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 joint sealant enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a wide, thin, ribbon-like seal. Unlike conventional PTFE which is prone to cold flow, joint sealant has good creep resistance and bolt torque retention properties.
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.
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.
