Denso Air Conditioning Compressor Shaft Seal CPX355 – Front Lip Type

This Denso air conditioning compressor seal is a shaft seal, supplied as a front seal to suit Denso 10P15, 10P17 and 10P20 compressors. It is listed under part number CPX355 and is sold as an each item, which makes it suitable for replacing a single worn seal during compressor servicing.

The seal is described as a lip type, and the unit make is Denso. At 0.12kg, it is a small consumable component rather than a complete compressor assembly, so it is important to confirm you are ordering the seal only and not expecting a full compressor or other climate control parts.

This product sits in the AC consumables group and cooling category. It carries a one year warranty, which gives a clear reference point for after-purchase support, provided the part is used in the correct application and installed properly.

Application and Buying Notes

The key compatibility checkpoint here is the compressor model. This seal is specified for Denso 10P15, 10P17 and 10P20 compressors, so the compressor casing and shaft seal arrangement need to match before purchase. Part number CPX355 should be checked against your existing seal or workshop listing to reduce the risk of ordering the wrong consumable.

Because this is a shaft seal rather than a complete compressor, it is designed as a service item. The lip type design and front seal application are the main identifying details provided, so buyers should verify that the compressor being repaired uses the same front seal style and Denso unit make before fitting.

The unit is sold individually and weighs 0.12kg, which is useful when confirming you are ordering one seal only rather than a kit or a larger assembly. If you are matching replacement parts for a repair job, compare the compressor model, the CPX355 part number, and the Denso branding together, not just one detail on its own.

The one year warranty applies to the supplied part, but correct selection and installation still matter. For compressor seal work, take care to confirm the exact compressor type, because even within the same general family the seal profile and application can differ. If you are uncertain, a parts interpreter or compressor specialist should verify the application before the vehicle is returned to service.

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 CPX355 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 CPX355, 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 compressor seal 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Please confirm fitment by checking part number CPX355, the Denso unit make, and the compressor model against your existing component before ordering.
