Grainger 4FLZ7B Pressure Gauge, 0–100 PSI, 1/8-Inch NPT

Compact 0–100 PSI pressure gauge with a rear connection

This offer includes one new-in-box Grainger 4FLZ7B pressure gauge, with a white dial marked in both psi and kPa. Its rear threaded connection keeps the fitting behind the face, so check your equipment's connection and clearance before choosing this replacement.

What makes it useful

• Read pressure on a 0–100 psi scale with a secondary 0–700 kPa scale.
• Compact round design with a black ABS case.
• Bronze tube and brass socket, as marked on the gauge face.

Before installation

Match the model, pressure range, thread and rear clearance to your equipment. Confirm that the equipment's working fluid is compatible with brass and bronze. Have a qualified person install it according to the equipment manufacturer's instructions, with the system depressurized. Do not use for oxygen service. Do not assume suitability for safety-critical applications.

Questions before buying

Is this a tire-pressure gauge?
No. This is a threaded equipment pressure gauge, not a handheld tire gauge with a valve chuck.
