Light-duty general purpose pressure gauges have threaded back or bottom mounting connections for lighter-duty commercial and contractor applications with minimal vibration or pulsation. Light-duty panel-mount pressure gauges have a flange or U-clamp that mounts them into a control room or contractor's panel. Light-duty vibration-resistant pressure gauges are designed to reduce the movement of the dial pointer and minimize the effects of vibration or pulsation in general contractor or jobsite applications.
