01-0791 Nordyne BI FLOW DRIER, 3/8" SWEAT FIT

01‑0791 – Nordyne OEM 3/8" Bi‑Flow Filter‑Drier (Sweat Connections)

The Nordyne 01‑0791 is a factory‑specified 3/8" bi‑flow filter‑drier designed for heat‑pump systems requiring refrigerant flow in both directions. With 3/8" sweat connections and a 16" overall length, this drier provides moisture removal, acid absorption, and particulate filtration to protect compressors, TXVs, and reversing valves.

Bi‑flow driers are essential in heat‑pump applications because they maintain proper filtration regardless of refrigerant flow direction. Multiple sellers confirm this part as a genuine Nortek/Nordyne OEM component used across Intertherm, Miller, and Nordyne heat‑pump families.
