Unique-Bargains Wire Cap Connector 20mm Inner Diameter 6 Vanes

Wire Cap Connector with Six Vanes

This off-white plastic connector features a 20mm inner diameter and six vanes designed to increase cooling system efficiency. It serves as a direct replacement for a stock plastic fan vane, helping to prevent damage to both the fan and the engine. The unit weighs 30g and has an overall height of 22mm. It is supplied as a single fan vane wheel.

Fits 20mm Motor Shafts

The component mounts onto a motor shaft with a 20mm inner diameter, requiring no additional adapters for that specific size. Its maximum outer diameter reaches 140mm, so the surrounding housing must accommodate this width. By replacing a worn or damaged stock vane, it restores proper airflow without modifying the existing motor assembly. The 22mm height ensures it seats within the original fan shroud depth.

Six-Vane Airflow Capacity

The six-vane configuration moves enough air for standard cooling duties on compatible small engines or motor assemblies. It runs out of headroom when the application demands higher static pressure or flow rates than the fixed blade geometry and 140mm diameter can provide. The plastic construction handles normal operating temperatures but is not suited for extreme heat environments beyond standard specifications.
