iso b series

IRB I IRBO I IRBX SERIES

The IRB Series Quick Couplings are interchangeable to ISO B standard (ISO 7241-B). The IRB is offered in three different high quality materials to meet different application challenges—IRB carbon steel with Nitrile seals, IRBO brass with Viton seals, and IRBX 316 stainless steel with Viton seals. The entire series features compact design, AISI 302 stainless steel springs, and PTFE anti-extrusion rings.
