Prevent Refrigerant Leaks - with high-strength rubber and metal sealing
A rubber sealing element paired with metal components creates a tight interface at the service port, reducing pathways for refrigerant to escape. The combination of elastomer and metal maintains seal integrity under thermal and pressure cycles.
Fewer leaks mean the air-conditioning system retains charge longer and requires fewer top-ups. Owners see more reliable cooling performance between services.
OEM-compatible Fitment - thanks to listed OE numbers
Supplied references include OEM numbers 3C0 820 231, 3C0 820 795, 8E0 820 855 and KTT500012 to match original equipment specifications. Matching OE numbers helps ensure correct dimensions and thread fit at the service port.
Correct fitment reduces the risk of cross-threading or poor seating during replacement. Suitable when matching the vehicle's original part numbers for a like-for-like repair.
Quicker Maintenance at Home - with simple design and DIY-friendly installation
