1970-78 Sears- 100 psi twin cylinder Air compressor, with a 12 Gal Tank. Model 106.154540
Sears part supplier (Part's Direct), say's the manufactorer doesn't make these part's anymore, and has no suggestion's on finding replacement's. The part number's they used were, PX-11 Piston Compression Ring's and PX-22 Piston Oil Ring's. I believe the Manufactorer was either, Cerca or Speedair. Any help would be greatly appriciated. Thanks... Jim Brown Jimnycricket38@msn.com
