Conbraco

Conbraco Industries, the company behind the Apollo valve line, is a manufacturer of brass and bronze valves and flow control products based in Matthews, North Carolina. Its liquid level sight gauges let an operator see the water or process level in a boiler, tank or vessel through a glass. A valve at each end isolates the glass for service.

BoilerSupplies.com carries the Conbraco 20-series, 23-series and 24-series liquid level sight gauges and the parts that keep them in service. Those parts are the repair kits, Viton and TFE with Hypalon gauge glass washers, valve stem packing for Conbraco water gauges, and copper, stainless steel and brass protection rods. The series number sets the valve body and connection. The glass length sets the visible range, and the washer material is matched to the service and the gauge model.

Is a liquid level gauge the same as a water gauge, gauge glass or sight glass?

Yes: water gauge, water glass, gauge glass, sight glass, gauge glass set and level gauge all name the same assembly. That is a glass held between two valves so the level in the boiler or tank can be read by eye. Conbraco calls its version a liquid level sight gauge, and the 20-series, 23-series and 24-series are on BoilerSupplies.com.

What do I need off my Conbraco gauge to order the right kit?

Read the series number off the valve body (20, 23 or 24) and measure the glass length, center to center or visible. Then the connection size and type, the working pressure and temperature, and what the gauge is on (steam boiler, water tank, process vessel). For a repair kit, also say which you need: washers, packing, the glass, or the full kit.

Which gauge glass washer goes in my Conbraco gauge, Viton or TFE with Hypalon?

Match the washer to the service and the gauge model. The two materials are listed for different fluids and temperatures. The data for your gauge series says which one is rated for your pressure and temperature. If that data is not at hand, send the gauge series, the service and the operating temperature and BoilerSupplies.com matches the washer.

Why does my Conbraco gauge glass leak at the valve stem?

The valve stem packing has hardened or worn. Tightening the packing nut buys some time, but the fix is new packing. BoilerSupplies.com lists valve stem packing for Conbraco water gauges by gauge series. Order it with the glass washers, because the washers are usually due at the same time and the gauge is already apart.

What is a protection rod on a liquid level gauge for?

Protection rods run alongside the glass and take the knock that would otherwise break it. That matters on a gauge mounted where tools and people pass. BoilerSupplies.com lists them in copper, stainless steel and brass. Pick the material that matches the gauge body and the service, and order the length that matches your glass.
