7551FG01 Insulation Gasket Sets are specifically designed for 40-inch large-diameter flanges, conforming to the ASME B16.47B-WN-RF standard. The gasket set utilizes high-performance 7551 non-metallic insulating material, with a thickness of 1/8"and a pressure rating of 150#. It includes an F-type sealing gasket, a G11 insulating sleeve, and G11+ZPS combination washers, achieving complete electrical isolation and long-term sealing between flanges. Directly supplied by the original manufacturer in Fujian, with a minimum order quantity of 1 set, a delivery lead time of 7-35 days, customization is supported, and the unit price ranges from 1,250 to 1,450 USD. As a professional 7551FG01 Insulation Gasket Sets, its core advantage lies in system-level insulation integrity, rather than the performance of a single gasket.
IDT UNIFLUOR-7551 is a modified polytetrafluoroethylene (PTFE) composite material, specifically designed for demanding chemical environments and insulating applications. It is a key sealing component of the 7551FG01 Insulation Gasket Sets. It is primarily used in large-diameter flange connections where it is necessary to completely eliminate/isolate the electrochemical corrosion path.
Main Application Scenarios:
- Chemical and Petrochemical Industry: Especially suitable for media such as strong acids, strong alkalis, and organic solvents. The excellent creep resistance and cold flow resistance of the 7551 material enable it to withstand severe pressure and temperature fluctuations in pipelines, avoiding leaks caused by torque loss due to creep commonly seen in ordinary PTFE gaskets. In such scenarios, choosing the 7551FG01 Insulation Gasket Sets meets both sealing and insulating requirements simultaneously.

In such scenarios, choosing the 7551FG01 Insulation Gasket Sets meets both sealing and insulating requirements simultaneously.
- Chlor-alkali and Metallurgical Industry: Areas with high requirements for media purity and the presence of stray currents, such as electrolytic cell outlets and metal smelting pickling lines. Combined with insulating sleeves and washers, the 7551FG01 Insulation Gasket Sets simultaneously solve the dual challenges of"sealing against highly corrosive media"and"electrical insulation of flanges."
- Oil & Gas Platforms and Marine Engineering: Its inherent hydrophobicity and weather resistance make it suitable for complex mixed media like seawater, hydrocarbons, and hydrogen sulfide, effectively preventing galvanic corrosion caused by potential differences on flange faces. The application of 7551FG01 Insulation Gasket Sets in this field has proven its long-term reliability.
Comparison with Gylon 3500 Gasket:
The Gylon 3500 gasket is also a benchmark in the modified PTFE industry, but the design focuses differ:
1. Material Structure Difference: The Gylon 3500 gasket has a multi-layer, bi-directionally oriented structure using micro-porous membrane technology. It has higher hardness, extremely strong creep and blow-out resistance, and its design focuses on long-term safe operation in strong alkalis and medium-concentration acids. IDT UNIFLUOR-7551, on the other hand, uses special filler modification, emphasizing a homogeneous structure. It performs exceptionally well in terms of resistance to strong acids (including hydrofluoric acid) and permeation, and offers excellent compression and recovery properties, making low-pressure sealing easier to achieve.

2. Insulation Adaptability: In the 7551FG01 Insulation Gasket Sets, the UNIFLUOR-7551 gasket works synergistically with the G11 insulating components. Compared to a Gylon 3500 gasket paired with general-purpose washers, this specialized, kit-based design – namely the 7551FG01 Insulation Gasket Sets – provides higher insulation integrity on large-diameter ASME B16.47B flanges, offering a more reliable system-level electrical insulation solution rather than just gasket body performance.
