Plastic Tubular Sight Glass Type 620K – PN 10 – DIN EN 1092-1

The plastic tubular sight glass type 620K is used when steel or stainless steel are not suitable for contact with the process medium.

• Solid flanges in polypropylene (PP), PVC, or PVDF surround a borosilicate glass tube.
• The glass is sealed with NBR or Viton® O-rings, eliminating any contact between the process medium and metallic parts.

The 620K tubular sight glass is delivered fully factory-assembled and requires no maintenance during operation.

The flanged connections of the 620K type are compatible with DIN EN 1092-1 and can be adapted to other flange standards or special connections upon request.
