Application and Buying Notes

The stated application is for Kenworth C, K & T Series Trucks from 1997 onward. Use the part number RD568681P to confirm you are matching the correct valve, and inspect the physical fittings and mounting style before fitting. Refrigerant system parts need exact matching, so do not rely on model name alone if the vehicle has been modified or the air conditioning system has been rebuilt.

The valve is sold as each and weighs 1.014 kg, which can help when comparing a replacement against an existing unit. If you are replacing a failed TX valve, it is worth checking the old part number, the fitting orientation, and any service history so the replacement matches the original installation as closely as possible.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number RD568681P helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
