Built from brass, ABS, and reinforced PVC, the set balances accuracy, resilience, and everyday usability so you can diagnose pressures, pull vacuums, and add refrigerant with confidence.\u003c\/p\u003e\n\n\u003ch3\u003eHow accurate and durable are the gauges?\u003c\/h3\u003e\n\u003cp\u003eThe pair of 2.6-inch gauges use a hybrid anti-shock design: an oil-filled core to absorb impact and protect internal parts and a dry dial face for reliable cold-weather readings. Calibration screws let you fine-tune readings to maintain the stated accuracy of around 1.6% over time. The overall housing and fittings are metal and heavy-duty plastic to resist shop wear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2.6\" high and low pressure dials with oil-filled core and dry dial face\u003c\/li\u003e\n  \u003cli\u003eCalibration screws included for periodic adjustment\u003c\/li\u003e\n  \u003cli\u003eSolid brass manifold and fittings for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eABS and rubber body components for impact protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat hoses, couplers, and adapters are included for service tasks?\u003c\/h3\u003e\n\u003cp\u003eThe kit ships with three 5-foot, color-coded PVC hoses—blue for low, red for high, and yellow for service\/charging—each reinforced with four internal layers for routine working pressures.
