ISO-A Quick Release Couplings

Male & female couplings allows for simple and safe connection and disconnection of hydraulic lines by pulling back the sleeve of the female coupling


The latching ball system allows positive and quick connection between couplings, and shut-off is by poppet valve to mitigate against leakage. Highly resistance materials, and a hardened male and sleeve to help with the brinelling effect. Suggested usage in hydraulic connections with no pressure in the line: agricultural and forestry equipment such as tractors, trailers, harvester machines; construction equipment and utility vehicles such as excavators, skid steer loaders, hydraulic tools; mining drills and industry. In cases where pressure exists in one or more of the hydraulic lines, please use appropriate under pressure connectors.
