Brass Sleeves

Brass compression sleeves (ferrules) for compression fittings: lead-free sleeves, NAB sleeves for nylon air brake tube, MAF/USA self-align sleeves and lead-free compression sleeves. The sleeve is what the nut crushes onto the tube to make the seal, so it has to match the fitting system and tube size. Sleeves are single-use once compressed.

Each listing groups the stocked part numbers for one style. Choose size and thread on the product page.
