Question:

Hello, Concerning Flair-It PEX 90-Degree Elbow Fitting - 1/2inch Barb x 1/2inch Barb Item # FL89VR I read that it is for 1/2inch inner diameter tubing. What outer diameters fits? My camper trailer’s existing braided vinyl tubing appears to be 1/2” ID with 5/8” OD. My replacement braided vinyl tubing is 1/2” ID with 3/4inch OD. I am trying to discern if item #FL89VR will correctly connect the two. Thanks

Expert Reply:

The Flair-It PEX 90-Degree Elbow Fitting # FL89VR is designed to work with tubing with a 5/8" (0.625") outer diameter. So it will work with the trailers existing braided vinyl tubing, but not with the 3/4" OD replacement tubing.
