Boshart HARPG No-Lead Pressure Gauge, 0-100 PSI

The Boshart HARPG Series is a no-lead pressure gauge built for rough-in and mechanical room installations where a plumber or contractor needs a quick, reliable read on system pressure. This series is rated for a 0-100 PSI range and connects via a 1/8" fitting, making it a compact option for tight installation locations behind manifolds, pump stations, and water distribution equipment. The HARPG Series is available in two mount configurations — Back-Mount and Bottom-Mount — so plumbers and contractors can select the orientation that best fits their piping layout and available clearance. Both configurations share the same 0-100 PSI reading range and 1/8" connection size, differing only in how the gauge attaches to the assembly. The HARPG Series is manufactured to no-lead specifications, supporting its use in potable water and general plumbing pressure-monitoring applications where lead-free components are required. As a rough-in accessory, this gauge is intended to be installed by a licensed plumber or contractor as part of a larger piping assembly, not as a standalone consumer fixture.

Key Features

  • Pressure Range: Reads from 0-100 PSI, suitable for typical residential and light commercial water supply pressure monitoring.
  • Connection Size: 1/8" connection sized for compact installation into manifolds, pump assemblies, and distribution piping.
  • Mount Configuration Options: Available in Back-Mount or Bottom-Mount styles, letting installers choose the orientation that fits the piping assembly and available clearance.
  • Flush-Face Dial: Designed so the dial face sits flush for easy reading in tight mechanical spaces regardless of mount style chosen.
  • No-Lead Construction: Manufactured to no-lead standards for use in potable water plumbing systems.
  • HARPG Series: Boshart's designated series for this pressure range and connection configuration, spanning both mount options.

Boshart HARPG2002-4L – Frequently Asked Questions

1) Which mount style of the Boshart HARPG pressure gauge should I order, back or bottom?
Pick by how the gauge sits in your piping. The Boshart HARPG comes in two mount configurations: back-mount (MPN HARPG1002-8B), where the stem exits the rear of the case so the dial faces straight out from a manifold or panel, and bottom-mount (MPN HARPG2002-4L), where the stem comes off the bottom for a tee or riser below the gauge. Both read 0-100 PSI and both use the same 1/8 inch connection, so the only decision is orientation and clearance.
2) What size port do I need to install a Boshart HARPG gauge?
A 1/8 inch gauge port. The HARPG connects through a 1/8 inch fitting, which is the small tapping you'll find on well tanks, pump control assemblies, and manifold bodies. If your tee or manifold has a 1/4 inch gauge tapping, you'll need a 1/4 x 1/8 bushing to adapt down.
3) Is a 0-100 PSI gauge the right range for a house water supply or well system?
For typical residential and light commercial water supply, yes. The HARPG reads 0-100 PSI, which brackets normal municipal street pressure and standard well pump cut-in/cut-out settings (commonly 30/50 or 40/60 PSI), leaving usable dial above the cut-out point. For boiler or high-pressure hydronic work above 100 PSI you need a higher-range gauge instead.
4) Will the HARPG gauge fit in a tight mechanical space behind a manifold?
That is what it is built for. The HARPG has a compact 1/8 inch connection and a flush dial face so it can be read in cramped spots behind manifolds, pump stations, and distribution equipment. The gauge weighs 0.190 pounds, so it is light enough to hang off a small tapping without additional support.
5) Do the back-mount and bottom-mount HARPG gauges read the same pressure range?
Yes, identical. Both share the 0-100 PSI range and the 1/8 inch connection size; they differ only in how the gauge attaches to the assembly. If you are standardizing gauges across a building, you can stock both orientations without changing the reading range your techs are used to.
6) Can a homeowner install the Boshart HARPG gauge themselves?
It is sold as a rough-in accessory, meant to be installed by a licensed plumber or contractor as part of a larger piping assembly rather than as a standalone fixture. It threads into an existing 1/8 inch gauge port on a manifold, pump assembly, or tank tee.
