I am looking for at least four compression fittings. These much be for 1/2" ID, 3/4" OD tubing, and need to be in great shape. I do not want anything that is scratched up or has dry-rotted O-rings. LMK your price shipped in the US and your heat, plus pics of the fittings please. My heat is flawless under t_ski (380-0-0).
