ACTECMAX Universal A/C Compressor SD508 5H14 2-Groove Clutch R134A 12V with PAG-100 Oil

If your vehicle's air conditioning compressor has failed, this ACTECMAX universal compressor assembly supplies the compressor body, magnetic clutch (hub, pulley, coil), and factory-charged PAG oil so you can replace the unit in one service. It fits systems using R134A refrigerant and 12V electrical supply, and is built to connect with common five-rib drive setups and threaded refrigerant ports used on many cars and light trucks.

Will this compressor fit my vehicle's air conditioning system?

The ACTECMAX unit is designed as a universal-style replacement compatible with many systems that use SD 508 / 5H14 compressors and R134A refrigerant. Confirm fit by checking port threads, clutch groove count, and electrical specs.

• Clutch grooves: unit supplied with a 2-groove pulley; contact seller if your vehicle requires a different groove count.
• Suction port thread: 7/8 inch-14 UNF; discharge port thread: 3/4 inch-16 UNF.
• Voltage: 12V electrical coil compatible with standard automotive systems.
• Drive compatibility: suited for 5-rib (5H14) belt configurations.

How is the compressor prepared for installation and what oil does it contain?

The compressor arrives pre-filled with 180 ml of PAG-100 oil to protect internal components during shipment and initial start-up. If your vehicle’s system already contains a different PAG oil, follow best-practice service steps to match oils or flush the system before connecting the new compressor.

• Factory-filled with 180 ml of PAG-100 lubricating oil.
• If existing system oil differs, drain or flush to avoid cross-contamination and preserve compressor life.
• Includes the magnetic clutch assembly—hub, pulley, and coil—installed for plug-and-play replacement.
• Follow standard A/C service procedures for evacuation, vacuum, and recharge after installation.

What hardware and parts are included, and are there return conditions?

This ACTECMAX package includes the compressor body and the magnetic clutch components to give you a complete replacement assembly. Returns are accepted only if the unit and label remain intact, so handle packaging carefully if you plan to return it.

• Included: compressor body plus magnetic clutch (hub, pulley, coil) ready for mounting.
• Ports: suction and discharge threads as specified for easy hose connection.
• Return policy: keep original packaging and label intact for any return request.
• If the delivered clutch differs from the described 2-groove type, contact the seller for corrective options.

How do I ensure durable performance after installation?

Long-lasting operation depends on matching oils, proper evacuation, and secure electrical and belt installation. Inspect seals, replace drier/accumulator if needed, and ensure the belt alignment and tension match factory specifications.

• Flush or match PAG oil to avoid lubrication incompatibility and wear.
• Replace receiver-drier or accumulator when replacing the compressor to protect system cleanliness.
• Evacuate and vacuum the system before recharging with the correct refrigerant and oil levels.
• Verify clutch engagement voltage and belt alignment after mechanical assembly.

Who is this for: This ACTECMAX universal compressor assembly is intended for DIY mechanics, independent repair shops, and fleet service technicians needing a complete 12V replacement compressor for R134A systems using SD 508 / 5H14 configurations. It’s best suited for those who can verify port threads, belt type, and clutch groove requirements and who will perform or supervise proper system flushing and refrigerant service to ensure reliable operation.
