Gasket Makers & Flange Sealants

Gasket makers and flange sealants help form, supplement or maintain seals on compatible mating surfaces. They are used across workshop and industrial maintenance where the joint design, service fluid, temperature, pressure and equipment procedure permit a liquid sealant. They do not correct warped flanges, damaged housings, incorrect torque or a gasket that should be replaced.

Select for the joint and service environment

Confirm whether the application uses a formed-in-place gasket, a conventional gasket with a specified sealant, a flange sealant or another method. Then check fluid compatibility, temperature limits, pressure, gap-filling ability, surface material, cure requirements and the disassembly expectations. A product appropriate for one engine, gearbox or housing may be unsuitable for another.

Surface preparation determines seal performance

Remove old gasket material without damaging the mating face, clean the surface as directed, and make sure it is dry where required. Apply the stated bead or film thickness; excess sealant can be squeezed into a component and create its own problem. Assemble within the working time, follow the tightening sequence and permit the full cure before fluid, pressure or load is introduced.

Gasket Makers & Flange Sealants FAQs

Can gasket maker replace every conventional gasket?

No. Use a liquid sealant only where the equipment manufacturer and sealant product instructions permit it. Many assemblies require a specified gasket, surface treatment and torque method.

How much sealant should I apply?

Apply the bead or film stated by the manufacturer. More is not better: excessive product can contaminate internal passages or prevent correct joint seating.

When can the joint be put back into service?

Follow the product’s specified cure time for the actual fluid, temperature and joint condition. Handling time is not always the same as full service cure.
