Here in alaska we purchased American Fittings' (a New Jersey Co.) 1/2 inch EMT connectors for $68 for 50 each. The made in China fittings that were of better quality were $20 for 50 each. The made in America fittings cannot be installed with 430 Channelocks without disassembling the connector because there is not enough metal between the nut and the compression ring. Additonally, it took over an hour to find the made in American fittings since only one company makes them.
My question is: I understand there is a Department of Defense Policy letter to the edffect that if made in America fittings cost over twice the Made in China fittings then the Made in China fittings can be used. Is this true and what is the number of the policy letter?
