The Sealey ACOR225 O-ring assortment is a professional-grade kit designed for automotive technicians and DIY enthusiasts performing air conditioning system repairs. Featuring 225 pieces of high-quality HNBR rubber seals, this kit provides a reliable solution for sealing components using R134a and R1234YF gases. While it offers a versatile range of metric sizes, users should ensure the specific internal diameter and thickness match their vehicle's technical manual before installation to avoid leaks.

Yes, the HNBR construction is compatible with R1234YF refrigerant.
While HNBR has good chemical resistance, these are specifically formulated for AC systems and should not be used in high-pressure fuel lines without verifying material compatibility.
Yes, all O-rings in this assortment are measured in metric sizes.
Apply a thin film of refrigerant oil to the ring and the fitting to help it slide into place without binding.
No, this is an O-ring assortment set and does not include picks or installation tools.
Verify that the seating surface is free of debris and that the correct size was selected for the specific groove diameter.
Use a digital caliper to measure the ID and thickness of the original failed O-ring rather than relying on visual estimation.
To ensure maximum effectiveness, always lubricate the O-ring with a small amount of compatible refrigerant oil before installation to prevent pinching or tearing. Verify the dimensions against your vehicle's service documentation, as minor variations in thickness can lead to premature failure. Store the case in a clean, dry environment away from direct sunlight and harsh solvents to prevent the rubber compounds from degrading over time.
