Seal & Media Compatibility Finder
ReelcraftLook up which o-ring / seal material tends to work well with a given fluid, gas, or chemical — or browse everything a given seal material handles well. Suggestions below are based on Reelcraft’s laboratory compatibility research (Tech Bulletin TB0002, full PDF), not a guaranteed specification — see the notes below each result.

HNBR is now standard on most Reelcraft swivels. When it isn’t a good fit for your media — rated Doubtful, Unsatisfactory, or No data below — Reelcraft also sells replacement seal kits in Buna-N, FKM (Viton), and Aflas so you can fit the right seal to your application. If you are still unsure about your application, contact Reelcraft Customer Service at 1-855-634-9109 with your specific reel model and application.
2,000+ media entries from Reelcraft's lab-tested compatibility chart.
Pick a seal material to see which media it's rated satisfactory or fair for.
1 — Satisfactory
2 — Fair (usually OK static)
3 — Doubtful (sometimes OK static)
4 — Unsatisfactory
X — Insufficient data
Every rating and suggestion on this page is a research-based starting point drawn from laboratory testing on pure substances at room temperature (72°F) — it is not a certified specification or a guarantee of performance in your specific application. Real-world results vary with temperature, pressure, concentration, and use. Butadiene, Isoprene, Natural Rubber and Hypalon are shown for reference only — Parker does not manufacture o-rings in these compounds. Fluorosilicone and Silicone ratings apply to static seals only. HNBR temperature range reflects Reelcraft-tested figures for swivel seals and may differ from general HNBR industry literature. Always confirm critical, high-pressure, or temperature-extreme applications with Reelcraft engineering before final material selection.
