Application and Buying Notes

Before ordering, compare the part number TXX3433 with the valve currently fitted to the vehicle. This is especially important because the listed fitment covers multiple heavy vehicle makes and model families, and the connection sizes must line up with the existing system: inlet #6, outlet #8, suction inlet #8, and suction outlet #10.

If you are cross-checking by application, note that the fitment information points to Freightliner, Kenworth, Mack, Nissan, Sterling Trucks and Volvo references, with many applications starting from 1999 onward. Because multiple chassis families are listed, the safest approach is to confirm the vehicle model, year and air conditioning layout against the part number and fitting sizes rather than relying on make alone.

This valve is sold individually and weighs 0.2 kg, which can help when checking freight estimates or comparing to the removed component. The product is a Parker air conditioning TX valve under the cooling and AC components groups, so it is intended for system matching rather than general-purpose substitution.

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 TXX3433 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number TXX3433, the block-threaded TX style, and the listed fitting sizes before ordering. Vehicle make, model, year and existing air conditioning line arrangement should all be checked against the application details.
