Joint washer (99-0514)
Joint washer/gasket that seals the float bowl on an Amal Concentric carburetor, PN 622/073 (formerly 99-0514).
This is the joint washer that seals the float bowl on an Amal Concentric carburetor, part number 622/073, listed under the older number 99-0514 in earlier parts books. It sits between the float bowl and the carburetor body, keeping fuel from seeping out at that joint.

It shows up across a wide run of catalog listings tied to Amal Concentric carbs on unit-construction Triumph twins from the late 1960s into the mid 1970s, including entries alongside T90, T100, T100C, T100T, T100R, TR6R, TR6C, T120R, and T140V carburetor figures. If your float bowl is weeping fuel or you're rebuilding the carb, this is a cheap item to replace as a matter of course.
Because the same Amal Concentric carb body was used across a lot of different Triumph, BSA, and Norton models, this gasket turns up in plenty of unrelated parts books under the same number. Worth keeping a couple on hand if you're doing carb work, since they're easy to tear on removal.
