21940713 Adapter | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Y-shaped reducing adapter for 10 mm connections, from the Cooling System group, listed for three HPCU and TB applications. The Y shape and 10 mm size are the defining details, since the adapter splits or combines a flow path and must match the connected hose bore.

🚤 Compatibility

Typically suits:

• Volvo Penta HPCU-A
• Volvo Penta TB66-A
• Volvo Penta TB66-150-A

• Engine Family: HPCU, TB

⚙️ Key Features

• Y-shaped reducing adapter
• 10 mm connection
• 0.012 kg
• Listed for three applications across HPCU and TB installations
• Must match the bore of the hose it connects

🔌 Function

Splits one flow path into two, or joins two into one, and steps the connection down to 10 mm at the reduced end.

⚠️ Common Signs of Failure

• Weeping or dripping at one of the three connections
• Adapter cracked at the branch
• Hose ends split where they have been forced onto the wrong size spigot
• Clips loose or corroded
• Flow restricted by debris caught at the branch

🛠️ Service Notes

• Match the hose bore to the 10 mm connection - a hose stretched onto the wrong spigot will not seal and splits at the end
• Support the adapter so the branch is not carrying the weight of the hoses
