Application and Buying Notes

Before ordering, compare the part number TXX8778, the 90 degree left-hand layout, and the externally equalised TX style with the valve already fitted to the vehicle. The listed connection sizes are important: inlet #6 3/8 MF, outlet #8 3/8 MF, and external capillary fitting 1/4 FF. If any of these differ from the existing unit, the valve may not be the correct replacement even if the vehicle name appears in fitment references.

The 2 ton rating and 4.4 deg.C super heat setting are important identifiers for the valve’s intended application. In practice, TX valves are matched to the system setup, so the vehicle model alone is not enough. Confirm the current air conditioning arrangement, the original valve orientation, and the available space for the 305mm capillary and 419mm external capillary before purchase.

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 TXX8778 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.

For part number TXX8778, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. 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.

Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

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 compatibility by checking part number TXX8778, the 90 degree left-hand externally equalised configuration, and the listed fitting sizes and capillary lengths against the existing vehicle installation before ordering.
