I looked at a 2 piece design a number of months ago but did not think it could be made rigid enough to be reliable so stopped work on it there.
|
Well that?s no fun! :(

Anodizing
What color are they and are they all pre-sold? I?d be interested in a set for a 6 cylinder.
|
We'll have gold and red here and I only have 4 red ones spoken for on this batch so far.
I can let you know when we have the clamps come in as we are completely sold out of those at this time. |
I installed these on my IO-540 last annual.
Very easy install, they seal really well. Worst part for me was getting all the old paper gasket off. Very happy with mine, thanks Ross! Any more cool upgrades coming along to help me part with my money? |
Great, thanks!

Already have the valve covers - installed, and dog approved!

Look good on there. Thanks for posting the photos. :)

Ross,
PM sent for set of 4 SDS Aero O-ring Sealed Induction Tube Flanges. Carbureted O-360, Parallel Valve, Gold Anodized, 1.75". Lhanks, Larry |
Clamps Soon!
Ok, my supplier has the clamps in Canada now so I should have them by Monday or Tuesday and can start filling outstanding orders soon after. Thanks to everyone for their patience.
|
I finally have lots of the CT clamps in hand now so am starting to ship more of these kits again. Sorry for the long wait.
|
I am needing to replace my gaskets and hoses (with CT clamps vs the screw type I have on today). I am a little confused as to whether this will work with my setup and prefer not to have to cut and weld.
I have a Superior IO360, parallel valve, cold air induction, fuel injected model. The intake tube has a slight taper/bulge where the hose connects the intake tube to the cold air sump. I don?t know the diameter of the tube where the slight bulge is located. Does anyone have a similar setup and have tried it or know if these will work without modification? Thanks! |
I installed my intake seals today. I tried every method. I liked the tape idea but I noticed that the spring clamps on my combo just barely tightened down to the intake tube. So I slid them up, and used them to hold the flange in place instead of tape.
Slide a spring clamp up to push the flange to the stop. Keep the space between the two tabs on the clamp away from the bolts. Put on the O-ring and aluminum ring. Push it up in position, insert bolts and tighten until 1/8" inch away. Take a flashlight to make sure the rings are still seated. Tighten, slide the clamp down, and torque. Put the spring clamps in position. Done. Pics available if desired. |
So excited..
I have had issues the same as most folks have described in various threads regarding having to swap out the paper intake seals every 200 - 300 hours. I had an induction leak get mean on a night flight and thankfully I had an awesome airport 10 miles ( I was at 9500) away and landed. After I figured out what happened I was just so darn frustrated with this part of the engine going bad again. I carry those paper seals with me in the plane and have had to preplace them on the road. Sigh... I ran across what Ross and Toobuilder came up with. I am hopeful and excited. I ordered the kit today and have faith in their idea. So excited and hopeful that this is the last time I have to mess around with this particular part.
Thanks Ross!! |
Got a whole herd of gold and red flanges back from the anodizer yesterday if folks want to fix this problem once and for all during annual.

Pliers
Found a great tool for the constant tension clamps.
At Home Depot online..... It is a large tool and can handle the intake tube clamps without stress. Much easier than the channel locks etc. Also works on the smaller drain back hose clamps as well. The end sockets that grab the ears for the clamps rotate to help get in there to align the clamp where you want it. https://www.homedepot.com/p/GearWren...-205594175-_-N |
Would Like to Order a Complete Kit for 0320
Hello, I would like to order a complete set for my 0-320. I have 1 3/4 inch diameter induction tubes. Red would be good or whatever color is available. Please PM me with the details on completing the order.
Thanks Pat |

You?ll have to go to Ross?s website to order the parts or give him a call. http://www.sdsefi.com/aircraft.html http://sdsefi.com/cpi2.htm |
I sent a PM to Pat early this morning.

Superior sump idea
I have the superior sump as shown in the photo.
@Ross - would you guys be able to pre-buy some of the tubes, and then offer a kit which is already welded? Then we could send you back our tubes to be re-welded for the next guy. Like returning an empty coke bottle. ![]() I'm sure that there is a market for that - charge a lot. :D |
Unfortunately my ace welder friend retired last year so I don't have an economical alternative who can do top quality work.
Ideally, if Superior would be agreeable, they could install our flanges during the manufacturing process if they'd agree to respect my IP. |
We just received another run of flanges from the machine shop and anodizer on Friday so have a decent stock of clear, gold and red flanges in stock again for those interested. As always, thanks for your patience.
Our machining partner who makes these is working 7 days a week to try to keep up with demand for his services from SDS and other clients. He'll be adding a new Haas VF-4 in the coming months and expanding his shop space to the adjacent bay to accommodate it. This should reduce lead times on many of our parts- but I've said that before... :o |
Aloha
I'm a bit confused with the welding discussion. I have been led to believe that it is really hard to weld anodized aluminum without having to remove the anodizing layer and thus making a mess. Are these flanges welded on? |
Quote:

The welding only comes into play if the flange blocks cant slide on/off the tube as typically seen on the angle valve engines and some aftermarket examples. In these cases, the tube needs to be cut to remove the old flange blocks and install the SDS parts, then the tube is welded back together.
|
I installed mine today on a Lycoming O-360 A2A.
Very impressed with the idea, and part quality. It was a very straightforward and easy installation. I used Knipex Cobra 250mm Spring Hose Clamp Pliers 85 51 250 A. These are superb. Can’t wait to run the engine. Cheers Wayne Blackler IO-360 Long EZ VH-WEZ AUSTRALIA |
Glad you like them Wayne. Proper spring clamp pliers certainly make compressing the clamps easier than using channel locks.
Thanks for supporting SDS. :) |
Ross
Could you provide a version that is split with flanges and bolts that would be assembled onto the angle valve intake tubes? With the precision machining available it should not be a problem. The loads on the joint would be minimal. |
Bruce,
I evaluated several split designs last year and couldn't come up with anything that was comfortably rigid to do the job properly IMO. Also at this point in time, we lack enough local machining capacity to add any more new products to our line. The shop that produces the current flanges is always seriously backlogged in keeping up with orders from us and his other clients. This should change with the addition of a new VF-4 mill towards the end of this month. Priority has to be given to the EFI kit parts as that is our main focus. We've been trying to get the new Rotax 912 kit parts done for over 2 months... Almost there now. |
Induction pipe mod
Hey Ross,
We had several email exchanges about possibly getting Superior to put your flanges on first, understand they haven't been responsive. I was reticent about cutting and welding the Superior pipes, but so glad I did! What an absolutely great mod. No intake leaks, easy to remove, etc. I had a high-school kid cut and weld the pipes with TIG, no big deal. It would be great if Superior got onboard, but not such a big deal to cut/weld the pipes. Would highly recommend this mod to anyone, it's such an improvement over the paper gaskets. Just my two cents. Ed |

Tig welder
Just do it. I took 4 new tubes from Superior and had them cut install the flanges and Tig them up for $60 bucks. Worth it!
|
New Vid Up
I had some requests to make a video on installing the SDS flanges, so here it is: https://youtu.be/8JfnA9FygfQ
|
Ross - do you have the hoses and clamps now for the Superior forward facing cold-air sumps?

Trevor is down to one mill for part last week and this week. 2 of 3 mills and the lathe had to have mold scrubbed out this week and coolant changed. That's what happens when you are too busy to perform maintenance because you work 7 days a week for 3 years trying to keep up... It comes back to bite you with a vengeance.:( Should have all 4 machines back running by Thursday. I hope. |
