Its success is mostly because of the form, which enables perfect and easy closure. De symmetrical half couplings are tightened by turning the locking ring a quarter when it grips behind the lugs. The ensure even more tightness a Guillemin wrench can be used to turn the locking ring even further.On fixed installations often is chosen for a half coupling whithout a locking ring, seen only one locking ring is needed to tighten 2 couplings together.In some cases it is hard to couple a hose. In such a situation there can be chosen for a Guillemin coupling with a locking ring, but without the lugs.Specifications:Standard: EN 14420-8/NF E29-572Casting Method: Gravity Casting or Precision CastingSize: From DN40 (1-1/2") to DN100(4")Material: Alumiunium A356-T6 (Heat Treated), Staintless Steel 316, Brass and PPSeal: NBR, EPDM, FPM, PTFEThread: BSPSurface Treatment: Polishing or Sand-BlastWorking Pressure: 16bar/230psiTest Pressure: 30bar/435psiMinimum Blast Pressure: 50bar/725psiSizePart Number1-1/2"DN40SS 685402"DN50SS 685502-1/2"DN65SS 685653"DN80SS 685804"DN100SS 685100Technic:Detailed Images:
