Watts R75-03C Air Reg

The Watts R75-03C is a professional-grade 3/8" NPT air regulator engineered for precision pressure management in demanding pneumatic and industrial air handling systems. Part of the QUBE modular FRL system, this unit features a diaphragm-operated design with a balanced poppet, ensuring rapid response and highly accurate regulation even during significant flow fluctuations. Built with a durable zinc body and high-quality Buna-N seals, it handles a 300 PSI maximum inlet pressure and provides a reduced output range of 0-125 PSI at a rated flow of 45 SCFM. As a direct replacement for 1360012, R55-03C, and 21-483, it offers a compact footprint with integral mounting slots and dual 1/8" NPT gauge ports. This industrial pneumatic regulator is an essential component for contractors looking to maintain consistent secondary pressure, protect downstream equipment, and optimize air preparation setups in HVACR and manufacturing environments.

• Direct Cross-Reference: Drop-in replacement for the R55-03C, 1360012, and 21-483 models, simplifying maintenance and service calls.
• Precision Performance: The balanced poppet design minimizes the effects of supply pressure variations on the regulated output.
• Versatile Installation: Compact modular design with panel mount capabilities and a non-rising adjustment knob for tight mechanical spaces.
• High Flow Efficiency: Delivers reliable 45 SCFM delivery at 100 PSIG inlet, suitable for most medium-duty pneumatic control applications.
• Industrial Durability: Rugged metal construction and Buna-N diaphragm rated for temperatures from 0°F to 125°F.

• How do I install this into an existing QUBE FRL stack? The R75-03C connects to other QUBE modular units using standard machine screws and O-rings, eliminating the need for bulky mounting brackets.
• Can I use this regulator with a pressure gauge? Yes, the unit is equipped with two 1/8" NPT gauge ports located on the front and back for flexible orientation.
• Is this model a relieving or non-relieving regulator? The standard R75-03C is a relieving type regulator, allowing downstream pressure to exhaust when reduced at the control knob.
