Flanges

Looking for a gas valve Flange? Or a Flange to replace the broken inlet on your gas train? Whether it be a screwed flange, a bolt-on flange, a weldable flange or a custom flange to suit a specific application you are repairing or designing, we can offer a replacement.

Which size flange do I need?

As standard flanges are measured across the ID of the inlet in inches. For screwed flanges, the size will be represented with a DNxx in some instances. The bolt-hole PCD and diameter are also useful if there are no clear markings on the flange you are trying to replace.
