DIN Flanged Single Sphere Rubber Expansion Joint
1. DIN Flanged Single Sphere Rubber Expansion Joint PN10 & PN16
The "DIN Flanged" refers to two end flanges of the rubber expansion joints that are in compliance with DIN flange standards. Usually there are two pressure-ratings of DIN flanges used in rubber expansion joints: PN10(10bar) and PN16(16bar). "Single Sphere" refers to the shape of the rubber bellow which is also called "body" of a rubber expansion joint. "Double Sphere Style" rubber expansion joints are available upon request.
