Motorcraft A/C Accumulator Service Cap Mustang 2010-2014

Do not overlook the small parts: a missing or damaged A/C accumulator cap can compromise your entire air conditioning system’s integrity. This Motorcraft A/C accumulator service valve cap is designed to seal the accumulator’s low pressure service port on 2010-2014 Mustangs, protecting the system from dirt, moisture, and contaminants (YF2122). Made to OEM standards, this cap screws onto the service port to provide a secondary seal beyond the internal valve, guarding against environmental contamination and helping maintain proper refrigerant integrity.

Features and Benefits:
- Factory quality service cap
- Ensures proper fit and seal on the accumulator’s low pressure valve
- Seals out dirt, dust, debris, and moisture 
- Prevents valve core contamination and corrosion, protecting sensitive A/C internals
- Screw-on cap replaces missing or damaged originals, no special tools required
