Tubular flow sight glasses type 620K with plastic flanges

Brief description: Tubular sight glass made of PP / PVC or PVDF

The ACI Plastic tubular sight glass Type 620K is used wherever steel or stainless steel is not suitable for contact with your process medium. Solid plastic flanges of polypropylene (PP)polyvinyl chloride (PVC), or polyvinylidene fluoride (PVDF) include a borosilicate glass tube sealed with NBR or Viton O-rings. This design completely eliminates any contact between your process medium and steel parts.

Type 620K tubular sight glass is supplied fully assembled at the factory and is maintenance-free in operation. Should any components of the fitting nevertheless be damaged or worn, our team of technicians and sales staff will be at your disposal immediately to provide replacement at short notice. This will reduce downtimes of your plant to a minimum.

The sightglass fitting type 620K is equipped with connection flanges suitable for DIN EN 1092-1 PN16, but can be adapted to any flange standards or special connections on request.
