LU Brass seal plugs

[hank1995]

I need two 3/8 x 27tpi. I see plenty of taps but no other fasteners much less a plug. Does anyone know of a source? This is for a 1935 Sportfour.

You may want to try Fastenal. They have many fasteners and you can buy small amounts. We have several outlets in our area and Fastenal is in many cities.

If it is a drain plug … STOP ! you most likely have a 1/8 NPT -27 pipe thread. The “T'” stands for tapered. A common 1/8 pipe plug will fit. You may have trouble finding a nice looking slotted pipe plug, if so make one from a common pipe plug. … a little hack saw and file work should do it.

Good hardware stores like Aubuchon have little boxes with assorted screws, nuts and pipe plugs. You can get 1/8 NPT there.

It so happens that Model A Ford uses a slotted brass 1/8 NPT to seal
oil pump hole in block. Part # A 6755 @ 65 cents each.
page 31 of Bert’s Model A Center in Englewood Colorado
Probably shipping would be a tad high for just one itme, but,
it is the right plug

Good catch Louis. Not many would know about that peculiar Model A pipe plug …. your recollection was better than mine.

Home Depot has them in square head. Got a hacksaw?

I had gotten them awhile back on EBAY.

Thanks everyone but it’s 3/8 x 27tpi that I need – not 1/8

1/8″ NPT is a tapered pipe thread. 1/8″ SCH 40 pipe is 0.405″ outside diameter the plug, being tapered and threaded will be in the neighborhood of 3/8″ nominal O.D. I believe that is what you are going for. 3/8″ SCH 40 pipe would have an O.D. of about 0.675″.
