1. Basic Information

 

expansion joint are ideal in heating and air conditioning systems, where low initial cost and maximum reliability are a must.

 

The flexible connectors have EPDM cover, providing excellent resistance to sunlight, ozone, oxidation and is resistant to damage from dropping oil.

 

The unit has EPDM tube, which is good for hot, and cold-water service & mild chemicals.

The fully molded Single Sphere design provides greater flexibility, thus protecting mating flanges, especially PVC  and fiberglass types.

 

The steel flanges easily rotate on the bellows,which makes it easier to line up the bolt holes during installation when mating flanges are out of line.

 

Separate retaining rings are never required. With a temperature rating of -20°C

 to 100° C ., the standard sizes range from 1" through 12" I.D. can be with the working pressure at 300 psi, Sizes 14" through 24" have working pressure at 150 psi.
