Return-Path: <jschroeder@perigee.net> OK - Here is a copy of my email to Rob. I hope the attachments make it. John ======================= Rob - I am attaching the Colder catalog because it has many other choices than the ones we used. They also have manifolds for 1/8" npt in and out. I like the idea that Bob Pastusek has of a manifold attached to the panel with tubes going to each instrument as needed. I would still put a quick disconnect on each box/instrument so that it could be removed without taking out the whole panel or having to cut or wrench off a line. Pages 16 & 17 are the series we used and the same series BMA uses on their EFIS CPU. We uses two Colder PMC2201's for taking the pitot and static lines from 1/4" OD to the 1/16" ID of the Proprietary Software AOA lines. They connect to two PMC1703's that are pushed into the Nyla Seal 1/4" OD tubing. We used two PMC2402's that thread into the Dynon EFIS. They also connect to the pitot and static system via two PMC1703's The TruTrak autopilot is on the bottom of the stack and it was too difficult to "T" and route the pitot line down to it. We also installed a separate static port to feed the AP because there were so many other devices feeding off of the main static line. There is a Note about this in the TT install manual. We cut into the pitot line just after it gets behind the panel and installed a different type of "T". We got these items from McMaster-Carr. They are used for gas and fluid lines and are push-ons. You can also push the collar in (?) or out (?) to remove them. The area for the autopilot is very congested so I used a 45 degree and a 90 degree that have 1/8" NPT on one end. They screw into the tray of the TT AP. That made it one hell of a lot easier to work with the stiff Nyla Seal in a congested area. When we decided that we should have drains at the low points of the lines, we also used this line of fittings to "T" off and the cap the drain line. When we build the next airplane :-)), I will use all of these type of fittings (McMaster & Colder) and probably a more flexible tube. The McMaster fittings are harder to disconnect than the Colders, but one hell of a lot easier than having to put 2 wrenches on the standard fittings in tight places. 90 degree swivel EL: 5779K151 (page 138 of catalog) 45 degree swivel : 5779K333 (page 138 of catalog) I also ordered a couple of fittings from page 139. The (DOT) rating seems to be the only difference. They are interchangeable. Search for the part numbers on http://www.mcmaster.com/ to get to the catalog pages. See attached pictures. I goofed and didn't take any of the Colder fittings as installed. Hope this helps. Let me know if you need more info.
