End cap seal failures

Bob, the seal that popped out from aft bulkhead had no indications of sealant on it!

Anyway, I may have a few seals coming from David, and will seal appropriately. Thanks

Was just about to post the link up! Thanks for saving me the trouble!

Email Bob @Drydocks and he may have some. He generally replies the following morning

Thanks! Are these a friction-fit or are the sealed? If sealed, what with?

Is there a commercial source for these? Haven't seen offered at the DryDocks.

Thanks!

The seal bodies within the motor-bulkhead? If so, they are secured with RTV adhesive.

I use RTV Silicone Gasket Adhesive Permatex 81724
The actual seals are only by David or Bob. Bob posted a video on making your own:

As David shows here, easy to replace, I find inserting a 1/16” rod helps inserting into encap

Thanks David and Tom! I'm interested if you're parting with those! And yes, the 1/4" seal bodies to accept 1/16" rod.

In David's green photo above the first item is using a cup seal (great for prop shaft) and the other two are o-rings cast in resin. Those are typically for pushrods, but some also use for prop shafts.
Peace,

What's the best way to install/seal which runs thru end caps to prevent leakage? Two of my seals thru endacp (they appear to be a synthetic rubber material) leak, and the seal from servo to rudder control separated from my endcap completely. Thanks!

Are these the 1/4" diameter resin seal bodies that accept 1/16" pushrods? If so I have a few here you can have.
