Johnson Controls D-3244-615 Replacement Diaphragm

Upgrade or repair your pneumatic systems with the Johnson Controls D-3244-615 Replacement Diaphragm, a critical OEM component engineered for #5 pneumatic actuators. This Number 5 diaphragm is specifically designed for use in D-3244 and D-3246 piston damper actuators, ensuring precise modulation and reliable force output in commercial HVAC systems. As a veteran-grade pneumatic control replacement part, it handles fluctuating air pressures to maintain the integrity of your building's automation and mechanical sequences.

When performing actuator diaphragm replacement, the D-3244-615 provides the exact fit required to prevent air leaks and ensure the piston rod extends smoothly through its full stroke. Constructed from high-durability reinforced elastomers, this Johnson Controls actuator part is built to withstand the rigorous cycling common in industrial automation and heavy-duty air handling units. Professionals choose this genuine JCI part to maintain pneumatic system efficiency and avoid the alignment issues often associated with generic alternatives.

Key Benefits:

• Broad Compatibility: Engineered for seamless integration with Johnson Controls D-3244 and D-3246 series actuators.
• Optimized Performance: Maintains the required 60 to 70 lb-in head bolt torque specifications for a leak-proof seal.
• Industrial Grade: Designed to handle high-cycling HVAC sequences without material fatigue.
• Technical Precision: Designated as a Size 5 diaphragm to ensure the correct pressure-to-stroke ratio in calibrated controllers.

Common Questions:

Which actuators use the D-3244-615 diaphragm?
This #5 diaphragm is the standard replacement for Johnson Controls D-3240, D-3244, and D-3246 pneumatic piston damper actuators.

What is the recommended installation torque?
For a proper seal on D-3244 models, the head bolts should be torqued to 60 to 70 lb-in (6.7 to 7.9 N?m).

Does this fit multiple actuator sizes?
No, this is specifically a Size 5 component. Using the incorrect size will cause calibration errors and potential seal failure within the pneumatic cylinder.
