  3. Can these be used in an oxyacetylene torch handle for the valves because of high temperatures.

    1 answer

    1. The UST HNBR O-rings should not be used in an oxyacetylene torch handle, as they are not rated for oxygen service or high-temperature exposure.

      Helpful?

  4. How resistant are these O-rings to ethanol gasoline?

    1 answer

    1. HNBR O-rings offer great resistance to pure gasoline and maintain sealing integrity up to E10, with 5–10% volume swell. However, swell increases to 10–15% at E15 and exceeds 30% at E85, making them suitable only for ethanol blends of 10% or less.

  5. Are these rated for fuel applications. Carbs, fuel lines, etc

    1 answer

    1. The W5201 HNBR O-rings are fuel, oil, and coolant-resistant seals designed for high-temperature, high-stress automotive applications like carburetors and fuel lines.

  6. Can these o-rings be used on high pressure PCP air rifle?

    1 answer

    1. Based on the findings I found from searching online, it appears that a PCP High pressure air rifle works well with a 70 durometer or tensile strength spec’d O-ring. If that is so for your air rifle, then the W5201 kit, item #179212 should work just fine. That’s of course if the correct size is inside the kit.
