Thank you for your reply. We have already done it. The manufacutre is no longer Teledyne Continental is L-3 Communication (CPS).
The vendor did advise us with regards to one supplier. We are looking for more potential suppliers in order to preform a competition. If you have any recommendation other than Niagara, I would be more than happy to hear.
We manufacture oil coolers in Wisconsin. Thermal Transfer Products in Racine, WI. Depending on what you need, we may be able to do it, or point you in the right direction.
My organization would be willing to do business with a U.S Vendor that has the component Oil Collers manufactrured outside of the U.S if it will be cost efficient compare to U.S manufacture that manufacture in the U.S.
