Where this configuration fits

Gauge and test connections support pressure measurement, commissioning and diagnosis. Select them alongside the instrument, isolation arrangement and intended test equipment rather than from fitting appearance alone.

Details to include in your enquiry

State the instrument thread, sealing face and required orientation.
Distinguish a gauge connector from a test coupling with a diagnostic connection.
Confirm the test hose or instrument interface and its permissible pressure.
Choose a straight connector, standpipe, swivel or tee configuration.

Sizes, materials and supplied condition

Specify the tube outside diameter, LL/L/S series, material and every connection. The overall catalogue covers 4–42 mm tube, but an individual configuration may have a narrower range. Carbon steel, 316L and 316Ti can be included in an enquiry, subject to confirmation of the supplied item.

State whether you require complete fittings or bodies only. Include working pressure, peak pressure, temperature, medium and any certificate requirements so the complete assembly can be checked.

Technical selection guides

SELECTION GUIDE

DIN 2353 fitting sizes, series and thread identification

Identify a DIN 2353 connection by tube outside diameter, fitting series, thread and sealing form. A matching thread alone does not establish a correct connection.

SELECTION GUIDE

Selecting materials, seals and pressure capability for DIN 2353 fittings

Select the fitting, tube and seals as one assembly. Pressure capability depends on the exact configuration, material, tube dimensions, temperature and installation method.

SELECTION GUIDE

DIN 2353 fitting installation and inspection overview

Successful cutting-ring connections depend on suitable tubing, matched components, careful preparation and the correct assembly procedure for the supplied fitting system.

Questions answered

How do I specify gauge and instrument connections?

Identify the configuration, tube diameter and series, all connection threads and seals, material, quantity and operating conditions. Send a marked sketch when port positions or different end sizes matter.

Are the catalogue dimensions suitable for final fabrication?

Use them to identify and enquire about the configuration. Obtain the order-specific drawing and confirmed pressure rating before fabrication or installation.
