Graco 15B566 Hose Cap

In‑Depth Details on the Graco 15B566 Hose Cap

Compatible Use & Applications

The Graco 15B566 Hose Cap is designed for use with Graco fluid‑handling and spraying systems to securely seal off hose ends during idle periods or maintenance.

• Seals unused hose ends
• Prevents contamination inside the hose
• Stops fluid or solvent leakage when disconnected
• Can be used during equipment storage or transport

Product Description

This OEM hose cap is a simple yet essential component that protects the internal passage of Graco spray hoses. Made from durable polymer or rubber-like material, it provides a tight seal when the hose is not connected to fluid or gun assemblies.

Its design helps prevent fluid evaporation, dust ingress, and corrosion when the hose is disconnected, thereby extending the life of the hose and safeguarding your system’s integrity.

Key Features & Specifications

Why This Cap Matters

Without a proper hose cap, disconnected spray lines are vulnerable to contamination and drying out. By using the 15B566, you preserve internal hose cleanliness and prevent damage to seals or internal passages — an inexpensive part that protects your system’s more vital components.

Maintenance & Replacement Advice

• Inspect the cap for cracks or hardening periodically.
• Replace it if the seal no longer holds or material degrades.
• Store capped hoses upright or coiled neatly to reduce stress on the cap.
• Clean the cap and hose opening during maintenance to avoid debris buildup.
