Maintenance, Regulators & Plumbing

In a compressed air system (which is what this collection covers), a regulator is a valve that reduces and stabilizes the air pressure coming from your compressor tank down to a safe, consistent level for a specific tool or application — like our California Air Tools Pressure Pot Regulator, which steadies line pressure at 60 PSI for spray equipment.

In a compressed air setup, regulators generally fall into single-stage models (a single diaphragm that controls output pressure directly, like most compressor-mounted gauges and regulators) and precision regulators, which offer finer control for sensitive applications like spray painting or pressure pot work.

A compressed air regulator can last many years with proper use, but should be inspected periodically for diaphragm wear or leaks — components like our California Air Tools regulators are built for continuous shop use and typically outlast the compressor's other seals and gaskets under normal conditions.

For a home's water supply, a licensed plumber installs a water pressure regulator; for a compressed air system like the ones in this collection, a shop owner or technician typically installs air regulators and fittings directly onto the compressor's output line — no plumbing license required, just basic pneumatic fitting know-how.

Compressed air regulators and fittings like the ones in this collection are inexpensive and simple to install yourself, generally costing between $15 and $100 depending on the component, without needing to hire a professional plumber.

Installing a compressed air regulator or fitting, like our California Air Tools components, typically takes just a few minutes with basic hand tools — thread sealant, a wrench, and screwing the fitting into your line is usually all it takes.
