Loctite branded flange sealing products help prevent leakage of liquids or gases. They create an impermeable barrier resistant to pressure, temperature and aging. Liquid anaerobic products or silicone seals precisely fill the space between the sealed elements for maximum contact. This also prevents corrosion of the components. The liquid gasket does not shrink, crack or deform, unlike traditional flat gaskets. The liquid Loctite gasket resists being pushed out from between flange fittings, unlike flat gaskets.

Advantages of Loctite liquid seals

• one-component products - easy and clean application
• universal, one product for many flange sizes, reduce inventory costs
• fill the entire space between the sealed elements
• it is not necessary to retighten the joints over time
  instant low pressure seal
• high resistance to solvents
• very good pressure resistance after full hardening (approx. 24 h)

Which product to choose for sealing flange connections?

When choosing a product, you should pay attention to the following factors:

• working temperature
• size of the gap between the flanges
• type of sealed material (metal - anaerobic products and silicones or plastic - only silicones)
• whether the seal should be stiff (anaerobic products) or flexible (silicones)

Surface preparation

Old sealant residues should be removed with Loctite 7200. Then degrease the surface with Loctite 7063. If the product is applied at temperatures below 5 ° C, use Loctite 7649.
