Supex 574 Gasket Sealant

Supex 574 is a medium-strength anaerobic gasket sealing compound designed for machined, rigid metal flanges. Supex flange sealant is widely used in automotive, industrial, and mechanical applications for creating flexible, leak-proof seals.

Key Features of gasket sealing

• Anaerobic cure: Cures in the absence of air and in contact with metal.

• Forms a flexible seal between close-fitting metal surfaces.

• Fills gaps up to 0.25 mm (0.01 in).

• Excellent resistance to oil, coolants, and industrial fluids.

• Eliminates need for pre-cut gaskets, reducing inventory and waste.

  Uses of Supex 574 

  • Sealing rigid metal flanges and housings (e.g., gearboxes, pumps, engine covers)

  • Automotive and heavy machinery

  • Marine and power generation equipment

  • Replacement for paper, cork, and rubber gaskets
