INERTEX® UHF Gasket Tape
Form-in-place "full face gasket on a roll"
INERTEX® UHF (Uniformly and Highly Fibrillated) Gasket Tape offers exceptional performance that shares the same advantage characteristics of reduced creep relaxation and cold flow with UHF Joint Sealant. The tape is soft and adaptable to any flange surface, ensuring a tight fit. It can be easily pierced to accommodate bolts for full face gasket applications. Moreover, it can be configured as both inboard and outboard strips around the bolt circle, reducing the overall gasket area. The tape features a pressure-sensitive adhesive on one side, enabling effortless installation on flanges and sealing faces, regardless of the application’s orientation.
Product Features:
- Wide pressure and temperature range
- Unsurpassed chemical compatibility
- Excellent creep and cold flow resistance
- Will not harden or deteriorate with age
- Low coefficient of friction allows easy removal
- Easily conforms to damaged or pitted flanges
- Low compressive load to seal
- Wide adhesive strip for easy installation for all shapes, vertical or horizontal
- “Full Face Gasket on a Roll”
INERTEX® UHF (Uniformly and Highly Fibrillated) Gasket Tape is a versatile product widely used for sealing tank and vessel lids, manways, and irregular-shaped openings. It provides leak-tight sealing in ducting systems, and paint spray booths, and serves as insulation tape. It can also repair worn spiral wounds or grooved metal gaskets. Its adaptability makes it a convenient “full face gasket on a roll” solution.
