Bottom Male-Thread Pressure Gauge — NPT / BSP Options

Male connection below the case

A male threaded stem projects from the bottom of the round gauge case. This radial arrangement places the dial above the instrument port for local pressure observation. The visible external thread distinguishes this gauge from the clamp and union versions and is the first interface to compare when replacing an instrument.

NPT and BSP thread selection

The listed connection families are NPT and BSP. Select the required thread family and size to match the instrument port; similar appearance does not establish interchangeability. The mating port and sealing method belong in the connection specification, together with the space needed to fit and remove the gauge.

Material and gauge-version options

AISI304 and AISI316L are listed stainless steel choices, while the gauge types are described as with oil and without oil. The measuring range is selected to order. Specify these choices with the dial unit and required calibration so the purchase description identifies the complete intended instrument.

Reading and maintenance access

Keep the dial visible and leave clearance around the lower connection for appropriate installation tools. Plan instrument removal without interference from neighbouring fittings. Routine maintenance includes checking the visible thread-joint condition, keeping the dial readable and arranging calibration or replacement under the site instrument procedure.
