Have you tried an auto parts store? Most any NAPA store should have them. While most vehicles use 1/4", they should have 3/8" as well.

I thought those were standard plumbing threads (tapered). Have you looked at your local hardware store in the plumbing department? Think that's where I found mine.

Hope this helps. :coffee:

The 1/4 inch, with a 1/4x3/8 bushing, would work, too.

Brendan, the Greenville NAPA store shows them for $5.67. http://www.napaonline.com/Catalog/Catal ... 0435263502

Take a ride over there and pick one up.

Tractor Supply has them...they are sold as air compressor tank drain valves.

Take the radiator plug out and take it with you to Ace/Home Depot/wherever they have plumbing stuff and just match the size.
