Supex 574 Flange Sealant

Supex 574 Anaerobic Flange Sealant is a medium-strength gasket maker designed for sealing rigid metal flanges. It cures in the absence of air to form a flexible, leak-proof seal that resists oils, coolants, fuels, and industrial fluids. With a gap-fill capacity of up to 0.25 mm, it replaces conventional gaskets, prevents vibration-related leaks, and delivers reliable long-term sealing for automotive, industrial, and mechanical assemblies.

Product description

Supex 574 Anaerobic Gasket Maker – High-Performance Flange Sealant

Supex 574 is a top-quality anaerobic gasket maker. It acts as a reliable anaerobic flange sealant. This product seals rigid metal flanges perfectly. It cures without air. In addition, it works best when trapped between close-fitting metal surfaces. As a result, it forms a strong, flexible, and leak-proof gasket.

This anaerobic gasket maker shines where solid gaskets often fail. For example, vibration, heat changes, or surface flaws cause issues. However, Supex 574 handles them well. It provides strong sealing in engines, gearboxes, pumps, compressors, and machinery.

Key Features & Benefits

  • Delivers 100% leak-proof performance.
  • Suits rigid metal-to-metal flanges.
  • Creates a durable seal.
  • Resists oil, fuel, water, and chemicals strongly.
  • Stops loosening from vibration or pressure.
  • Replaces traditional cut gaskets easily.
  • Fills small surface flaws.
  • Applies smoothly with good control.
  • Allows simple disassembly without damage.

Applications of Supex 574 Anaerobic Flange Sealant

  • Rigid metal flanges & housings — Forms leak-proof, in-place gaskets on machined, close-fitting metal surfaces.
  • Engine and transmission housings — Seals automotive engine blocks, valve covers, oil pans, and transmission casings reliably.
  • Gearboxes and covers — Ideal for industrial gearboxes, differentials, and camshaft/transmission covers in heavy machinery.
  • Pumps and compressors — Ensures durable sealing in water pumps, fuel pumps, hydraulic pumps, and air compressors.
  • Hydraulic & pneumatic systems — Provides vibration-resistant, oil/chemical-proof joints in high-pressure assemblies.
  • Automotive & heavy machinery — Used in cars, trucks, tractors, generators, and railway engines for critical flange joints.
  • Industrial sectors — Power plants, steel mills, mining, textiles, marine equipment, and process industries for machinery flanges.

Supex 574 excels in demanding environments requiring instant low-pressure seal and long-term resistance to fluids/vibration.

Why Supex 574 Anaerobic Flange Sealant Beats Traditional Gaskets

  • No compression loss or creep — Unlike conventional gaskets that flatten and lose seal over time, Supex 574 maintains consistent sealing.
  • Eliminates gasket stock & cutting — Ends inventory, pre-cut gaskets, and manual cutting; forms in-place for any flange.
  • Even, full-flange sealing — Seals entire surface uniformly, filling gaps up to 0.25mm and imperfections better than rigid cut gaskets.
  • Superior vibration & pressure resistance — Prevents loosening and leaks from vibration/shock; traditional gaskets often fail here.
  • Stronger chemical & fluid resistance — Resists oil, fuel, coolants, chemicals long-term; outperforms paper, cork, or rubber gaskets.
  • Reduces corrosion & downtime — Stops flange corrosion; durable, reliable seal boosts maintenance intervals and assembly life.
  • Easy disassembly — Allows clean removal without damage, unlike stuck or torn pre-cut gaskets.

Supex 574 delivers leak-proof, long-lasting performance for metal flanges in engines, gearboxes, pumps, and industrial use.

FAQs

What is Supex 574?

It’s a medium-strength anaerobic gasket maker that cures in the absence of air between rigid metal flanges, forming a durable, leak-proof seal.

How long does it take to cure?

Provides instant low-pressure resistance; fixtures in about 1 hour, full cure in 24 hours for maximum strength and high-pressure hold.

What gap size can it fill?

Fills gaps up to 0.25 mm on close-fitting, machined rigid metal surfaces.

Which materials is it suitable for?

Best for rigid metal-to-metal flanges (steel, cast iron, aluminum); not for plastics or large gaps/flexible joints.

How to apply it?

Clean flanges thoroughly (remove oil, grease, old material), apply a thin continuous bead to one surface, assemble immediately, and tighten to spec.

What does it resist?

Resists oils, fuels, chemicals, water, coolants, vibration, and thermal cycling in demanding conditions.

Can it be disassembled?

Yes, medium strength allows easy disassembly without surface damage.

Is it suitable for engines/gearboxes?

Yes — ideal for engine casings, gearboxes, pumps, compressors, and hydraulic/pneumatic systems.
