978521J000 Hyundai / KIA CAP ASSY-R/DRIER, Price: 8.75$, Weight: 0.012kg

A/C Receiver‑Drier End Cap for Hyundai/Kia ❄️

This small but critical cap seals the desiccant chamber inside the condenser. It keeps refrigerant and oil inside, and moisture and air outside. Without a tight seal, the A/C cannot hold pressure or stay dry, which is vital for cold, clean airflow and long compressor life.

Why you need it

The receiver‑drier filters debris and traps moisture. The end cap locks the desiccant pack in place and seals O‑rings. This protects the expansion valve, evaporator, and compressor from corrosion, icing, and wear.

How it works

A machined plug with O‑rings is secured in the condenser side tank. It compresses the desiccant bag and maintains a leak‑free path for refrigerant. Proper sealing holds system pressure and ensures stable subcooling.

If it fails ⚠️

Expect weak cooling, hissing, oily stains near the condenser, moisture ingress, acid formation, “black death” sludge, high head pressure, and possible compressor damage. The fix is replacement, new O‑rings, vacuum, and correct refrigerant/oil charge.

Tech tip

Always replace O‑rings, lubricate with PAG oil, torque to spec, evacuate to deep vacuum, and leak‑test before charging.
