O-Ring With Oil Kit

The O-Ring With Oil Kit from Vintage Air is an essential maintenance and repair component designed for air conditioning systems that use AN (Army-Navy) standard fittings. This kit serves technicians and vehicle owners who need to maintain refrigerant system integrity during installation, repair, or seasonal servicing. O-rings are critical sealing components that prevent refrigerant leaks and contamination in AC systems, making this kit indispensable for anyone working with Vintage Air AC fittings or similar automotive cooling applications.

This kit includes o-rings sized for 10 AN, 8 AN, and 6 AN connections, covering the most common refrigerant line diameters found in classic and modern vehicle AC systems. The rubber o-rings are engineered to withstand refrigerant exposure and maintain a reliable seal under pressure, while the included refrigerant oil lubricates fittings during assembly and ensures proper seating. The premium construction prevents premature degradation from thermal cycling and refrigerant compatibility issues, delivering the durability needed for both professional service shops and DIY enthusiasts pursuing proper AC system maintenance.

Technicians working with Vintage Air AC systems, custom automotive cooling setups, and universal refrigerant line applications benefit most from having this assortment on hand. Whether replacing worn seals, assembling new AC lines, or troubleshooting refrigerant leaks, the multi-size approach eliminates multiple part purchases and reduces downtime. Installation is straightforward: apply a light coat of the included oil to each o-ring before inserting into AN fittings to ensure proper lubrication and seal integrity. Compatible with standard AN fitting ports across 6 AN, 8 AN, and 10 AN sizes commonly found in automotive air conditioning systems.
