Rubber Expansion Joints






Garlock Rubber Expansion Joints offer superior performance, reliability, and service life.



Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:

  • Absorb movement
  • Improved thermal stability
  • Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
  • Reduce mechanical noise
  • Compensate for misalignment
  • Eliminate electrolysis between dissimilar metals

At Garlock, the range of our engineering emphasis extends from the selection of the fabric used for reinforcement to the choice of materials used in actual expansion joint construction. Rigid laboratory and field tests of Garlock expansion joints are what back up our assurances of long life and reliable service. An important word on safety: all Garlock expansion joints carry safety ratings exceeding product specifications in such areas as pressure and movement. Garlock nonmetallic expansion joints and flexible couplings are ideally suited for hundreds of applications in a wide range of industries, including:

  • Power Generation
  • Pulp and Paper
  • Chemical Processing
  • Water/Waste Water
  • Marine
  • Mining
  • Heating, Ventilating, and Air Conditioning

Garlock Expansion Joints offer superior performance, reliability, and service life. This in turn improves plant safety, increases the mechanical integrity of equipment, and allows customers to gain a competitive advantage in the marketplace.
