Pipe compatibility
Pipe-material compatibility must be confirmed for the selected configuration. Supply the actual pipe material and measured outside diameter.
Consider MAXI where broader OD coverage is useful, or ULTRA where restraint is required from the connection.
Structure details
Ductile iron GGG-50 body and end ring, with epoxy coating, as listed in the product catalogue.
The catalogue lists EPDM, NBR or SBR seals and carbon-steel, SS304 or SS316 fasteners. Specify the required configuration for your application.
Specifications
Select the pipe OD range and check the mating flange dimensions in the complete catalogue size table. For example, Universal Flange Adaptor DN100 with a pipe OD range of 107–128 mm is a separate listed option from DN100 93–117 mm. Select by measured pipe OD and check the mating flange. Select the DN link in a row to include that exact range in your enquiry.
