Carbon steel hydraulic quick release coupling for ISO 7241-1 B Interchange Feature: 1. Poppet valves available to prevent uncoupled leakage. 2. Poppet valves open automatically when coupled, within rated working pressure, to keep the expedite flowing. 3. Critical parts are hardened for durability. 4. Durable ball-locking mechanism holds the mating halves together. 5. Socket and plug are precision machined from solid bar stock. 6. Carbon steel hydraulic quick release coupling series conforms to the standard of ISO7241-1B. Compatible with PARKER 60 Series: FASTER HNV Series: AEROQUIP FD45 Series and HANSEN HK Series. Application: Carbon steel hydraulic quick release coupling KZB sereis is mainly applied for hydraulic fluid lines as well as the chemical water, steam, and some gases transfer lines.
