Transfer elbow for 4 × 6 mm tube: a 90° turn in a syringe engine's transfer line
How do I turn a 4 mm ID silicone transfer line through 90° between two syringe tips? · Hardware · basis: Tube sizes from the silicone-tube entry (4 ID × 6 OD); sockets drawn at the tube OD, flow bore at the tube ID

Notes
- Two Ø10 arms at 90° meet in a rounded corner. Each arm ends in a port face 13 mm from the corner with a Ø6 socket 8 deep: the 6 mm OD tube pushes in until its end bottoms 5 mm from the corner. A Ø4 flow bore (the tube's ID) joins the two socket floors through the corner.
- Used where a transfer line has to turn: two on the can engine (up from the cap barb, across, up into the Luer tip), two on the Ross yoke alpha (tips up, 40 mm apart: up, across, down), three on the alpha V-twin (tips pointing away from each other at ±45°).
- The sockets take the tube's OD exactly (see Mating features).

Questions
How far does the tube go into the transfer elbow?
8 mm, to the socket floor; the tube end then sits 5 mm from the corner and the Ø4 bore carries on round it.
