TASK-LINE® Stainless Steel/PTFE Encapsulated Gaskets
Through a proprietary process, FDA approved, pure virgin PTFE resin is compression molded around and through a 304 stainless steel, perforated metal insert. After oven sintering, every PureFlex® TASK-LINE® PTFE lined gasket undergoes a 15,000-volt spark test to check for pinholes. The porous-free PTFE resin 100% encapsulates the stainless insert, isolating it from any fluid contact while in service.
Product Features & Benefits
- HANDLES AN EXTREME TEMPERATURE RANGE: TASK-LINE® gaskets have a temperature range of cryogenic to 400°F (consult factory for higher temperatures)
- NO MORE FABRICATION, EASY INSTALLATION: TASK-LINE® gaskets are molded to size, ½" through 24” in class 150# and 300# ANSI ratings with a thickness of ⅛" or 3/32” (other thicknesses available upon request). Installation is quick and simple. TASK-LINE gaskets are self-aligning and seat easily to any flange in almost any condition.
- CHEMICAL RESISTANT: to all acids, chlorides, sulfates, bleach solutions, solvents, phenols, caustics, and peroxides.
- LEAK FREE AND BUBBLE TIGHT: TASK-LINE gaskets offer maximum protection, are non-porous, leak-free, bubble-tight and can be used over and over without sacrificing sealing ability.
- ZERO CORROSION: TASK-LINE® gaskets have zero corrosion rates which contribute to lower life-cycle costs when compared to envelope or solid gasket types.
- BLOWOUT PROTECTION: the strength of the metal inserts provides critical blowout-proof protection.
- PTFE NON-STICK PROPERTY: allows the gasket to easily release from flanges during disassembly without any scraping.
