• 1/4" FPT Gauge Adaptor W/1/8" Probe

The Bard 8603-027 gauge adaptor is an OEM service accessory used on Bard geothermal and water-source systems to connect a pressure gauge to a 1/4 inch FPT port while providing a heavy-duty 1/8 inch probe for pressure and temperature testing at P/T ports and flow center fittings. This adaptor is commonly used with Bard ground loop and ground water accessory kits during startup, flushing, and troubleshooting to verify loop pressure conditions and help confirm proper flow center operation. As a genuine Bard part, 8603-027 is built for correct fit with compatible Bard service fittings and helps technicians take accurate readings without improvising field-made connections.
