Graco Air Regulator 104266 – 0–250 PSI Pressure Control

The Graco air pressure regulator 104266 helps technicians control compressed air in lubrication systems. Its adjustable design supports consistent pressure settings for compatible equipment. Additionally, the zinc-plated construction suits demanding workshop environments.

The regulator accepts air through a 1/2-inch female inlet and delivers air through a 1/2-inch female outlet. Its tee handle allows straightforward pressure adjustment during routine operation. Furthermore, multiple outlets support connections for equipment, gauges, or ball valves.

With a maximum regulated pressure of 250 psi, this regulator supports a range of air-powered lubrication applications. The maximum air inlet pressure is 300 psi. Meanwhile, the maximum airflow rate reaches 90 SCFM under suitable operating conditions.

The regulator also includes a 1/4-inch NPT gauge port for pressure monitoring. Technicians can use this connection to install a compatible pressure gauge. However, the gauge is not included with the regulator.

This Graco air pressure regulator is designed for use with Monark and President Lube Ranger equipment. Its adjustable range starts at 0 psi, giving operators flexibility when setting the required pressure. The listed operating temperature range is 40°F to 120°F.

The package contains the regulator only. Therefore, confirm the required fittings, gauge, and installation accessories before ordering. Check your existing connections and equipment requirements to ensure compatibility.
