Aeroflow -6AN to 3/8" Aluminium Tube Nut - Black Finish (AF818-06BLK)

Aeroflow Performance Tube Nut & Tube Sleeves help attach steel or aluminium hardline to a 37-degree AN fitting. When a flexible hose assembly doesn't work in an application or rules prohibit it, tube nuts and sleeves helpfabricate a hard line for connection to AN style fittings and adapters. The flare tool required for this is sold separately (AF98-2048).

Both the tube nut (AF818 series) and tube sleeve (AF819 series) must be used in conjunction with each other in order for them to work. Slip the Tube Nut onto the hard line first, followed by the Tube Sleeve. Then use a 37° flaring tool to flare the end of the tubing. When you screw the Tube Nut onto a male AN fitting, the Tube Sleeve will protect the end of your hard line.

Made from either billet 6061-T6 aluminium or 304 stainless steel and anodised either blue, black and silver finish for the billet aluminium. Available insizes from -3AN up to -16AN and suits hard line from 3/16" (4.7mm) up to 1" (25mm).
