→HPCO Sensor Copper Sealing Gasket / Washer (7/16''-20 UNF, OEM) Thermo King Part 33-4277 / 334277
The Copper Sealing Gasket Thermo King 33-4277 (Crush Washer / Authentic OEM Hardware) is a critical consumable component required to ensure a 100% leak-proof seal within the refrigeration circuit when installing high-pressure sensors.
This precision-machined copper washer sits between the X430 compressor discharge manifold and the High Pressure Cut-Out (HPCO) switch (such as part number 42-0708). It is specifically sized for a 7/16''-20 UNF thread standard. When the sensor is torqued down, the soft copper slightly crushes and conforms to the microscopic imperfections of the metal surfaces, creating an impenetrable hermetic barrier. Reusing an old, already-crushed gasket is highly discouraged, as it will inevitably result in slow refrigerant leaks under extreme operational pressures and vibrations.
This sealing hardware is a 100% authentic Original Equipment Manufacturer (OEM) part, listed under the factory catalog reference 33-4277.
Technical Information:
- Hardware Type: Copper Gasket / Sealing Crush Washer
- Component Status: Authentic Original (OEM)
- Thread Compatibility: 7/16''-20 UNF
