D-D Type Mud Gauge

Type D-D mud gauges are available in pressure ranges 0 to 1,000psi, 3,000psi or 6,000psi. The large, 7 5/8” diameter-face makes this gauge ideal for mud pumps, choke manifolds and stand-pipe manifolds. They also feature a built-in dampening mechanism to minimize fluctuations and respond quickly to pressure changes. The liquid surrounding the gauge mechanism minimizes the wear from vibrations and reduces mechanical shock. The type D-D mud gauge is available in 2” line-pipe female-threaded connections or can be built into virtually any size flange. DOYLES can also repair your worn or damaged mud gauge.

When determining your mud gauge needs, always overestimate your desired working pressure to prevent over-pressurizing your mud gauge during assembly pressure testing. Please see the following table for suggested selections.
