UHP Screw-to-Connect Couplings

Robust screw-to-connect couplings with high flow rate and the ability to withstand harsh conditions. The Flat-Face design minimizes spillage during connection and disconnection. Compliance with ISO 14540 ensures complete interchangeability with other brands following the same standard. The standard version is equipped with a ball-type valve, but it is also available with a poppet valve for considerably higher flow performance.
