FJC R134a Service Port Cap

The FJC R134a Service Port Cap is a replacement A/C service port cap (also called an A/C valve cap or refrigerant service valve cap) for automotive air conditioning systems that use R134a refrigerant. It threads onto the low-side or high-side service fitting and covers the port when the system is not being serviced.

Key Features:

• Seals the A/C service port to help keep dirt, moisture and debris out of the fitting
• Helps protect the Schrader valve core and the port threads from contamination and damage
• Works as a backup seal to help keep refrigerant in the system
• Replaces missing, cracked or worn caps
• Made for R134a A/C service fittings
• Offered in several configurations for low-side and high-side service ports

A cap that is in good condition helps keep your A/C system reliable and makes later service easier. Choose the variant that matches your system's service port.
