A/C Service Port Cap – High Pressure Side (Cap H, Parker)

A/C Service Port Cap – High Pressure Side (Cap H, Parker)
Fits 94–06 Civic, Accord, Prelude & More (with Parker hoses only)

Replacement cap for the high-pressure (discharge) service port on factory A/C systems using Parker-brand hoses. Clearly marked with an “H” to denote the high-side port.

Will not fit vehicles equipped with Nichirin hoses—verify your hose branding before ordering.

A frequently missing item on used vehicles or after A/C servicing. Proper port capping is essential to protect system integrity.

Factory Part Number: 80865‑SS0‑A11
Replaces earlier superseded numbers: 80865‑ST7‑A21, 80865‑SV1‑003

Why this cap matters:

• Protects the high-pressure service port from moisture, dirt, and refrigerant loss.

• OEM design ensures perfect fit and seal.

• Compatible primarily with Parker-brand A/C hose assemblies, not Nichirin, so fitment depends on original equipment configuration.

This part appears in OEM parts catalogs for Honda and Acura vehicles equipped with Parker hoses — including various model years of Civic, Accord, Prelude, Odyssey, and more .

Let me know if you’d like to pair it with the corresponding low-pressure version or assemble both “H” and “L” versions as a kit.
