This 300LB Gylon3500 Insulation Gasket is specifically designed for 18-inch ASME B16.5 raised face flanges, serving as a critical sealing solution to prevent electrochemical corrosion. It features Gylon3500 high-performance modified PTFE sheet material with a thickness of 1/8 inch (3.2 mm), offering excellent chemical resistance and an exceptionally low creep relaxation rate. The Type F configuration comes complete with G11 insulating sleeves, washers, and ZPS isolation gaskets, achieving comprehensive electrical insulation among the flange, bolts, and pipeline. Whether in cathodic protection systems or dissimilar metal connections, this single kit eliminates galvanic corrosion and ensures long-term, reliable sealing. We support single-piece ordering and size customization, with delivery within 7 to 35 days.
300LB Gylon3500 Insulation Gasket — The Sealing Solution That Completely Stops Electrochemical Corrosion
In flanged connections, there is a hazard often overlooked yet capable of silently eating through pipelines: galvanic corrosion. Especially when dissimilar metals come into contact, or when pipelines operate under cathodic protection systems, electrical current seeks every available path — flange faces, bolts, all can become sacrificial victims. Ordinary sealing gaskets are powerless against this threat, which is precisely why our 300LB Gylon3500 Insulation Gasket was created.
In flanged connections, there is a hazard often overlooked yet capable of silently eating through pipelines: galvanic corrosion. Especially when dissimilar metals come into contact, or when pipelines operate under cathodic protection systems, electrical current seeks every available path — flange faces, bolts, all can become sacrificial victims. Ordinary sealing gaskets are powerless against this threat, which is precisely why our 300LB Gylon3500 Insulation Gasket was created.
This gasket kit suits ASME B16.5 standard, 18-inch raised face flanges, utilizing Gylon3500 sheet material with a thickness of 1/8 inch (3.2 mm). Gylon3500 is a specially modified PTFE material that not only inherits the near-universal chemical resistance of polytetrafluoroethylene — capable of handling virtually all media from strong acids and alkalis to a wide range of solvents — but, more critically, its creep relaxation rate is far lower than that of ordinary PTFE. This means that under demanding operating conditions with fluctuating temperatures and pressures, the gasket will not easily thin out or lose resilience; sealing stress remains durably stable, fundamentally reducing the risk of leakage caused by gasket relaxation.
"Insulation"is where its true soul lies. We provide a Type F complete insulation kit, including G11 epoxy glass fiber insulating sleeves, insulating washers, and ZPS isolation gaskets. This combination achieves full-range electrical isolation among the flange, stud bolts, and pipeline, thoroughly severing the path of corrosive current. Whether you are connecting carbon steel to stainless steel, or protecting underground pipelines from stray current interference, a single kit provides a one-stop solution from sealing to insulation — no more sourcing parts from different suppliers, and no worries about the entire protection being rendered useless due to a single overlooked insulation point.
In terms of delivery, we understand that every project follows its own rhythm. We support single-piece ordering, offering great convenience for small-batch maintenance or emergency replacements, freeing you from the burden of tying up inventory just to meet minimum order quantities. Meanwhile, dimensions and thicknesses can be flexibly customized according to actual operating conditions, with delivery times controlled between 7 and 35 days — balancing the efficiency of standard product supply with the flexible responsiveness required for non-standard demands.
A proper gasket protects not just a single pipeline, but the long-term integrity and operational safety of the entire system. If you are facing insulation challenges with dissimilar metal flanged connections, this 300LB Gylon3500 Insulation Gasket will be your reliable technical choice.
