Sturdy carbon steel fittings provide good wear resistance in demanding applications where corrosion is not a concern. They are single-ferrule fittings, also known as CPI.
Instrumentation fittings are held to stricter tolerances than standard compression fittings and do not require welding, flaring, or any other tube preparation to install, reducing installation time and maintenance costs. They consist of a body, nut, and sleeve (or ferrule). The sleeve compresses against the tubing as the nut is tightened to form a tight seal. For use with hard plastic or metal tubing.
Join tubing running in the same direction with these fittings.
Use these fittings to connect threaded pipe or fittings to tubing in a straight line.
90° Union Elbows
Connect tubing at a 90° angle with these union elbows. They have tubing connections on both ends.
Make a sharp 90° change in the direction of your tubing with these 90° elbows. They have a threaded connection on one end and a tubing connection on the other.
Merge two lines or split a single line into two with these union tee fittings. They have tubing connections on all ports.
Create a 90° branch to send flow into two tubing lines or to join flow from two tubing lines. Run tees have a tubing connection in the middle set at a 90° angle to a threaded connection on one end and a tubing connection on the other.
Combine two lines into one or split a single line into two with these tees. They have a threaded middle port set at a 90° angle to a tubing connection on either end.
Stop or direct the flow of material in your tubing system and protect external threads on fitting heads using these caps.
Insert these plugs into fittings or tube ends to close them off and seal out dirt and contaminants.
Secure fittings to tubing with these nuts.
Use ferrules to get a tight seal when installing a fitting onto a length of tubing.
