Relesable instrument tubing
Any hints how to fabricate releasable instrument tubing, to enable
removing the entire instrumnet panel from the glider for winter storage.Winter sells "5 way quick tube connector", I would need something similar solution, but maybe a better and reliable, because I feel this is not 100% safe avoiding leak. |

I have used Winter quick couplers in my last two sailplanes. They have "O" rings that prevent leakage. If "O" ring seals work on your Prandl tube, why wouldn't they be good enough for a coupler?

I once had trouble with a small leak between lines on the Winter. I don't
know of a better substitute. The addition of lubricant to the "o" rings would probably provide reliable sealing. Bob wrote in message oups.com...

I have done 3 ships with removealble panels. An ASW 20, a Ventus Bt
and a Nimbus 3t. All using the Winter quick coupler. Never had any trouble. I used the older Winter 4-way coupler many, many years ago and did have occasional leaks. The problem then was that the seal for each of the four connections was formed by two O-rings pushed face to face. If the coupler was not firmly pushed together to compress these O-rings, leaks were quite possible, including across two connections. AFAIK, the seals used in a multi-probe are formed by tubes sliding into O- rings. So long as the tube is pushed through the O-ring, a good seal is guaranteed unless the O-ring is damaged or worn. If Winter has changed their coupler design, my comments are irrelevant. If the design is the same, I wouldn't necessarily avoid using their quick coupler but I would be careful connecting it: pushing it together a bit and then spinning the knurled knob may not insure a perfect seal 100% of the time. You should push, tighten, then push again and tighten until it's certain that it's truly tight. And, from experience, I'd be tempted to run a leak test the first few times just to make sure. But that sort of defeats the purpose of a quick connector device, I suppose. Chip Bearden ASW 24 "JB" |

The "O" ring will not leak air if kept in good condition (smooth,
clean). I use high quality medical type quick connect/release tubing couplings, one for each line. You can use the same for a pee-bag disconnect. http://www.smallparts.com/products/d...tions/2170.cfm http://www.sciencelab.com/page/S/PVA...2/60-197230202 I also like to use colored tubing from Wings and Wheels. - John |

I suggest using silicone rubber lines on the panel side, connecting to a barbed fitting on each line on the glider. The silicone lines remove easily, even years later, and form a good seal. If you think you might get the lines mixed up when reinstalling them, then the Winter connector would likely be a better choice. -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * "Transponders in Sailplanes" http://tinyurl.com/y739x4 * "A Guide to Self-launching Sailplane Operation" at www.motorglider.org |
