Description
The AD84L Automotive Cylinder Adapter – 1/2″ ACME F x 1/4″ SAE M is specifically designed for use with R1234YF / HFO1234YF refrigerant cylinders, providing a secure and reliable connection for automotive A/C service applications. Featuring a 1/2″ ACME left-hand female fitting to a 1/4″ SAE flare male connection, this adapter allows technicians to safely connect compatible refrigerant cylinders to standard service hoses and equipment.
Manufactured from durable brass, the AD84L cylinder adapter ensures strength, corrosion resistance, and dependable sealing performance. It is suitable for use with Dupont R1234YF cylinders; however, it is not compatible with Honeywell cylinders that use a 22mm thread. The left-hand threaded design provides proper alignment and safe handling when working with R1234YF systems, making this cylinder adapter an essential accessory for professional automotive refrigerant servicing.
