Supercool OEM approved universal high side in-line filter helps to protect against costly repeat compressor failure. OEM recommended and approved, the single kit fits 5/16 inch, 3/8 inch and 1/2 inch lines. The filter captures residual debris in an A/C system, and can be used as a line splice or repair device for damaged orifice tube holders. Hold any size orifice tube with the included installation clip. Quick and easy leak-free installation requires only 4 inch of straight refrigerant line. The tapered sealing sleeve provides 10 times the sealing area of older filter designs. The shorter filter length with triple the capacity reduces pressure and flow restrictions.
