Retain ring system

ISO 6164 — 350/400 bar

For four-bolt square flange connections to ISO 6164 rated 350 and 400 bar, roughly 5000 to 5800 PSI, the retainer ring principle works just as well as it does for SAE ports. The series consists of welding flanges (VKR), welding systems (VKRK), reduction systems (VKR-RED) and bulkhead systems (VKR-B), together with the matching retainer rings and bonded seals. It is built for heavy hydraulics on presses, in mining, offshore and shipbuilding, where the SAE Code 62 sizes run out. Carbon steel or 316L stainless.
