AGIS, LLC now offers a compressible form-in-place expanded PTFE joint sealant tape, which conforms to almost any sealing surface.  

The joint sealing tape, manufactured of 100% pure expanded PTFE, is a soft compressible form-in-place gasket material that conforms to any surface, including rough, pitted, scratched and damaged surfaces. Among the possible applications are any accessible bolted joint that feature a flat or serrated sealing surface, such as round, oval, rectangular, complex and irregular flanges; raised face and flat face flanges; metal, plastic and glass-filled flanges. Ideal as joint sealant/sealing gasket for pump and compressor housing flanges; boiler and pressure vessel manholes and handholes,  heat exchangers, miscellaneous lids, access plates and ducts, among other sealing applications.  

Upon compression the expanded PTFE joint sealant tape forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal.  The expanded PTFE gasket tape is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.

AGIS's form in place gasket sealant tape performs under variable service conditions temperatures from -450° to 600°F and pressures from F.V. to 3000 psi. 

Other features of the expanded PTFE joint sealing gasketing tape include:  · FDA compliant  · Easy installation & removal  · Chemical resistant   · Same chemical inertness of pure virgin PTFE; no fillers or binders · Adhesive strip and peel-off backing for easy installation on both horizontal and vertical surfaces · Unlimited shelf life: no age deterioration · Resists creep and cold flow

AGIS's PTFE expanded joint sealant tape is available on spools in sizes ranging from 1/8" to 1" width and 15' to 150' lengths. Ask your AGIS customer service representative about custom sizes and shapes..
