Connection and selection

Closure point

Specify the opening DN and the required flange drilling. The catalogue mass columns do not by themselves establish current working pressure.

Flange interface

Match the flange DN and drilling to the mating component. Select the gasket and fasteners for the specified assembly.

Size and installation

Check the product-specific drawing for the required lengths and clearances. Confirm current pressure applicability and available sizes for the project.

Product FAQs

What information should I send for a Blank Flanges enquiry?

Send the required DN, working pressure or pressure class, flange drilling or mating flange details, material or coating requirement, quantity, destination and any project drawing or document requirement.

What do the PN10, PN16 and PN25 columns in the catalogue image represent?

In the catalogue they appear under the Mass heading. They do not by themselves confirm current working pressure or offerability; Aquafitting must confirm both before quotation.

Are the current material, coating and flange drilling confirmed on this page?

No. These details remain missing and must be confirmed by Aquafitting against the project before quotation.

Product FAQs

What information should I send for a Blank Flanges enquiry?

Send the required DN, working pressure or pressure class, flange drilling or mating flange details, material or coating requirement, quantity, destination and any project drawing or document requirement.

What do the PN10, PN16 and PN25 columns in the catalogue image represent?

In the catalogue they appear under the Mass heading. They do not by themselves confirm current working pressure or offerability; Aquafitting must confirm both before quotation.

Are the current material, coating and flange drilling confirmed on this page?

No. These details remain missing and must be confirmed by Aquafitting against the project before quotation.
