Stainless Steel Adaptors

Stainless Steel Adaptors are used to connect pressure gauges, isolation valves and related pressure gauge accessories where thread compatibility or installation layout needs to be matched.

This range includes adaptor fittings for industrial pressure measurement applications, with BSP and NPT options available depending on the product. Select by thread form, material suitability, sealing method, process media and working conditions.

Stainless gauge adaptor fittings

Stainless Steel Adaptors are used to connect pressure gauges, valves and associated pressure measurement accessories where thread form, connection orientation or installation layout needs to be matched. They are commonly selected for industrial gauge installations where a durable metallic fitting is required between the instrument and the process connection.

These gauge adaptors may be used with BSP and NPT threaded connections, depending on the specific product and application. Correct thread identification is essential, as BSP and NPT are not directly interchangeable without the appropriate adaptor arrangement.

Stainless steel is often chosen where the working environment, washdown conditions or process exposure may require improved corrosion resistance compared with some alternative materials. Compatibility should always be checked against the process media, pressure, temperature and installation conditions.

For replacement accessories, OEM equipment or maintenance stock, confirm the gauge connection, process thread, sealing method and required orientation before ordering. Selecting the correct fitting supports reliable local pressure indication and helps avoid installation issues during commissioning or service work.

BSP and NPT options

Adaptor fittings can help connect pressure gauges and accessories where BSP or NPT threaded connections are required. Always match the thread form and sealing method to the instrument and process connection.

Stainless steel construction

Stainless steel adaptors are commonly used where corrosion resistance, durability and industrial service conditions are key selection factors. Suitability depends on the media, temperature and operating environment.

Installation compatibility

The correct adaptor supports a secure gauge installation by matching connection type, layout and orientation. This is important for replacement work, panel builds, OEM assemblies and site maintenance.

Typical adaptor applications

Stainless steel gauge adaptors are used across industrial pressure measurement installations where connection compatibility, service access and material selection matter.

Pressure gauge installation

Used to connect pressure gauges to process lines, manifolds, isolation valves or other pressure gauge fittings when the thread form or connection layout needs adapting.

Maintenance replacement

Suitable for maintenance teams replacing damaged, worn or incompatible gauge fittings during routine service, shutdown work or instrument changes.

OEM equipment builds

Used by OEMs and panel builders to standardise pressure instrument connections across machinery, skids and packaged process equipment.

Industrial process systems

Applied in process environments where stainless steel may be preferred for durability and resistance to external conditions, subject to media and duty compatibility.

How to choose adaptors

Select stainless steel adaptor fittings by matching the connection requirements of the gauge, process connection and any accessories fitted in the pressure measurement line.

Confirm thread type

Identify whether the gauge and process connections are BSP, NPT or another thread form. Do not assume similar-looking threads are compatible without checking.

Check material suitability

Choose stainless steel where the application calls for a robust metallic fitting, but confirm compatibility with the process media, surrounding environment and cleaning conditions.

Review installation layout

Consider whether the adaptor needs to connect directly to a gauge, isolation valve, syphon, snubber or mounting arrangement, and check that the orientation allows safe reading and access.

Match duty conditions

Ensure the selected fitting is appropriate for the application duty, including pressure, temperature, vibration, pulsation and any sealing requirements stated for the installation.

Adaptor fitting FAQs

These FAQs cover common selection points for stainless steel pressure gauge adaptors used in industrial installations and replacement work.

Can BSP and NPT threads be connected directly?

BSP and NPT are different thread forms and should not be treated as interchangeable. Use the correct adaptor for the gauge and process connection to avoid poor sealing or thread damage.

When should I choose stainless steel adaptors?

Stainless steel adaptors are often selected where a durable fitting is required or where external corrosion resistance is a consideration. Always confirm suitability for the process media and duty conditions.

Are these adaptors suitable for all pressure gauges?

No adaptor should be assumed suitable for every gauge. Check the gauge thread, process connection, sealing method, pressure duty and installation layout before selecting a fitting.

Can adaptor fittings be used with isolation valves or snubbers?

Yes, adaptors are often used with isolation valves, snubbers, syphons and other pressure measurement accessories where compatible threads and installation conditions are confirmed.
