LOCTITE, Canada’s leader in sealants and adhesives, is introducing new innovative products to the industrial market.


Cut gaskets leak, they tear, they relax. They can’t fill all the voids and surface imperfections. Liquid gaskets from LOCTITE are more reliable. They fill all gaps with total surface coverage every time. And unlike cut gaskets, every shape & size needed is always on hand.

The new LOCTITE 518 applicator pen is the fastest and easiest way to apply liquid gaskets. It forms a flexible, high strength, chemical resistant seal that fills all voids and will not tear, break, distort or decay.

The 518 pen can be used on rigid iron, aluminum and steel flanged mating surfaces, including surfaces that have minor contamination. It combines the leak-fighting properties of 518 Flange Sealant with a roll-on applicator that makes applying a liquid flange sealant easier than ever with less waste and less mess. LOCTITE 518 also helps to reduce inventory because one package will do for any size or shape gasket.

Whatever your need, you can count on the flexibility and reliability of the LOCTITE 518 pen.


Introducing the new LOCTITE NS 5540 and NS 5550 which are thermally activated sealing compounds that are specifically designed for use in high temperature and high-pressure environments. These products cure in the presence of heat to form a mechanical seal on metal-to-metal flanges and fittings. They are also designed to allow for disassembly for future maintenance and repairs.

Suitable for high pressure steam applications, LOCTITE NS 5540 brushable liquid can seal flanges carrying up to 2900 psi (200 bar) steam at temperatures up to 1300°F/700°C.

LOCTITE NS 5550 is a fibrous paste sealant designed for high temperature (up to 1500°F/815°C) and high-pressure applications (up to 5000 psi/340 bar).

These sealants are chemical resistant and suitable for sealing steam, hydrocarbons, gases and other process fluids in high pressure, high temperature environments. They can be used on turbine split casings, pump casings, boilers, steam traps, ductwork, stacks, heat exchangers and exhaust systems, typically found in power generation facilities, pulp and paper mills, mines and, and oil and gas refineries.

LOCTITE NS 5540 and NS 5550 are reliable, easy to use, allow for simple disassembly, and are not affected by thermal cycling. Most importantly, these products are backed by Henkel’s sales and technical support.

For liquid gaskets that offer reliability, ease of use, and simple disassembly, Loctite is the brand name to trust. We’ll even prove it to you, with a free sample for qualifying participants: or contact us.
