The adapter fit properly on my Tasso core, was dense and has the core prima drawn with a cheap pump 12 (B0001P1972) in vacuum. The 2x2.2m Mono core I could carry into the car comfortably under his arm.
To connect I used the Premium Connectors Gardena (B0013HOAGY) and a solid Gardena hose (B00HPXVIPQ). Has everything together cost only 56, which was worth the independence :-)
