PSI - Model WD -Adjustable Rubber Gaskets

SHARE

The  adjustable flange gasket type WD consists of two segments connected by a tongue and groove joint. This allows the two wedge-shaped parts to be turned against each other up to an angle of approx. 8°. After installation, these two parts form a “medium-tight“ bond.

Simple and extremely economical

No need for using wedge disks or additional gaskets

The  PSI Adjustable Flange Gasket Type WD simply and very economically replaces steel or cast iron wedge disks. These heavy wedge disks which are difficult to install also require two additional seals.

The result: Inexact assembly and higher costs. Complicated handling of such metal elements in tight spaces produces uncertainties during installation and increased risk of leakage.

Simple application for misaligned flange faces

Sometimes it is not possible to align flange faces properly. Especially underground pipes with adaptors and flanges, e.g hydrants and valves, cannot always be aligned perfectly.
