About Pressure Gauges

Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

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.

SMC Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air. These regulators connect to other SMC units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. They have a pressure gauge that's recessed into the body to protect it from accidental bumps. Attach them to a wall or equipment with the included mounting brackets. Install these regulators in your air line after filters.

Relieving Regulators

Relieving regulators exhaust when the downstream pressure exceeds the set pressure.

Joiner Clamps—Joiner clamps (sold separately) create compact, airtight connections between components. These clamps come with mounting brackets.

Tamper-Resistant Padlockable Covers—Padlockable covers (sold separately) clamp over the regulator knob to prevent unauthorized pressure changes.

Compressed Air Filter/Regulators for Particle Removal

A filter and regulator combined into a single unit, these filter/regulators provide clean, compressed air at the pressure you need. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.

Compressed Air Filter/Regulators with Gauge Included—NPT Female Inlet × NPT Female Outlet


Inline with Opaque Bowl and Sight Glass	Stacked with Opaque Bowl and Sight Glass

Inline Components—Inline filter/regulators are connected side-to-side, so each part can be replaced or repaired on its own. They help you reduce maintenance costs.

Stacked Components—Stacked filter/regulators are joined top-to-bottom, so they take up less horizontal space than inline filter/regulators.

Automatic Drain—Bowls with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.

Connect two or more of these regulator manifolds to meet multiple pressure requirements from a single air supply—set a different output pressure with each manifold. Use joiner clamps (sold separately) to connect them to other SMC units of the same series, so you can customize your air preparation system. These manifolds come with one regulated outlet on their back and one unregulated outlet. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Filter/Regulator/Lubricator Joiner Clamps—Joiner clamps (sold separately) create compact, airtight connections between components. These clamps come with mounting brackets.

Filter/Regulator/Lubricator End Block Sets—End block sets (sold separately) allow you to swap out filter/regulator/lubricator components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.

Compressed Air Regulator Manifold End Caps—End caps (sold separately) seal off any unused pipe ports on SMC modular systems. They attach with a joiner clamp (not included).

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

Clean Room Precision Compressed Air Regulators

When precision and cleanliness are critical—such as semiconductor manufacturing and food processing—these regulators are cleaned and bagged in an ISO Class 3 clean room to prevent contamination. They deliver steady air pressure to generate precise, repeatable movement. A locking adjustment knob secures your settings to prevent accidental changes. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Compressed Air Regulators for Double-Acting Cylinders

When your double-acting cylinder sends high-speed air in reverse, a check valve inside these regulators blocks it. They maintain compressed air at the pressure you set, even when the exhaust ports on your control valve can’t keep up with reverse flow. Install them in your air line after filters.

Relieving Regulators—Relieving regulators exhaust when the downstream pressure exceeds the set pressure.

Nonrelieving Regulators—Nonrelieving regulators do not exhaust excess downstream pressure.
