Bendix AD-IS Air Dryer Single Assembly, Used

A used Bendix AD-IS air dryer single assembly — the kind of heavy-duty commercial truck component that doesn't come cheap new. The handwritten tag in the photo notes a retail value of $763.96, which tells you something about what you're looking at. The assembly includes the canister, aluminum valve block with marked ports (1 IN, 24, AUX), side-mounted valve with blue cap, and black plastic fittings. Shows typical signs of use — some grime and discoloration on the fittings — but appears structurally intact. Sold as-is; buyer should verify compatibility before bidding.
