Dan,
Which metric fittings? Are you looking for the thread size callouts on numbers:
16, 12, 10, and 8? These are the common designations found on the CJ.

| Subject: | Re: Flow Restrictors |
On this same topic, I removed the six air fittings from the rear gear handle and
noticed that a flow restrictor fell to the floor of the cockpit. Which line
did it come from? In the diagram I note a restrictor on the line that goes to
the NLG actuator. Is that the one?
Thanks, Gil

How does the oil cooler come out? It seems that it is lodged between the ducts
on either side which look to be riveted in place!

Bill;
I have no direct experience with the Yak 52 tube fittings but am near
certain they are identical to the CJ. Someone please correct me if that
is not so.
The following is based on that assumption.
The flare angle is the aviation standard of 37 degs. which is also true
of all AN and MS hardware for =9Cflare type=9D tube fittings
(there is also an MS compression type).
If tube/pipe (rather than tube/tube) the pipe thread is universal. On
the small 6 mm tube fitting it is 1/8=9D pipe thread. The same as
AN, MS and SAE fittings.
The tube end thread is metric but, like SAE thread, there are coarse,
fine and very fine variants.
The Chinese utilized Russian thread standards (why I assume the CJ and
Yak are the same in this area). But I believe that Russia (and Eastern
Europe?) used a different thread pitch for this purpose than Western
Europe.
It is possible to mix and match fittings, tubing and =9CB=9D
nuts (with varying degree of complexity) utilizing AN and
Chinese/Russian in the 6 and 8 mm tube sizes. Not too likely in the 10
and 14 mm sizes.
It is quite possible that some Yak/CJ owners have used SAE fittings
rather than AN standard assuming they are physically the same due same
thread on both ends. Where SAE differs is the tube flare. It is 45
degs. (90 degs in SAE parlance) NOT the aviation standard of 37 degs.
Hope that helps a bit.
Walt

Try a tractor supply, many of the new tractors (foreign ones) are now
metric. May or may not be the same.
