ASME Propane Tank Fill Valve Replacement for YSN122LB, YSN203 & YSN29.3 Tanks

Replacement Fill Valve designed for ASME propane tanks, including models YSN122LB, YSN203, and YSN29.3. This valve is engineered with an integrated float mechanism that helps prevent overfilling during the propane filling process by limiting the tank fill level to approximately 80% capacity. Maintaining proper fill levels allows safe vapor expansion when temperatures rise, helping improve tank safety and performance.

Constructed from durable brass components for long-lasting reliability and corrosion resistance, this fill valve is suitable for RV, motorhome, and permanently mounted ASME propane tank applications. Precision-machined fittings provide a secure connection and dependable operation during refilling.
