Glue for kadee couplers

I'm looking for opinions /suggestions on which adhesive ya'll prefer to use for kadee knuckle springs. I have a bottle of cyanoacrylate that is Labeled as a 'gap filling' formula. Not yet sure that I'd want to use that in this situation.

Gap filling glue would fill the gaps in the spring, so I would not use that type.....

To be honest, the only time I've had to place/replace the spring into the coupler is when a spring is missing right out of the package.....I've never had a spring come out during actual use....

But maybe I'm just lucky.....:p

I would say you want thin CA (not the gap filling kind; I keep a bottle of each on hand). Put a small drop on the end of a toothpick and drop it on the end of the spring.

I agree with D&J. I used the gel type CA with
a toothpick to place a tiny dab on one end of the spring.
I never had a problem with it. Did not affect operation
of the knuckles. It's also helpful to do that on the nub
when installing a new spring...let it set before seating the
spring on the upper nub.

Backing a train too hard into a Kadee often causes
the spring to take wing...the glue ended that.
