Johnson Controls R-3710-3007 Restrictor

The Johnson Controls R-3710-3007 is a precision-engineered pneumatic restrictor T-coupling designed specifically for limiting pressure and managing flow direction within complex pneumatic operating systems. Built for the rigors of commercial HVACR applications, this inline barbed fitting is color-coded aqua to signify a fixed .007" orifice, ensuring instant identification during field service. Designed for use with 1/4" OD polytubing, it maintains a maximum operating pressure of 25 psig and delivers a consistent output flow capacity of 45 SCIM (12.3 mL/s) at 20 psig. The durable thermoplastic construction provides chemical resistance and long-term stability in diverse environments. For contractors managing pneumatic logic or terminal unit control, the R-3710-3007 offers a reliable solution for maintaining system balance and preventing rapid pressure fluctuations that can lead to hunting or premature component wear. These restrictor tees are essential for fine-tuning bleed-type controllers and ensuring precise signal transmission throughout the pneumatic circuit.

• Precise Flow Control: The fixed .007" orifice provides a calibrated restriction essential for balancing pneumatic control loops.
• Contractor Friendly Design: Features 1/4" barbed fittings for secure, tool-free connections to standard polyethylene tubing.
• High Visibility: The aqua color-coding allows technicians to verify orifice size at a glance, reducing diagnostic errors.
• Industrial Durability: Rated for a maximum pressure of 25 psig and temperatures up to 180?F (82?C).
• System Compatibility: Ideal for use as a pneumatic restrictor tee in Johnson Controls and other manufacturers' air-operated systems.

Common Questions

What is the purpose of the .007" orifice in a pneumatic system?
The .007" orifice (aqua) is used to create a specific pressure drop or delay in signal transmission, which is critical for the stable operation of bleed-type pneumatic controllers and actuators.

Can the R-3710-3007 be used with copper tubing?
While the barbed fittings are optimized for 1/4" OD polytubing, specialized adapters or the R-3710-1007 series (with compression nuts) are typically required for direct copper tubing integration.

How does this differ from the red R-3710-3005?
The R-3710-3007 has a larger .007" orifice (aqua), providing a higher flow rate of 45 SCIM compared to the .005" orifice (red) which delivers 25 SCIM at 20 psig.
