EK-Torque HTC-16 Hard Tube Compression fitting for 16 mm OD hard tubing with G1/4 thread, installed height 15 mm. EAN: 3831109813874 (nickel version). https://www.ekwb.com/shop/ek-torque-htc-16-nickel/03/2020 Update: The model is updated and new files are uploaded. Dimensions come from my own measurements. The model is as accurate as it can be with a cheap, digital caliper. According to EKWB, the installed height is 15 mm, but I measure more at 14.5 mm when the nut is fully screwed in. You probably won't screw the nut all the way down since it's very difficult with the tube in place. However, it's possible if your fingers are strong enough. To reflect this, the installed height is 14.75 mm, but it can be 15 mm as well. The nut is a separate body so you can move it as needed. The thread appears to have an outer diameter of 21 mm with a pitch of 1 mm, so I used M21x1 specification in the model even though it's unusual. Tools are easily available for this type of threading. A chunk of 12/16 mm tube is included as a separate body for convenience and ends 20 mm above the reference plane. Two optional parts are also included: an ABS insert to prevent PETG tubes from collapsing (EK-HD PETG Insert 12/16mm, EAN: 3831109815762) and a color ring visible through compression nuts' openings (EK-Torque HTC-16 Color Rings Pack, EAN: 3831109816417). The peculiar threading of this part is modeled as accurately as possible.
