Choosing pressure gauge flanges and clamps

Front flanges, back flanges and panel clamps provide different ways to secure a gauge. Choose the arrangement around the panel or support surface, then check how the part attaches to the instrument.

Case diameter is a starting point, but fixing centres, attachment features and clearance determine whether a mounting part will fit.

Browse all pressure gauge accessories or contact GNW for help matching the part to your installation.

Checking the installation

Measure the panel opening and available depth before ordering. Leave space for the pressure connection and any tools needed for fitting.

When replacing a flange or clamp, compare the fixing details rather than relying on the nominal gauge diameter.

Front flanges

Check the gauge and panel dimensions for the required front mounting.

Back flanges

Use compatible parts for the intended surface-mounting arrangement.

Panel clamps

Match the clamp to the gauge case and panel requirements.

Applications

Pressure Gauge Mounting Flanges and Clamps can support the following tasks when selected for the duty.

Control panels

Secure a gauge in an appropriate panel opening.

Equipment mounting

Position an instrument on a suitable machine structure or support.

Replacement hardware

Match an existing mounting part's attachment and fixing dimensions.

Maintenance access

Allow room behind and around the gauge for connection and removal.

How to choose

identify the mounting type; match the gauge case; check fixing dimensions; allow working clearance.

Identify the mounting type

Choose front flange, back flange or clamp to suit the layout.

Match the gauge case

Confirm model, diameter and attachment features.

Check fixing dimensions

Measure the panel opening, fixing centres and any relevant thickness limits.

Allow working clearance

Leave access to the connection without straining the gauge or pipework.

Frequently asked questions

Practical answers to help with selection and replacement.

Are mounting parts universal?

No. Gauges of the same diameter can have different cases and attachment features.

Which dimensions should I check?

Check the case diameter, fixing centres, panel opening and available depth.

Will a flange change the gauge accuracy?

No. It is a mounting component and does not change the stated accuracy or environmental rating.

Can GNW help identify a replacement?

Send the gauge model, photographs and the mounting dimensions.
