PO2 schrader valve stem extension question

[Joseph H.]

Can someone post a pic of an original valve stem extension for use with PO2 hubcaps. Thanks,
the valve stems should be TR413, 1 1/4 in, but what is the length of the extension? 1"?
Thanks,
Joe

Re: PO2 schrader valve stem extension question

I don't have one to check (I am so thankful for that you can't imagine.) but from what you have posted I would expect the installed extension to increase the total length of the valve stem by 1 1/4-inches. I know the 1970-72 TIM&JG gives the installed length of the valve stem, so add 1 1/4-inches to that and you have the total installed length. Or am I missing something? I have a feeling I must be.

Re: PO2 schrader valve stem extension question

The JG does not indicate the overall length, just the length of the valve stem(1.3 inches). Also, that a schrader extension was used for the PO2, but
nothing about the length of the extension or again nothing about total length(stem and extension).

I'm not home to measure these but will be this weekend. They came in a manila envelope marked Deluxe.

Sorry Joe; I misunderstood your question. Reading comprehension is not going so well for me this Monday.

This is Ralph Spear's story:


"Terrry, They say schrader 12 USA on them"


My suspicion is the number 12 in Ralph's post and Mark's number 17 are mould numbers and there are likely other valid numbers to be had.

Mark,
Thanks...........Terry also.
So, I think I can get the valve stems, but not sure where to get the correct valve extensions.

So, your computer is working on the beach.....

Who sells these ? I need a set for my 70 454 with PO2's.

Re: PO2 schrader valve stem extension question

The Schraders are gonna be a tough score. Last set I saw sell, went for 400+. There is another design that is sold in reproduction with a round tip. I'm sure all the vendors sell them.
