About Pressure Gauges

Pressure Gauges

These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.

Miniature Pressure Gauges

The small dial on these gauges allows for installation in tight spaces.

Pipe Size Measuring Kits

Kits contain pipe fittings in a variety of sizes so you can determine the size of a pipe or fitting without measuring.

Dimensional Measuring and Size Checking

Threaded Plug Gauges with
Handle for Pipe Threads

Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly.

Threaded Ring Gauges for Pipe
Threads with Calibration Certificate

These gauges come with a certificate that’s traceable to NIST, confirming they were calibrated in a lab. Use them to verify whether external pipe threads are within tolerance.

Threaded Ring Gauges for Pipe Threads

Confirm that external pipe threads are sized within tolerance.

Thread Identifier Sets

Set includes calipers and gauges to identify external and internal threads

Pipe Thread and Thread Pitch Identifiers

In addition to checking NPT and BSPT pipe sizes, use the two included gauges for measuring thread pitch.

Grease Fitting Size Identifiers

Take the guesswork out of determining a grease fitting’s thread type and size.

Compressed Air Regulators

SMC Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Parker Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air.

Compressed Air Regulators
for Double-Acting Cylinders

An internal check valve permits reverse flow, so these regulators work with double-acting cylinders.
