1950s A/C O Rings

[Bob Kielar]

Looked on the forum trying to find the correct size O rings that go on the a/c manifold to the A-5 compressor for my 55 Fleetwood. Does anyone know the correct size and color do they have to be green?

Thanks,
Bob

This is the size I found that fits. There HNBR O Ring green in color #A211 O Ring ID 13/16" OD 1-1/16" thickness 1/8" Purchased them from Harbor Freight Store here in Janesville Wi. 205 piece set for $11.00. Just thought I'd pass this information along for future use.

Keep Cruzin,

I think the GREEN colored A/C o'rings are more modern for R134-A and newer refrigerant (can be used on R-12 systems)
