Description
The Maxitrol 13A31‑50 Vent Protector is a rugged, outdoor-rated accessory that safeguards gas regulator vent ports from environmental contaminants. Designed specifically for 3/8″ NPT vents, it is compatible with Maxitrol 325‑5, 325‑5L, RV81, and 210D regulators. This vent protector helps block rain, snow, insects, dust, and debris from entering the breather hole—without functioning as a vent limiting device.
