Hydraulic Guys - O-ring face seal fittings?

[kstylianos]

I picked up a real nice oil cooler with 'o-ring face seal' fittings. Unfortunately, they are welded to the cooler and I can't swap them out for metric, AN, etc.



I bought the 30mm fittings and oil lines From Chuck (Elephant Racing) that will fit nicely to the hard lines, but can't find any o-ring face seal female fittings with similar barbed ends.



Any thoughts as to where I can get these female fittings, or another possible (inexpensive) solution?

OK. Does anyone know of a good hydraulic shop I call? Thinking an ORFS-metric adapter may work.

Bump for more ideas..

ORFS fittings are pretty standard - Parker and Aeroquip (and others) manufacture a wide range.
Your best bet is to go to their web sites and search for the fitting you need. I have had luck in finding fittings that work with either metric or inch hoses, making the transitions easy.
I am more familiar with parker - they make a wide variety of both inch and metric.
Start here:

once you find what you need then any distributor can get it for you.

Good luck

I would cut them off and weld on what you want.

Thaks for the tip, Bob. Very helpful!

I would cut them off and weld on what you want.

How could you do that w/o dropping filings into the cooler? I had a suggestion of tapping new AN threads as there may be enough material (can just plug up the holes and viola).

Put air into the other fitting while cutting

Charlie:

I'd concurr with Dean.

Cut them off and weld on the correct AN fittings (or metric ones).

If its a used cooler, I'd have it ultrasonically cleaned.

Thanks again, Gentleman. Found a local place that carrys the Parker line and can make hoses on site. May bring the cooler and see what the can do.

I used to see stuff like that on old semiconductor equipment. If memory serves me, they were called VCO fittings. They were replaced by VCR Fittings which used a crush gasket in place of the O-ring. We got ours from Swagelok.

I assume you looked on the non-machined part of the fitting for a manufacturer name?

[kstylianos]

Harry, these are o-ring face seal fittings. The problem is not so much finding a correct fitting for the cooler or 30mm lines, it's that these fittings are used for high pressure (3000 psi) hydraulic applications and the ID of the hoses are not ideal for oil circulation and the crimping sleeves are so long/beefy that once both ends are crimped to the hose, there is absolutely no rubber showing and no flexibility (just need about 9 inches from hard lines to cooler). Anyway, I was looking for the same ORFS end, but with barbed fitting similar to Chuck's 30mm ones above, as they are much shorter, would allow larger ID hose and would get the flexibility I needed.

Diatraibe over, we just cut the threads off and threaded in 3/4" NPT to 16AN fitting. AN is sooo nice but $$

Charlie,

Just trying to help. Glad you found a $olution.

In the future, consider that you only need fittings rated for 150-200 pounds as that is all the pressure you can genrate anyway. They will be more compact and easier to work with.
