This is a PTFE gasket suitable for low-tightening flanges.
This envelope gasket is designed to have a resilient core covered with a thin PTFE outer layer, allowing for sealing at relatively low surface pressure while maintaining the properties of PTFE.
We offer three types of outer shell shapes depending on the application! Introducing products with excellent non-adhesive and electrical properties.
The "S-5000T series" is a PTFE encapsulated gasket with a PTFE outer layer covering the core material, such as joint sheets. It has a rich lineup including the basic type "S-5000T," the large diameter "S-5010T," and the right angle (for preventing liquid accumulation) "S-5020T." This product is non-contaminating, resistant to chemicals, non-adhesive, and has excellent electrical properties. Please feel free to contact us when you need it. 【Features】 ■ PTFE outer layer encapsulating the core material such as joint sheets ■ Excellent non-contaminating and chemical resistance ■ Superior non-adhesive and electrical properties ■ Sizes: Thickness 1.6mm, 2.8mm, 3.8mm ■ Three types of outer layer shapes available according to application: - Basic type (V-shaped cross-section), large diameter (U-shaped cross-section), right angle (L-shaped cross-section) *For more details, please refer to the PDF document or feel free to contact us.
Compatible with small diameter sizes using a water jet.
■Overview of Processing Example Product Name: Teflon Coated Gasket / Dimensions: φ128×φ105×2.8t / This processing example features a Teflon coated gasket with TOMBO No.1120 as the core material, wrapped in PTFE. It was manufactured for a chemical plant. In addition to the heat and steam resistance of the expanded graphite sheet core, the outer PTFE layer provides excellent chemical resistance. Due to its small diameter, high-precision cutting was achieved through water jet processing. ■Product Features TOMBO No.1120 is a joint sheet primarily composed of expanded graphite, with added aramid fibers and NBR. It excels in heat resistance, steam resistance, and corrosion resistance, and is flexible and resistant to scratches. It is suitable for water, steam, oil, exhaust gases, etc., and is widely used in relatively high-temperature flanges and valves in petroleum refining, chemical plants, and power plants.
