21656860 Star Connection | Genuine Volvo Penta Part

🔧 Product Description

Y-connector for the Volvo Penta cabin air heater in the 60 mm size, weighing 0.1 kg. It sits between the 55 mm Y-connector 21656859 and the 80 mm 41103316 in the range. The published weight is identical to that of the 55 mm connector, so weight will not tell the two apart - order by the stated duct diameter.

• 0.1 kg
• 55 mm is 21656859 and 80 mm is 41103316
• This and the 55 mm connector share the same published weight, so order by duct diameter

🔌 Function

Splits one 60 mm warm-air duct into two branches so a single run can serve two cabin outlets.

⚠️ Common Signs of Failure

• Cracked or split connector body
• Hose working loose at one of the three spigots
• Air leakage at the branch, with weak flow at both outlets
• Restricted flow where the body has been crushed out of round
• Rattle or duct detachment with the fan at full speed

🛠️ Service Notes

• Heater 21621755 is the 60 mm outlet version, so it is the one whose warm-air side is built around this size
