Description:
🧰 AG‑144 — HEATER CONTROL VALVE / SERVICE CORE — SPECIFICATIONS & CROSS‑REFERENCE
AG‑144 appears in your inventory as part of the AmGauge / Everhot / Murray heater‑control‑valve family. This one is not a full valve body — it’s a service‑grade internal valve core assembly, used to rebuild several AG‑series heater control valves.
Your box label shows:
AG‑144 — EVERHOT H‑2006 — MURRAY 27‑7601 / 27‑7613
That places it squarely in the internal rebuild kit category.
