If you need to join two male AN fittings together, these are what you need. Speedflow make their female unions slightly different to others, with one solid end with the 37° flare and an internal O-ring seal and one swivel nut. This makes the fitting stronger and shorter, which is so important when joining components together.
The 131 Series adapters are made from quality 6061-T6 billet aluminium and hard anodised to give you the best quality fittings available!
