Fabric Expansion Joint
Accessories
1)Teflon Coated Fiberglass Sewing Thread
a. This is a machine sewing thread with a left-hand twist made from 100% fiberglass yarns coated with Teflon.
b. Available in other diameters other than the standard 0.021.
c. High tensile strength of 25.
2) KEY SEAL (Joint Sealant & Gasket Tape)
KEY SEAL is a 100% Virgin PTFE production. KEY SEAL Joint Sealant and Gasket Tape is a widely tested and proven way to seal liquids and gases of any kind in wet or dry service.
This highly fibrillated expanded PTFE exhibits flexibility, compressibility, stability under high temperatures, and high-tensile strength. The chemically inert product resists creep relaxation and maintains a seal even at extreme temperatures.
KEY SEAL Joint Sealant is ideal for worn flanges of all sizes. KEY SEAL Gasket Tape is a flat sealant designed for surfaces requiring a strip or full-face gasket.
Ease Of Use
Use scissors to cut to the desired length. The adhesive holds the sealant in place while positioning around the flange inside the bolt circle to isolate the flow media. The nonstick properties of PTFE allow the flanges to separate freely. The recommended size is about 40%-50% of the sealing surface. Remove the backing of the adhesive and loop it around the inside of the bolt circle, then overlap the ends of the joint sealant about 3/4 — 1 on either side of a bolt hole.
