O-Ring Manufacturers


  • Apple Rubber - Rubber Seals, and O-Rings. I'm not sure about this company. I asked for a quote on a 24x1mm O-ring and they quoted me 21.8 cents in quantity 10,000. Given that it was 10 times what it should be, I thought it was an error, but they confirmed that it was correct. I was able to buy the same o-ring at a local industrial supply store for 22 cents in quanity 1. Who knows perhaps they gold plate their O-Rings:) Anyhow, I'll be looking elsewhere.
  • Metro Industries - This friendly company actually lists prices on its web site. You can order in small or large quantity.
  • Seastrom - Lots of metal stampings, custom washers, hardware, o-rings, clamps and brackets.
  • Small Parts - Lots of weird hard to find parts, and tubing.
