Hi Zhenyu, Flemming, and Rahul,

The actual design for the connector is attached (slightly different than the one in Rahul's slides). 

We designed the "head" of the connector with 6.75 mm in diameter which is larger than the 6.35 mm hose, so it will be a tight fit. 

Cheers,

Yi

Hi Yi

I think the drawing "say for tube ø6"   not 6.5. The 1/4" current tube
is 6.35
