Gummed round GR


The GR flange is basically the same as the FR flange but comes without the rear steel flange. This design is often used in areas where hoses are built into machines or when seal effects are required on both sides of the flange. One particular area of application for this type of flange is in the construction of squeeze valves. When using this flange it must be noted that for manufacturing reasons, the flange thickness is characterised by its high level of tolerance.

The flange-type GG is a variety of the type GR, which has no built in steel reinforcement. It is flexible and available with small thickness. Type GG-flange is not suited for use in pressure pipings.
