LOCTITE 518 Gasket Sealant 50ml

LOCTITE 518 Gasket Sealant 50ml

Medium-Strength Anaerobic Flange Sealant for Metal Surfaces (50ml)

Reliable Sealing for Precision Metal Flanges

When you’re working with close-fitting metal components, LOCTITE 518 Gasket Sealant 50ml steps in as a dependable alternative to traditional gaskets. This semi-flexible, medium-strength anaerobic sealant forms a strong and adaptable seal between cast iron, aluminium, or steel flanges, offering outstanding performance even on imperfect or contaminated surfaces. Whether you’re in maintenance, assembly, or repair, LOCTITE 518 helps you streamline processes and achieve leak-proof reliability—every time.

Designed for Precision Metal Applications

Unlike traditional pre-cut gaskets, LOCTITE 518 Gasket Sealant 50ml fills surface gaps up to 0.25 mm, conforming to irregular flange faces with ease. Its gel-like consistency ensures mess-free application, prevents dripping or running, and keeps flanges properly aligned during assembly. This makes it especially useful for vertical surfaces or complex configurations.

As soon as it’s confined between metal parts and isolated from air, LOCTITE 518 Gasket Sealant 50ml begins curing rapidly. Within minutes, you get an initial low-pressure seal, and once fully cured, it resists high pressure and aggressive chemicals alike.

Key Performance Advantages

• Medium Strength: Strong enough to withstand vibration and pressure but still allows for disassembly without damage.

• Chemical Resistant: Seals won’t crack, tear, or degrade when exposed to oil, coolants, or other industrial fluids.

• Wide Compatibility: Works equally well on active metals like copper or brass and inactive ones like aluminium or stainless steel.

• NSF P1 Approved: Safe for incidental food contact, making it ideal for food processing equipment.

Slash Downtime and Inventory Costs

LOCTITE 518 eliminates the need to stock large quantities of different gaskets, reducing your costs and simplifying your toolkit. It speeds up assembly lines, improves sealing reliability, and cuts out human error involved in gasket cutting or fitting.

Ideal Applications

• Motors & Engines: Perfect for sealing motor housings and cylinder flanges.

• Gearboxes & Transmissions: Ensures leak-free assembly of rigid mechanical components.

• Industrial Equipment: Provides long-lasting seals in harsh environments with frequent exposure to fluids.

• Food Processing Machinery: Approved for use in NSF-regulated environments where sanitation and performance matter equally.
