ADVANTAGES Flat mating faces are easily wiped clean to prevent the ingress of contaminants. Streamlined internal flow path minimises the pressure drop. Non-spill design avoids fluid loss during connection and disconnection. No air intrusion during connection. Locking sleeve prevents accidental disconnection. Bi-directional flow. Sizes 3/8" and 1/2" comply with HTMA interface requirements and are recommended by the BHTMA for use in equipment manufactured by its members. Conforms to current ISO 16028 Standard sizes. PREMIER FEATURES Robust construction. High working and burst pressure ratings. Excellent fatigue life. Female coupling seal swaged-in to prevent extrusion under pressure. Dynamic seal geometry in male couplings allows bi-directional flow.
