolic gaskets. They are often supplied in kits, but they are hard and typically take a lot of load to seal. And lack of load is the number one reason for gasket failure.
