Sealex (Joint Sealant)

Sealex joint sealant is a specially processed gasket material that is 100% pure PTFE on a roll. It 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.

Soft-Chem (Expanded PTFE Sheet)

KLINGER Thermoseal soft-chem expanded PTFE sealing material provides excellent corrosion resistance and impermeability along with superior creep resistance. The material's high compressibility enables it to deform under load and conform to irregularities in flange faces for a tight seal with low, minimum sealing stress. This product can be used in a broad range of applications.
