Parker OEX Air Conditioning TX Valve Block Threaded 1.5 Ton TXX3439

It is listed with an inlet fitting of #6, outlet fitting of #8, suction inlet fitting of #8, and suction outlet fitting of #10, so the connection sizes need to be checked carefully against the existing system before ordering.

The unit is described as a block - threaded TX style and weighs .22kg. For buyers replacing a failed valve, the critical checks are the part number TXX3439, the threaded block style, the 1.5 ton rating, and the listed FIOR fitting sizes.

Application and Buying Notes

When replacing a TX valve, the most important match points are the part number TXX3439, the block threaded TX style, and the fitting sizes listed as inlet #6, outlet #8, suction inlet #8, and suction outlet #10. If any of those do not line up with the existing part, the valve should not be treated as a direct match.

Because this valve is supplied as a threaded block style, the physical layout matters as much as the part number. Compare the orientation, thread type, and the FIOR fitting notes before fitting, especially on older vehicles or when the air conditioning system has been modified.

This is an air conditioning component rather than a universal part. The fitment data supplied does include several vehicle groups, but the safest approach is to confirm the original valve, the vehicle application, and the connection sizes side by side before ordering.

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 TXX3439 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning tx valve in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
