Parker OEX Air Conditioning TX Valve Block Pad 2.5 Ton TXX3407

The Parker OEX Air Conditioning TX Valve Block Pad is a block-pad style TX valve for 2.5 ton applications, identified by part number TXX3407. It is listed with an inlet fitting of #6, outlet fitting of #8, and suction fittings of #10, so the connection sizes need to match the vehicle’s air conditioning setup before purchase.

This TX valve is supplied as a single unit, with a stated weight of 0.16 kg and a one year warranty. The super heat setting is 2.8 deg.C / 5 deg.F, which is a useful reference point when comparing the valve against the requirements of the system it is intended to suit.

The product is described as an OEX Air Conditioning TX Valve Block Pad 2.5 Ton and sits in the cooling / AC components group. The fitting note lists inlet 8.50 mm, outlet 11.60 mm, and suction inlet and suction outlet both 14.40 mm, which gives a practical check for anyone confirming the valve against existing pipework or replacement dimensions.

Application and Buying Notes

The key identifiers here are TXX3407, the 2.5 ton rating, and the block-pad TX style. Those details matter because a TX valve is selected to suit the system layout and connection sizes, not just the vehicle badge. If the existing valve is marked differently, or the fittings do not align with #6 inlet, #8 outlet, and #10 suction ports, it should not be assumed to be a direct match.

The stated super heat setting is 2.8 deg.C / 5 deg.F. That is a useful comparison point when replacing a valve in an existing system, but it should be matched to the required application rather than treated as a universal setting. For air conditioning parts like this, the correct part number and physical configuration are the most reliable checks.

This valve is supplied as an each unit and carries a one year warranty. At 0.16 kg, it is a small component, but the impact on the system depends on proper application and installation. A TX valve that is close in appearance but different in tonnage, port size, or style can create avoidable issues, so compare the vehicle details carefully before fitting.

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 TXX3407 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.

OEX Air Conditioning TX Valve Block Pad 2.5 Ton. Part number TXX3407 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number TXX3407, 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.

Compatibility note: Confirm compatibility by matching part number TXX3407, the 2.5 ton block-pad style, and the listed fitting sizes and application details before purchase. If the vehicle has been altered or the air conditioning components have been changed previously, verify the existing valve and line connections rather than relying on the vehicle model alone.
