Gee that looks just like my picture from the other day

Probably the only thing that might be needed is a new hose since that fitting looks pretty rusty but with a little time and effort I figure it would work just fine..

A standard hydraulic hose would be JIC 37 degrees so, do take the fitting with you to the hose shop for a match..

If you don't know your pressures and temp needs they might sell you a hose that is over kill for your application as some hydraulic applications need to handle over 3,000 PSI.

Bear in mind that the trans fluid goes to a cooler that is make of copper (or brass) and it is only capable of lower pressures. Kinda looks like a brass fitting. And it kinda looks like it only sealed up on the end of the angle. That leads me to think that in fact it was two different angles. Maybe enough torque and it seals up? Not the right thing to do but "maybe" it would work??   Don't jump on me to say it wont work, just my guess as to what may have happened.

For ones that don't understand any of this, like me-

John,
You'll need to purchase a 3/8" pipe tape and make one yourself. With the tap, it's possible you could even clean up the threads on the old one.

Look on Ebay for a tap.

And since I had one of each fitting in my hands, I built a little rig and screwed a B/W trans cooler hose onto each fitting and pressurized each fitting to 150 pounds to do a little real life testing.

Neither one leaked, but the 45 degree SAE fitting had about 50 % more sealing area when I checked the seating surfaces with some prussian blue.

What's all this mean to me?

It means PCM did it right in spite of what Pete might seem to think.

Which means the 45 degree SAE fittings are just fine with the original equipment hoses or if for whatever reason you want JIC 37 degree fittings they'll work too with the original hoses.

You might keep in mind that you can find all kinds of info saying that the 2 different fittings are incompatible.....................but they both sealed in this situation..

I'll keep looking around, most everyone has but not big enough.

Thanks
JT

Ken,
Nice test and thanks. Did you use matching 45 and 37 female hose ends or did you use PCM's 45 on each? That's what started the discussion that the female and males have to match hence the concern. BTW, it's really not my concern nor what I think but some group of engineers called SAE International

KENO wrote: It was the same hose from a B/W transmisssion cooler with a PCM part number. on it.

Since you used the same hose on both fittings, the test is irrelevant. Is the female fitting on the hose a 45 or a 37? Since you got more contact area on the 45 male fitting, I'd say the hose end was also a 45. Only a back yard hack would mismatch fittings!

Yes, I started the discussion out of concern of using proper fittings ether 45's or 37's then you continued with your irrelevant "test" using mismatched fittings. What needs to be explained?

Who really gives a rats @ss what they are if they don't leak in this low pressure situation??
Is an ACBS judge going to deduct points?? How would they determine what was original and how could they tell the angle?? If they had any common sense then they would not even be concerned. Same as another on here should be --unconcerned.
Gosh I hope Spring shows up early this year.

KENO wrote: I guess you just assumed they would use 37 degree JIC fittings without really knowing what you were talking about And the mismatched fittings test was to see what would happen if you screwed the PCM hose on to a JIC fitting.

Ken,
You are correct that I did not know what fittings were used by PCM.

Other than Pete who really cares what the ACBS thinks? It seems to me like Pete has. Museum and he is the curator. These boats are meant to be used and enjoyed not stored in perpetuaty. When you're putting less than 10 hours per year on a boat it's ridiculous but given the desire to live in the great white north somewhat understandable.

It's the CCF reunion's boat show that counts anyway!
