Where This Part Is Used
Use this straight union connector when building, extending or repairing an Infinity compressed-air piping network. Common environments include automotive service bays, production plants, maintenance shops and metal fabrication facilities.
Installation and Maintenance
Confirm the component model, correct tube outside diameter, available clearance and the system's pressure requirements. Follow manufacturer instructions for insertion, tightening and pipe support. Isolate and depressurize piping before service. Maintain the installation through periodic checks for leakage, damaged supports or disturbed joints.
Recommended Accessories
Coordinate with the appropriate Infinity aluminum tubing, matching union fittings, elbows, tees, ball valves, hangers and assembly tools. Incorrect tube diameter or thread type can prevent a proper seal. Contact Compressed Air Advisors to review a piping layout and complete parts list.

Frequently Asked Questions
What does this Infinity part do?
The 90040-32 is a straight union connector used with compatible Infinity piping components. Check the title, part number and connection size against your planned assembly before ordering.
Will it work with other piping brands?
Compatibility with third-party piping and fittings is not guaranteed. Use matched Infinity components unless the manufacturer explicitly confirms compatibility.
What size should I order?
This listing is identified as 90040-32 and references 32 mm Infinity tubing. Verify actual tube outside diameter and any threaded connection separately, especially when replacing an existing component.
What applications use the Infinity system?
The Infinity product line supports compressed-air distribution in manufacturing, automotive service, fabrication and similar facilities. Certain system components also support vacuum or compatible inert gases as specified by the manufacturer.
What is the maximum pressure rating?
The manufacturer lists an Infinity system rating up to 232 PSI (16 bar) for the corresponding push-in fitting and tube family. The lowest-rated part in the assembled installation governs safe operation.
How should it be installed?
Cut, inspect and deburr tubing, then fully seat the tube in the correct fitting. Follow Aignep's connection-specific tightening, insertion depth, support spacing and safety directions; depressurize the system before modification.
Does this include the rest of the piping system?
No other components are included unless explicitly stated in the selected product's listing. Plan compatible tubing, adapters, elbows, tees, supports, and valves for a complete installation.
Can Compressed Air Advisors help size my air piping?
Yes. Compressed Air Advisors can help evaluate piping diameter, run length, pressure drop and compatible connectors. Share your compressor output and plant layout for assistance.
