Connect instrument tubing to an equipment interface with the tube size, port geometry and operating conditions clearly defined.
Concept illustration. Configuration subject to engineering review.
Specify the tube outside diameter and tube-side design first, then confirm the equipment port and assembly requirements.

A buyer questionnaire for engineering review; final specifications require approval.
Metric or fractional; give exact OD
Specify approved connection design and mating tube material
Thread, port, seal seat and installation length
Medium, pressure, temperature and cleanliness requirement
Confirm requested grade and compatibility
Body only or complete assembly; test plan to be agreed
Final dimensions, material, fit and performance are confirmed against the approved drawing and operating conditions.
Retain the approved tube-side interface where required; review different instrument-side ports, body length, wrench features or mounting geometry.
Provide the existing standard or approved mating drawing. Interface compatibility must be confirmed.
Retain the approved tube-side interface where required; review different instrument-side ports, body length, wrench features or mounting geometry.
Instrument fitting bodies, sensor adapters, small threaded components and mating port parts can be quoted from an agreed drawing.

Need drawing review? Explore our engineering support.
List critical dimensions, fit and seal surfaces, material documentation and any assembly or test requirements in your RFQ. The inspection and test scope will be agreed for the approved design.
Give the exact outside diameter and whether the dimension is metric or fractional. Include tube material and wall thickness where they affect the selected connection design.
State whether you need the machined body only or a complete assembly. Components, assembly method and validation requirements must be agreed before a supply commitment.
Interchangeability is not assumed. Send the interface drawings and any required approval or compatibility tests for engineering review.
Product family: Instrumentation Tube Fittings
Include the mating interface, quantity, requested material and operating conditions in Project Details. Attach your drawing or the completed specification request sheet.
