Anaerobic Flange Sealants
Industries Where Flange Sealant Can be Use
Ensures secure fastening in machinery operating under continuous stress.
WHY
Flange Sealants?
Flange sealants create a reliable, form-in-place gasket by filling surface irregularities between rigid metal flanges, ensuring leak-free sealing under pressure. They replace conventional gaskets, simplify assembly, and deliver long-term resistance to vibration, heat, and industrial fluids.
Advantages of Fasto Flange Sealants
- Easy single-component application
- Eliminates traditional gaskets
- Fills voids for leak-proof sealing
- High pressure and chemical resistance
FAQs
What are Flange Sealants Used For?
Flange sealants are commonly used for sealing rigid flange connections in:Gearboxes,
Pumps,
Compressors,
Engines,
Hydraulic systems,
Industrial machinery,
Transmission housings,
Valve assemblies.They help eliminate leakage while improving assembly reliability.
How Does a Flange Sealant Work?
Flange sealants cure when confined between metal surfaces and deprived of oxygen. Once cured, they form a durable seal that fills gaps, prevents leakage, and resists vibration, pressure, and thermal cycling.
What is The Difference Between a Flange Sealant and a Gasket?
Traditional gaskets are pre-formed materials placed between mating surfaces, whereas flange sealants are liquid compounds that cure in place. Flange sealants conform to surface irregularities, reduce inventory requirements, and provide uniform sealing across the entire flange surface.
Can Flange Sealants Replace Conventional Gaskets?
In many applications, flange sealants can replace conventional cut gaskets and gasket sheets. They are often used in rigid metal-to-metal flange assemblies where a reliable, leak-proof seal is required.
What Materials Can Flange Sealants be Used On?
Flange sealants are commonly used on:Steel,
Stainless Steel,
Cast Iron,
Aluminum,
Brass,
