Parker Air Conditioning TX Valve 90 Deg (L) Externally Equalised 2 Ton TXX8078

The Parker Air Conditioning TX Valve 90 Deg. (L) is an externally equalised valve rated at 2 ton, with part number TXX8078. It is supplied as each and suits applications where a 90 degree left-hand TX valve arrangement is required, with #6 MIOR inlet fitting and #8 MIOR outlet fitting.

Key published measurements include an external capillary length of 248mm and a capillary length of 305mm. The super heat setting is 4.4 deg.C, which is a useful checkpoint when matching the valve to the system design rather than relying on a visual match alone.

This is a Parker cooling component used in air conditioning systems, and the listed style is externally equalised. Weight is 0.16kg, and the product is covered by a one year warranty. As with any TX valve, the correct fitting sizes, orientation and system requirement should be confirmed before purchase.

Application and Buying Notes

For a TX valve, the most important checks are part number, valve orientation, fitting size and system requirement. In this case the key identifiers are Parker TXX8078, 90 Deg. (L), externally equalised, with #6 MIOR inlet and #8 MIOR outlet fittings. If the existing valve uses different connection sizes, different capillary length, or a different equalisation style, it should not be treated as a direct match.

Capillary length also matters. This valve lists an external capillary length of 248mm and a capillary length of 305mm, which can affect installation and routing in the vehicle or machine. Take care to confirm available space and the layout of the existing air conditioning components before fitting.

If the existing system uses another brand or a different valve arrangement, compare the physical fittings and the part number before placing the order. The supplied fitment references cover several Caterpillar, Holden and Jaguar applications, but the safest approach is to match the component details already installed on the vehicle or equipment.

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 TXX8078 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.

Parker Air Conditioning TX Valve 90 Deg. (L) Externally Equalised 2 Ton. Part number TXX8078 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TXX8078, 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.

Available application references include CATERPILLAR 120G, CATERPILLAR 120G 1995, CATERPILLAR 120G 1996, CATERPILLAR 120G 1997, HOLDEN BERLINA, HOLDEN BERLINA 1984. 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 using part number TXX8078, the 90 Deg. (L) externally equalised configuration, and the #6 MIOR inlet / #8 MIOR outlet fittings before ordering. If the existing TX valve differs in orientation, tonnage, capillary length or fitting size, re-check the application carefully.
