This Gylon 3500 Insulating Gasket Set, produced by a factory in Zhejiang, provides you with reliable insulation. The core layer is made of Gylon 3500 specially filled polytetrafluoroethylene (PTFE), which offers excellent creep resistance and broad-temperature-range chemical resistance. Paired with G11 epoxy resin sleeves and G11+ZPS galvanized steel washers, it forms a complete insulation isolation system that effectively blocks current conduction and extends equipment service life. This Gylon 3500 Insulating Gasket Set is specifically designed for demanding flange insulation applications, with a 4-inch size, 150-pound rating, 1/8-inch thickness, and Type F design, fully compliant with ASME B16.5 flange standards. The minimum order quantity is 1 piece (MOQ=1), with a price range of 65–85 USD, flexible delivery lead times (7–35 days), and support for non-standard customizations. Whether in petrochemical, natural gas transmission, power generation, or offshore platforms, this Gylon 3500 Insulating Gasket Set helps you find the optimal balance between safe insulation and long-term stability.

Gylon 3500 is a high-performance silica-filled modified polytetrafluoroethylene (PTFE) gasket material. Through a unique manufacturing process, it effectively overcomes the inherent drawback of traditional pure PTFE gaskets—namely,"cold flow"(creep relaxation)—and significantly improves bolt torque retention, thereby delivering longer-lasting sealing performance. This material operates across an extremely wide temperature range, withstanding long-term exposure from -268°C to +260°C under extreme conditions, and a maximum pressure resistance of up to 83 bar. As the core sealing layer of this Gylon 3500 Insulating Gasket Set, this material provides the foundational performance for the entire insulation system.

Core Advantages
- Excellent chemical resistance: It withstands most strong acids, solvents, hydrocarbons, chlorine, steam, and other harsh corrosive media except for hydrofluoric acid, making it applicable across a broad range of industries. This is also the key reason why this Gylon 3500 Insulating Gasket Set is suitable for highly corrosive working conditions.
- Extremely low leakage rate: Compared with traditional PTFE, its sealing performance is superior, effectively reducing product loss and fugitive volatile organic compound (VOC) emissions, further enhancing the long-term reliability of the complete Gylon 3500 Insulating Gasket Set.
- Compliance and safety: The material complies with FDA and USDA regulations, making it suitable for applications with hygiene requirements such as food and pharmaceutical industries, and it does not support bacterial growth, ensuring that the Gylon 3500 Insulating Gasket Set remains safe and applicable in sensitive environments.

Application Scenarios
Based on the above characteristics, Gylon 3500 is an ideal choice for the chemical and hydrocarbon processing industries, and is particularly suitable for the following conditions:
- Corrosive fluid handling: Such as acid, alkali, and solvent transfer pipelines in chemical plants, where the Gylon 3500 Insulating Gasket Set is recommended to provide dual protection of insulation and sealing.
- Hydrocarbon and steam systems: Flange sealing in refinery and natural gas processing plants, where the broad-temperature-range tolerance of the Gylon 3500 Insulating Gasket Set can be fully utilized.
- Low-temperature and chlorine gas applications: With a minimum service temperature as low as -268°C, it is also suitable for sealing in the chlor-alkali industry, where the complete insulation structure of the Gylon 3500 Insulating Gasket Set is particularly critical.

Note: For oxygen service applications, the dedicated 3502 type product must be specified, and the standard configuration of this Gylon 3500 Insulating Gasket Set does not apply.
