Spool-type Rubber Expansion Joints

The Style 204 family of spool-type expansion joints are manufactured with the industry standard narrow arch design. This style is intended to be used in dynamic conditions where both pressure and vacuum concerns are present. 

Also available for high-pressure applications, Style 204 MAX has the highest pressure rating available inthe industry today. 

Garlock style 204 MAX is the highest pressure rated rubber expansion joint available in the industry today. Manufactured in North America, the 204 MAX is not only a solution for applications with extreme pressure requirements, but it is also tailored for high pressure Marine and offshore applications. The design of 204 MAX has earned the ABS type approval, making it the ideal solution for single point mooring stations requiring a 4:1 safety factor. The 204 MAX has also been extremely successful in many other applications, and has been specified in high pressure applications that pump water to copper mines.

The 204 MAX can be configured to meet specific customer needs and is compatible with virtually any media. The ABS type approval provides cost savings to end users by eliminating destructive testing during the requisition process.

Expansion joints for general service applications

Style 206 EZ-FLO® expansion joints contain a single wide flowing arch, eliminating the need for filled arches on slurry services. Suitable for high pressure applications, their self-flushing design eliminates media buildup and reduces fluid turbulence.

Style 206 EZ-FLO® can be designed to meet the requirements of ASTM F1123 and Navy/Coast Guard Specification 46CFR56.60-25(E).

  • Self-flushing design eliminates media buildup and reduces fluid turbulence
  • High pressure resistance ensures longer life and reduces inventory requirements
  • Lightweight design installs easily and costs less to ship
