81048 AERCO Boiler and Water Heater Flame Rod Gasket

Normal Stock Item

AERCO 81048 is the OEM Flame Rod Gasket, confirmed by grounded distributor data. It is a small but critical combustion‑seal component used in AERCO boilers and water heaters to ensure accurate flame‑rod operation and prevent air leakage at the flame‑rod port.

AERCO 81048 Flame Rod Gasket — Genuine OEM high‑temperature gasket engineered for AERCO boilers and water heaters. Provides a tight, leak‑free seal around the flame rod to maintain proper combustion conditions, protect the flame‑rectification signal, and prevent nuisance flame‑failure lockouts. Ideal for routine burner maintenance and flame‑rod replacement.

🔧 Core Identity & Function

Part Number: 81048 Component: Flame Rod Gasket OEM: AERCO

This gasket provides the airtight seal between the flame rod and its mounting port. A proper seal prevents combustion‑air bypass, which can weaken flame‑rectification signals and cause nuisance flame‑failure lockouts.

Liberty Supply confirms it is made from high‑temperature, heat‑resistant materials designed to withstand combustion‑chamber conditions.

Furnace Part Source lists it as a brand‑new genuine OEM gasket, shipping same day when in stock.
