Stainless Steel Swagelok Tube Fitting, Union, 3/4 in. Tube OD

Joining 3/4 in. tube is heavy work, and a bad connection at this size fails loudly. The Swagelok SS-1210-6 union ties two 3/4 in. tube runs together with a genuine Swagelok two-ferrule end on each side, machined in 316 stainless steel.

At 3/4 in. the tube carries real force, so the back ferrule matters more than ever. It grips and supports the tube while the front ferrule handles the seal, which keeps make-up torque out of the tubing and stops the line from working loose under vibration. Gaugeable pull-up lets your crew verify the joint instead of trusting feel.

Use it to splice a damaged run, tie in a skid, or close a loop during a turnaround. Collins-Oliver stocks the large sizes most distributors make you wait on. Call (800) 247-5756.
