Heater Valve Parts

[ckissick]

For my '65/'66 912: Referring to the pic below, I need the rubber washer, second from the right, and the pair of very thin white washers, fourth from right. Where can I get them?

I’m not sure but I don't think you can buy these parts, only a whole assembly. You might be best asking if anyone has a scrap one lying around

That's what I figured. But I may be able to buy something that's close enough to work with minor mods. I need ideas on what type of material to look for that can withstand the heat and not bind while rotating.

stainless for some - you can laser cut some or water jet maybe

or go full nutball with Ti or inconel

Take the rubber grommet and white (nylon?) pieces to an old time plumbing supply or hardware store. Maybe you can match them up.

Those white washers are nylon and very common. You should be able to find them in both metric and SAE sizes from a good industrial supply house -- like McMaster Carr. The same is true for the rubber washers. I have some of both in my hardware inventory and use them for all kinds of things.

You can also make these parts, using a punch and hammer. Punches are also available from an industrial supply house. I have punches from 1/4" up to 1 7/8" and find them very versatile. They will cut through rubber or thin plastic pretty easily.

Get the size punch you need and cut out several plastic circles. To make the center hole you can either punch it out or drill it. When you want to drill through thin materials, like this, be sure to sandwich the part between a same size thicker material, like 1/4" plywood.

Another approach is to use a hole saw, instead of a punch. The advantage here is that you can square up the materials to fit in a drilling vise. Sandwich the nylon (and/or rubber) between two pieces of 1/4" or 3/8" plywood and cut out a rectangular shape, using a band saw, table saw, saber saw, or whatever saw you have.

Secure the sandwich rectangle in a drilling vise and cut out your parts using the correct size hole-saw. Take the circular sandwich you've just created and secure it in the drilling vise. Enlarge the center hole using the proper size twist drill.

For those particular parts, you can probably get away with pretty loose tolerances. If you can't find the perfectly sized hole saw or drill (and/or even if you have to hand sand or file the part) it may not affect the outcome greatly.

Good luck!

The PET lists parts individually but they appear to have been discontinued.

Like others have suggested, I would try a good hardware or industrial supply store for alternative replacement parts.
