Brass Compression Fitting For Plastic, Copper, & Aluminum Tubing, 0.19 Inch Tube OD To 1/8-27 Male NPT, Straight

This fitting is designed for use with plastic, copper, or aluminum tubing, offering versatility in your connection options.

Plastic, copper, and aluminum tubing all work with this fitting, so you're covered on both ends of your setup. The tube OD needs to be 0.1875 inches and the thread is 1/8-27 male NPT. One thing worth knowing on the plastic side: the temperature range depends on whatever tubing you're using, so check the tubing's own specs rather than assuming it matches the metal range. For metal tubing, the fitting handles from negative 65 up to 250 degrees F.
