Brass Compression Fitting, 0.38 Inch Tube OD Run & Branch To 0.38 Inch Male NPT Run, Tee

Plastic tubing does need a little extra attention with this one. An Eaton PT230 insert is recommended when running plastic tubing through the fitting. Without it, the compression may not seat correctly against the softer tube wall. Also worth keeping in mind that plastic tubing has its own temperature limits, and those limits take priority over the fitting's rated range, so make sure whatever plastic tubing you're using is rated for the conditions you're running.

This fitting is suitable for use with aluminum, copper, and plastic tubing. For plastic tubing applications, an Eaton PT230 insert might be needed. Just remember that the plastic tubing's temperature range shouldn't be exceeded.
