The Honeywell 310143 Packing Cone is a critical 1/4-inch black rubber component engineered specifically for stem sealing in pneumatic valve assemblies

Key Benefits: Precision Metering: The #46 drill size ensures the exact natural gas delivery required for compatible Weil McLain boiler models

Ensuring a secure electrical termination is critical for the long-term reliability of any submersible system

Precision Alignment: Facilitates proper stem packing compression to prevent localized leaks and reduce mechanical stress on the actuator

Corrosion-Resistant Construction: Built to withstand the fluctuating humidity and airflow conditions common in industrial HVAC ducting

Hartland Controls CAP-20/5/440 Run Capacitor The Honeywell 310143 Packing ConeThe Hartland Controls CAP 20 5 440 is a high performance 20 5 MFD 440V dual run capacitor engineered for critical HVACR motor and compressor applications. Designed to replace the legacy 12880 part number, this 370 440 VAC multipurpose component delivers consistent torque and power factor correction for both the compressor and the condenser fan motor. Built to UL 810 standards and EIA 456 compliance, it features a rugged aluminum oil filled oval case
