Garlock MULTI-SWELL™ Gasket Style 3760

Garlock Multi Swell GasketsThis Multi Swell Gasket material is specially designed to swell when in contact with water or aliphatic hydrocarbons, such as petroleum oils, fuels and solvents. Garlock Multi Swell Gasket material is manufactured from a combination of aramid fibres and a Garlock proprietary rubber binder.

Multi Swell Gaskets explained

The swelling of the material used for Multi Swell Gaskets ensures a seal when the bolt load is insufficient to compress a traditional fibre gasket. However, this could potentially crush an elastomeric gasket. When the material makes contact with water or oils, the Multi Swell Gasket load is increased through swelling. This Garlock MULTI-SWELL™ Gasket material is twice as compressible as standard fibre gaskets and is able to create a seal with an irregular surface. Therefore, this makes the Multi Swell Gasket ideal for preventing leaks in applications such as:

  • Gearboxes
  • Pumps
  • Compressors
  • Lube oil systems
  • Access covers

Garlock MULTI-SWELL™ Gaskets are also available to purchase in the following styles:

Style 3760-U: This Multi Swell Gasket is NSF-61 certified.

Style 3760-Nuclear: This Garlock MULTI-SWELL™ Gasket is 10CFR 50 Appendix B Certified.
