If you need to join two male AN fittings, our 131 Series Female Unions are the solution. These fittings are designed differently from others on the market, featuring one solid end with a 37° flare and an internal O-ring seal, along with a swivel nut on the other end. This unique design ensures the fitting is both stronger and more compact, crucial for tight spaces and secure connections.

We also offer stepped-size versions for added versatility.

Manufactured from premium 6061-T6 billet aluminium and hard anodised for superior durability and finish, our 131 Series adapters are built to meet the highest performance standards.
