Female One Piece Tube Nut - Steel

Female One Piece Tube Nut 

We manufacture these steel tube nuts to suit an AN 37° flare as a one-piece design. To use, simply slide the tube nut over your tube—3/16" for -3 and 1/4" for the -4 version—then flare the tube using a 37° flaring tool. Once flared, you can screw the tube nut onto the appropriate AN male fitting and tighten it. The flare will seat against the inside of the tube nut and the AN flare to create a complete, secure seal.

These tube nuts are made from high-quality steel and are nickel-plated for a tough finish, offering both durability and an attractive appearance.
