Application and Buying Notes

If you are replacing air conditioning O-rings, confirm the seal size, profile and refrigerant compatibility before you fit anything. This CA411 assortment is imperial, with 10 sizes ranging from 3/16 in to 3/4 in, so it is intended for jobs where those dimensions match the connection you are working on.

The part number CA411 is the clearest reference for ordering and checking against existing stock. If you are cross-referencing with another listing or a vehicle service record, use the part number together with the imperial size range and R134A/HMBR details to make sure the kit aligns with the job at hand.

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 CA411 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 CA411, 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 o ring 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.

The listed warranty is Manufactures Defect. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

For this listing, part number CA411 remains the key starting point. Correct part selection depends on matching the original unit details, not just the general application description. That is why workshop records, OEM references, and direct comparison with the removed unit remain important wherever there is any doubt.
