7551FG01_Silicon-filled modified PTFE flat gasket offers increased mechanical strength and improved cold flow resistance. It provides universal sealing performance across the entire pH range, and is particularly suitable for strong acids (except hydrofluoric acid) as well as other solvents such as fuels, steam, and chlorine. The **7551FG01 Gasket Insulation Sets** are widely used in petrochemical, pharmaceutical and food, shipbuilding, power stations, air separation, cryogenic media, and high-risk media sealing applications.

FAQ
1.Do GRE gaskets leak?

FRP gaskets do exhibit gas"permeation,"but this is not exactly a sealing failure at the flange face. High-end solutions add a PTFE sealing ring on the inner diameter of the gasket, which blocks the medium before it reaches the GRE body. For systems using **7551FG01 Gasket Insulation Sets**, it is recommended to prioritize installation procedure verification.

2.Why do insulation kits still fail to meet standards after installation?

Over 80% of insulation problems stem from improper installation. The most common issues are bolt-to-flange hole misalignment causing sleeve damage, failure to use a torque wrench resulting in uneven torque, and incorrect washer installation order (steel washers should directly contact the nut, not the insulating washer). Proper use of **7551FG01 Gasket Insulation Sets** can significantly reduce such risks.

3.How to verify successful insulation?

After tightening, a megohmmeter must be used to perform a resistance test across both sides of the flange, which is Generally, a level above megaohms is required to be considered acceptable. It is recommended to perform this test after each installation of **7551FG01 Gasket Insulation Sets**.
