Somebody was asking about part numbers of the simple parts on the SN Paxtons.
Following is what I have discovered about my SN89:
Florocarbon (rear) seal: TCM 2771500
Front seal: NATIONAL 450163
Case to Case 'O' Rings (2 req'd): AS568A-261
MCMASTER-CARR #9464K559 (1 PACK) - VITON
Dip Stick 'O' Ring: AS568A-011
MCMASTER-CARR #9464K16 (PACK CONTAINS 100) - VITON

If anybody has the part number to the front seal on a SN93 please post it.
Just a note regarding McMaster-Carr and Canadian customers...
For some reason, McMaster-Carr no longer ships to Canada (they do still supply some of their larger long-term Canadian clients, but they are no longer accept new orders shipping to Canada).
However, all isn't lost for Canadians in need of new 'O'-Ring seals for their Paxton ball-drive blowers. Acklands-Grainger (a Canadian industrial parts and equipment supplier similar to McMaster-Carr) carries these 'O'-Ring seals, and their prices are extremely reasonable. Below are the Acklands-Grainger part numbers for the 'O'-Ring seals:
Case-to-Case 'O'-Rings:
Acklands-Grainger #HBS568-261 (5 pack*) - Hercules Sealing Products
Dip Stick 'O' Ring:
Acklands-Grainger #HBS568-011EP (12 pack*) - Hercules Sealing Products
*different quantities of each type are available
