Female One Piece Tube Nut - Steel

We manufacture these steel tube nuts to suit an AN 37° flare, as a one piece tube nut. Simply slide the tube nut over your tube, 3/16" for -3 and 1/4" for the -4 version and flare the tube with a 37° flaring tool. You can now screw the tube not to an apropriate AN male fitting and and tighten, the flare will seat against the inside of the tube nut and the AN flare for a complete seal.

Manufactured from steel and Nickel plated for a tough finish that gives a great look!
