Silicone Oil Filled: Liquid-filled damping reduces vibration, mechanical shock, and pressure pulsations for more stable pressure readings. Effectively eliminates liquid leakage caused by corrosion, moisture penetration, and freezing.
Features an air vent. If the pressure gauge needle fails to reset, remove the air plug to release internal gas, allowing the needle to automatically return to zero.
Easy Installation: 1/8-inch thread size fits most piping systems. Includes PTFE tape for convenient, leak-resistant installation.
Dual-Scale Display: 1.5-inch dial features PSI and bar scales with 2.5% accuracy, suitable for diverse pressure testing scenarios.
Meets professional pressure testing needs for piping systems, heating equipment, HVAC systems, automotive applications, irrigation pumps, engines, and more.Silicone oil offers superior insulation properties compared to glycerin, ensuring gauge stability even under high-pressure and high-temperature conditions.
