Since the 1950s, pipes have been sealed reliably with rubber o-ring gaskets. While simple in design, the o-ring joint and gasket are precise parts that must work together to seal properly. Press-Seal Gasket takes exceptional care in the specification and manufacture of o-ring gaskets. From our engineering review of the joint to our premium rubber compounds to our laser-controlled extrusion process, we ensure that our o-ring gaskets perform to the highest standard. Press-Seal o-ring gaskets conform fully with the requirements of ASTM C 361, ASTM C 443, ASTM C 1619, and AWWA Specifications as required
