Bell Gossett Bg 113041 Drain-o-tank Air Charger

Product Description

The BELL GOSSETT BG 113041 is a Drain-O-Tank Air Charger designed to recharge waterlogged compression tanks in hydronic heating systems. When a compression tank becomes waterlogged, system pressure fluctuates and heating performance degrades. This tool provides a fast, reliable method to restore the proper air charge without draining the entire system. It connects via a 1/2-inch MNPT fitting, handles working pressures up to 125 psi, and is rated for temperatures up to 240 degrees F. HVAC technicians and plumbers servicing hot water heating systems keep this tool on hand for routine service calls.

The BG 113041 is intended for use on residential and light commercial hydronic heating systems equipped with steel compression tanks. It is applied during system maintenance when a tank has lost its air charge and is causing pressure irregularities, short-cycling on the pressure relief valve, or inconsistent system operation. The tool threads directly into the tank service port and allows the technician to recharge the tank air side quickly and accurately on-site.

Key Features

• Recharges waterlogged steel compression tanks without full system drain-down
• 1/2-inch MNPT connection for direct tank port access
• Rated to 125 psi working pressure
• Maximum operating temperature of 240 degrees F
• Suited for hydronic heating system service and maintenance

Compatibility

Designed for use with steel compression tanks in hydronic heating systems requiring air recharge service through a 1/2-inch MNPT service port.

Installation Notes

This tool is typically used by licensed HVAC technicians or plumbers during hydronic system service. Before connecting, relieve system pressure and confirm the tank service port is accessible and free of obstruction. Thread the 1/2-inch MNPT fitting into the tank port by hand before applying tool torque to avoid cross-threading. Follow applicable mechanical codes and system manufacturer procedures when servicing pressurized hydronic equipment.
