Frequently Asked Questions
What is a global-thread swivel?
It is a captive-nut thread that seals on an O-ring or cone and lets the fitting rotate, so you can align tubing without over-tightening.
Can I position the elbow after tightening?
Yes. The swivel design lets you aim the tube port after the thread is snug.
What tubing does the 5/16 in. port accept?
It accepts 5/16 in. OD tubing rated for your line pressure and temperature.
