Hi All. Would anyone know where I can find these types of anti-isolation grommets please? I require three for the tuning unit of my AWA Radiola 540-MA 5 valve radio. I have tried many places but nothing like it yet. Photos attached.
The dimensions are to fit a:
3/8' hole, (10mm)
1/16th" (1.3mm) plate,
OSD 5/8" (15mm),
ISD 1/4" (6mm)

One end has an insert for a washer to mount the grommet/bush.

Thanks.

My first place to look would be an auto parts supplier such as Repco or Supercheap. They usually have a range of grommets. Failing that try Ebay. Vintage radio parts suppliers also carry them - search the internet eg https://antiqueradio.org/parts.htm

I know from experience getting the exact sizes is difficult - some compromise requiring packing or trimming might be needed.

Clark Rubber. They have a huge range of these things in stock (or at least the Brookvale store does)

Jaycar stocks grommets in two sizes.

I still use these when restoring a radio for the power cord and prefer them over the cable glands for originality. There's no reason why these can't be used for tuning condensers and they can be trimmed for fit with a stanley knife, if needed.

Bunnings &Engineering supplies have. Used recently on Howard tuning gang.

Glands have superior holding power. I use them pointy end into the pan & often put a zip tie on them to ensure they cannot be pulled out.
