Your specification

Configure your product requirement

Enter the capacity and site requirements you need. Your selections carry into the RFQ and remain editable before submission.

Essential operating requirements

Select a documented reference, or leave blank and describe an unlisted requirement. Reference ratings remain separate from your requested specification.

Additional dimensions and application details
Equipment identification & spare parts

Identify the installed equipment and the part you need. Add nameplate photos, drawings or a parts-list extract in the RFQ attachments step.

Next: contact details, quantity and delivery. Leave unknown requirements blank and request help in the RFQ.

Applications

Connections for pneumatic tube circuits and machine air distribution.

Selection guidance

Documented tube ODs here are 4, 6, 8, 10, 12, 14 and 16 mm. Specify both tube OD and thread; include elbow, tee, union, bulkhead, reducer or swivel form when a straight fitting does not suit the installation. Those other forms require separate source selection.

Technical notes

Tube OD is not thread size or tube ID. G/BSPP, R/BSPT, NPT and metric threads must be identified correctly. The fitting envelope is not a blanket tube rating, and fitting/tube compatibility is confirmed for the actual materials and conditions.
