Aeroquip fittings

[Denys Jones]

Does anyone here have a catalogue (or other publication) on Aeroquip couplings of WW2.

I'm trying to get a handle on a coupling used in the brake lines of Lockheed Hudson/Lodestar aircraft. Lockheed refer to it in the parts book as "Coupling self sealing" and give it a part number of 104-L (667236) and is item 31 on the attached image.

I need a reliable detailed illustration of it so I can sort through our stocks of likely candidates for NZ2035.

Perhaps MiTasol knows.

Hi Denys

I gave away all my old Aeroquip manuals years ago but the person is still alive so I will contact him and post any results here for all to see.

Here's the webpage for the current stuff...

There are a couple of other lines they have, but that should be enough to get you started. You might also get in touch with Taigh Raimey over at Fort Stockton and see if they still have them on their aircraft and can get you an Aeroquip number off of them.

As luck would have it last night I opened a box of books that included Lockheed Standards/Specs. Naturally they did not include the part Denys wants but I started a thread for them and the Vultee and Bristol?/British? specs I have. I also have some cross references from manufacturers numbers to standard AN numbers.

Aircraft manufacturers standard parts

MOst, if not all, aircraft manufacturers had the internal specifications for standard parts including, in many cases common parts like nuts bolts and fittings. Some manufacturers used industry standard parts like AC and AN parts. Some used a mix. My first post is Lockheed Specs. I bought...

I have not found any more yet but here is a Douglas drawing for a similar item. It is highly likely, but not guaranteed, that both Douglas and Lockheed were using the same Aeroquip fittings.

The mating part should be same p/n +-1.

EDIT - I just saw the ball diameter and it is way too big for a brake line.
