High-Pressure Differential Gauges

These gauges are able to withstand line pressures up to 3,000 pounds per square inch. They are commonly used to measure pressure differences in pumps and filters.

Manifold-Mount Compressed Air Regulators

Multiple Regulators

Shown Installed

(Manifold Sold

Separately)

Mount these miniature regulators on a manifold (sold separately) to create a regulating manifold. Each regulator can be set to a different output pressure, so you can power multiple tools or machines with a single air supply. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

NPT Male Inlet × UNF Threaded Female Outlet

Panel-Mount Nut—Regulators with a panel-mount nut can be installed through a hole in a panel or enclosure. They let you hide your air lines without losing access to the control knob.

Easy-Set Compressed Air Regulators

A pressure-calibrated dial on these regulators allows for easy adjustments to outlet pressure in high-flow applications. They are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Precision Compressed Air Regulators

Use these regulators in sensitive applications that require constant, consistent pressure for precise force and movement. They’re often used on calibration stands in laboratories or with air-powered clamps that hold delicate items. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Relieving Regulators

±0.1%

Regulating

Accuracy

BSPP Inlet Thread—BSPP threads are also known as G threads.

±0.1% Regulating Accuracy—Regulators with a ±0.1% accuracy have a sensor and a servo-adjustment mechanism that work together to monitor pressure and instantly adapt to input pressure changes—even when conditions change. They have a locking nut to prevent accidental pressure changes.

Mounting Brackets—Mounting brackets (sold separately) let you attach the regulator to a wall or equipment.
