Apparatus for coupling a hydraulic line to a pressure gauge, to reduce the level of high pressure transients that are applied to the guage, comprising a housing with an inlet connected to the hydraulic line, a variable volume chamber coupled to the inlet through a small diameter passageway orifice, and a narrow diameter passageway connecting the chamber to the pressure gauge. The orifice which connects the inlet to the chamber is oriented to direct a jet of oil at an angle, such as 30 DEG to 45 DEG with the chamber walls, to create a vortex in the chamber so that the incoming jet pressure wave is well mixed with the fluid contained in the chamber volume, thereby reducing localized pressure pulses or shock waves that could pass through the chamber to the gauge.
