RUBBER-KU RUBBER PRODUCTS is a leading manufacturer and supplier of premium quality Full Face PTFE Gaskets designed for industrial piping systems that require exceptional chemical resistance, high temperature stability, superior corrosion protection, and long-term sealing reliability.
Manufactured using high-grade PTFE (Polytetrafluoroethylene), commonly known as Teflon™, our full-face PTFE flange gaskets are engineered to provide superior sealing performance in the most demanding industrial environments including chemical processing plants, oil & gas facilities, pharmaceutical factories, food processing industries, water treatment plants, semiconductor manufacturing, marine engineering, and heavy industrial operations.
The full-face gasket design completely covers the flange surface including bolt holes, ensuring uniform compression distribution, improved sealing efficiency, flange protection, and maximum leak prevention.
RUBBER-KU PTFE Full Face Gaskets are trusted by industrial engineers, maintenance contractors, piping specialists, OEM manufacturers, and industrial plant operators throughout Malaysia and Southeast Asia.
What is a Full Face PTFE Gasket?
A Full Face PTFE Gasket is a precision-engineered industrial flange gasket manufactured from PTFE material and designed to cover the entire face of a flange including all bolt holes.
Unlike conventional ring gaskets that seal only around the pipe bore area, full-face gaskets provide:
- Complete flange surface coverage
- Better compression load distribution
- Improved sealing efficiency
- Enhanced gasket alignment
- Reduced flange stress concentration
- Superior leak prevention
These gaskets are primarily used with flat-face flanges where even sealing pressure across the flange surface is critical.
The bolt holes help hold the gasket securely in position during installation, preventing movement, displacement, and gasket intrusion into the pipe flow path.
Why PTFE (Teflon™) is the Preferred Industrial Gasket Material
PTFE is one of the most advanced fluoropolymer sealing materials available in industrial engineering applications.
Its unique fluorocarbon molecular structure provides:
- Exceptional chemical resistance
- Outstanding temperature stability
- Ultra-low friction
- Excellent non-stick properties
- Superior weather resistance
- Long-term dimensional stability
These properties make PTFE an ideal sealing material for highly corrosive, chemically aggressive, and high-temperature industrial environments.
