Parker 202420 Gasket Kit

The Parker 202420 Gasket Kit is a critical OEM maintenance component designed for the Parker Flo-Con A9 series of pilot-operated pressure regulators. Engineered for industrial refrigeration and high-demand HVAC systems, this kit provides a complete set of high-grade gaskets and O-rings required to reseal the valve body and maintain pilot circuit integrity. This kit is specifically compatible with the A9, A9B, A9E, A9S, and A9SE valve configurations, ensuring a precise fit that prevents refrigerant loss and pressure fluctuations in hot gas bypass or evaporator pressure regulation applications.

As a veteran tech knows, a blown gasket on a pilot-operated regulator can lead to erratic sensing and system inefficiency. The Parker 202420 utilizes durable, refrigeration-grade materials designed to withstand synthetic oils and common refrigerants while maintaining elasticity under varying thermal loads. Whether you are performing a seasonal teardown or responding to an active leak on a Flo-Con A9 regulator, using genuine Parker parts ensures the stack-up heights and seal tolerances meet original factory specifications for reliable modulation and pump-down cycles.

Key Benefits for Technicians

• System Integrity: Specifically matched for Parker A9 series regulators to eliminate bypass leaks and atmospheric discharge.
• High-Grade Elastomers: Materials selected for compatibility with modern refrigerants and lubricants to prevent premature seal degradation.
• Precision Fit: OEM manufacturing ensures that internal pilot ports and flange faces are sealed to exact 15mm to 28mm port requirements.
• Comprehensive Kit: Contains all necessary components for a standard valve overhaul, reducing downtime during field service.

Common Questions

Which valve models does the 202420 kit service?
This kit is engineered for the Parker Flo-Con A9 family, including the standard A9, A9S (electric shut-off), A9E (externally equalized), and A9SE (electric shut-off/externally equalized) models.

Can this kit be used for A8 or A10 series regulators?
No. The Parker 202420 is sized specifically for the A9 regulator series. Using these gaskets on different valve bodies may result in improper sealing and potential system failure.

Is this kit compatible with ammonia systems?
This kit is primarily designed for halocarbon refrigerants used in the Parker Flo-Con line. Always verify your specific valve body material and refrigerant type against the Parker technical data sheet before installation.
