Honeywell 309292 Diaphragm

The Honeywell 309292 Diaphragm is a critical replacement component engineered for high-performance pneumatic systems. This 5-inch neoprene diaphragm is specifically designed for use with the Honeywell MP516 series pneumatic damper actuators, and it also serves as an OEM-spec replacement for the MP953 series and legacy part number 310673. Constructed from industrial-grade neoprene, this component offers superior flexibility and chemical resistance to withstand the rigors of constant cycling and harsh mechanical environments. For technicians maintaining HVAC pneumatic controls, this diaphragm ensures an airtight seal, preventing pressure loss and ensuring the precise modulation of dampers and valves. Unlike standard rubber alternatives, the neoprene material used in the MP516A diaphragm remains resilient under fluctuating temperatures, maintaining the integrity of the pneumatic actuator and extending the service life of the entire assembly. For optimal field service, always verify the actuator diameter and series compatibility before installation to ensure a drop-in fit and peak system efficiency.

• Precise Actuation: Ensures consistent pressure response for accurate control of MP516 damper actuators.
• Durable Neoprene Construction: Designed to resist fatigue and environmental degradation in demanding mechanical rooms.
• Cross-Series Compatibility: Direct fit for MP516, MP953, and 310673 models, simplifying inventory for service trucks.
• Leak Prevention: High-tensile material maintains an airtight seal to prevent pneumatic control system failure.

Is the Honeywell 309292 compatible with the MP953 series?
Yes, this 5-inch diaphragm is a compatible replacement for both the Honeywell MP516 and MP953 series pneumatic actuators.

How do I know when to replace the actuator diaphragm?
If you notice a slow response in damper modulation or audible air leaks near the actuator housing, the neoprene diaphragm may be perforated or hardened and requires immediate replacement.

What is the advantage of neoprene over standard rubber for this part?
Neoprene offers superior resistance to oils, chemicals, and temperature extremes compared to standard natural rubber, making it the industry standard for HVAC pneumatic repairs.
