Stucchi’s multi-year experience in screw-to-connect Flat Face couplings has led to the creation of VT, the new top-of-the-line series for this kind of couplings. Thanks to the new design with the axial bearing integrated in the male coupling and the automatic locking sleeve, the VT series is the right solution for heavy duty applications: even in presence of the most severe pressure impulses, vibration and rotation of the hoses, the correct functionality of the couplings is guaranteed.
