Stainless Steel Instrumentation Tube Fittings

Stainless Steel Instrumentation Tube Fittings

Fittings made from stainless steel have a corrosion-resistant surface that protects the material from environmental contaminants, even if scratched. They are suitable for use in harsh environments or for transferring corrosive liquids or non-potable water. Choose between single-ferrule and double-ferrule fittings. Although they can be used interchangeably, single-ferrule fittings (also known as CPI) are well suited for general-purpose applications. Double-ferrule fittings (also known as A-Lok) offer a more secure hold at higher pressures and are compatible with Swagelok, Let-Lok, and Yor-Lok fittings.

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.

Unions

Join tubing running in the same direction with these fittings.

Tube-End Reducers

Connect tubing using these reducers, which have a tube stem on one end and an instrumentation fitting connection on the other.

90° Union Elbows

Change the direction of your tubing with these 90° union elbows. They have tubing connections on both ends.

90° Elbows

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.

Male Connection

Female Connection

45° Elbows

Redirect tubing at a 45° angle with these elbows, which have a threaded connection on one end and a tubing connection on the other. They restrict flow less than 90° elbows to minimize pressure loss.

Union Tees

Merge two lines or split a single line into two with these union tee fittings. They have tubing connections on all ports.

Run Tees

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.

Female Run Tee

Branch Tees

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.

Crosses

Also known as four-way fittings, crosses redirect flow at 90° angles by branching one inlet into three outlets or vice versa.

Caps

Stop or direct the flow of material in your tubing system and protect external threads on fitting heads using these caps.

Plugs

Insert these plugs into fittings or tube ends to close them off and seal out dirt and contaminants.

Nuts

Secure fittings to tubing with these nuts.

Ferrules

Use ferrules to get a tight seal when installing a fitting onto a length of tubing.

Single Ferrule

Front Ferrule

Back Ferrule

Ferrule Sets

Tube Inserts

Strengthen and reinforce tubing ends with these inserts so they maintain their shape while installing fittings. Also known as compression inserts.
