11-A Distributor Thread Size I have a stripped thread on a distributor I am overhauling. What is the thread size of the vacuum connection?

Re: 11-A Distributor Thread Size 3/8 -24 UNF. 99% sure can anyone confirm?
|
Re: 11-A Distributor Thread Size NO expert BUT being a brass fitting/tube wouldn't it be a "NPT" or a National Pipe Thread because "Machine" threads do not "seal" so you couldn't seal the "vacuum" with a machine thread!!! MY "guess" would be a 1/8th NPT or 1/8 National Tapered Pipe Thread!!! AS I said....MY GUESS

Re: 11-A Distributor Thread Size Rock, no, mate, I just went and checked, it is the fitting for a 3/16 tube, which is 3/8-24 UNF.
A 3/8-24 tap screws in nicely but a 1/8 NPT barely starts and goes tight straight away. It was late when I posted last night, but was able to do a physical check today. The nut has a tapered end which bites into the pipe. Mart. |
Re: 11-A Distributor Thread Size If you've stripped it, you could go 1/8 NPT and use an adaptor to get back to 3/16 tube.

Re: 11-A Distributor Thread Size That was Ford's original compression fitting that was used clear up into the 60s at least.

Re: 11-A Distributor Thread Size I've always known them as "Ford Nuts".:)

Re: 11-A Distributor Thread Size Ya, I would really think hard about any attempt to tap it out to a different size, could really open up a can of worms.

Re: 11-A Distributor Thread Size Ford used a lot of unusual thread sizes and pitches. At our shop we aways save any "left over" nuts and bolts. We have several coffee cans of them, and have been glad we did.

Re: 11-A Distributor Thread Size Thank you to all who replied. I have now re cut the thread back to 3/8”x24 UNF, not perfect but with thread sealant it will be OK. Best regards Roger.
