FJC R134a Retrofit Adapter

The FJC R134a Retrofit Adapter line gives you retrofit service port adapters (also called R134a conversion fittings or A/C service port adapters) for converting an older R12 air conditioning system to modern R134a refrigerant. Each adapter threads onto the existing service valve. It lets you connect standard R134a manifold gauges and charging equipment.

Key Features:

• Converts the original R12 service ports to accept R134a quick-connect couplers
• Separate adapters for the low-side and high-side service ports
• Angled design helps with hose clearance and access in tight engine compartments
• Helps prevent accidental cross-connection of refrigerants and service equipment
• Made by FJC, a long-established supplier of A/C components, tools and refrigerant accessories

These adapters are a practical part of an R12-to-R134a retrofit. They help you get a clean, standard connection for evacuating, charging and diagnosing the system. Choose the variant that matches the port you are converting.
