  • ColorGreen
  • Measures up to 160 psi for versatile pressure testing

  • 1/4 inch MNPT bottom connection fits standard plumbing fittings
  • Dual scale reads 0 to 1100 kPa alongside psi
  • Accuracy within +/-2-1-2 percent ensures reliable readings

Purpose and fit

The Zoro Select 4EFH4 is a bottom-mounted pressure gauge built for plumbing and automotive test work where a 0 to 160 psi range and 1/4 in MNPT connection are required. Its green ABS plastic case and brass/bronze wetted parts suit general-purpose fluid systems.

Sustained-load behaviour

The gauge is rated at +/-2-1-2 percent accuracy across the full 0 to 160 psi primary scale with a 1 psi smallest graduation, and a secondary 0 to 1100 kPa scale is provided. It is not liquid-filled, so needle response remains direct without damping during extended pressure cycles.

Interface limits

The 1/4 in MNPT bottom connection fits standard pipe threads but the gauge is not panel-mountable, restricting installation to in-line or stub-up positions. No calibration certificate is included, so critical applications may require separate verification. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

Does the Zoro Select 4EFH4 generate any noise or heat during continuous pressure monitoring?

The gauge is a mechanical ABS plastic and brass instrument with no moving electrical parts, so it produces no noise or heat while reading up to 160 psi.

What pipe fitting must already be in place for the 1/4 in MNPT connection to seal?

A female 1/4 in NPT port on the pipe or manifold is required; the gauge’s male taper threads directly into that opening.

Will the +/-2-1-2 percent accuracy hold when the gauge is mounted on older brass or steel pipework?

Yes, the stated +/-2-1-2 percent full-scale accuracy applies regardless of the pipe material, provided the 1/4 in MNPT threads engage correctly.
