I have a Tweco H-20 (or HH-20) from ca. 1975.

Are the parts and consumables (collets, gas nozzles) standard for size 20 torches?

Do I need to know anything else to get the right parts?

They are the same.

You can go HERE and look for CK's Poster Parts, it's a downloaded-able pdf file that shows their torch consumables with part numbers

To be clear:

I need to buy a kit for a WP-20 torch?
