This adapter is used at the hose to filter head connection when installing an oil cooler (or an oil by-pass hose) with the Austin B-series engine (MGA and MGB).

The fine thread on the outboard end is for the AN hose connector. The thread on the engine side (with the seal washer) is a BSP standard thread.

The AHH6701 part number is a similar fitting with bonded seal washer included in assembly. At time of this posting (Feb 2022), most likely the AHH6701 part is no longer available, so use one each ARH1112 seal and ARH1113 adapter (Moss (Motors USA part numbers 324-800 and 435-590).
