Denso Air Conditioning TX Valve Block Pad TXX3180

The Denso Air Conditioning TX Valve Block Pad, part number TXX3180, is a block-style TX valve supplied as a single piece. It is listed with a #6 inlet fitting, #8 outlet fitting, and #10 suction inlet and suction outlet fittings, so the connection sizes should be checked carefully before ordering.

Fitment information is provided for Subaru applications, including Legacy, Liberty and Outback references across multiple model years. Because air conditioning valves must match both the vehicle application and the physical connection sizes, the part number TXX3180 and the fitting details are the key checkpoints to confirm before purchase.

Application and Buying Notes

When comparing this valve to the vehicle, the first checks are the part number TXX3180 and the connection sizes. The listed fittings are #6 inlet, #8 outlet, and #10 suction inlet and suction outlet, with measured passages of 10.0 mm, 15.5 mm, and 18.3 mm respectively. Those dimensions need to suit the existing air conditioning plumbing.

The fitment references point to Subaru Legacy, Subaru Liberty and Subaru Outback applications, but the exact vehicle match still needs to be confirmed against the compressor, pipe layout and any original valve markings. Air conditioning TX valves can look similar across models while still differing in connection size or internal calibration.

This unit is supplied as a block-style TX valve, so it is important to confirm that the vehicle uses a block or pad style mounting arrangement rather than a different valve format. The listed tonnage is 0, so the practical buying decision should rely on the application reference, the TXX3180 part number and the fitting measurements rather than any assumption about capacity.

The valve weighs 0.14 kg and is sold as each, which is useful if you are comparing pricing or replacing a single failed component. The one year warranty applies to the part as supplied, but the installation outcome still depends on correct application matching and sound system condition.

If the existing valve has a readable number, compare it directly with TXX3180 before ordering. If the vehicle has been modified, or if the air conditioning pipes have been changed, the safest approach is to verify the physical fitting sizes and the valve style rather than relying on the model name alone.

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 TXX3180 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.

Compatibility note: Confirm compatibility by matching the part number TXX3180, the block/pad valve style, and the listed fitting sizes before ordering. Vehicle references should be checked against the exact application and the existing air conditioning plumbing.
