Sealtight fittings not holding

I have older sealtight fittings that are not holding newly installed sealtight. Any ideas on how to make this work without having to disassemble everything to replace the fittings?
 
most seal tight I have seen does this over time. I don't think there is a real fix short of replacing it.

you could try gluing it with gorilla glue. probably not entirely kosher but likely effective. gorilla glue expands and seeps out so you will need to come back later and cut off the excess.
 
Another thought : What type of seal tight fitting ? One looks similar to a compression

connector or the ole barb that just slides down the inside diameter of the conduit ?

I have never had any of the connectors I have installed come loose.

You are lucky. I have seen a lot of flex of various kinds come loose over the years. The connectors don't come out but the seal tight falls away from the connectors.

You can install grips on them that helps.

I think it is the weight/force being applied to the flex along with the vibration.

And stumble bum tech's steping on them. Usually it's a case of not being installed right in the first place. They get hand tightened only.

I have seen a lot of loose ones over the years. Very few appeared to have been stepped on. Perhaps an installation issue.

IME it is less likely with the all plastic version than with the stuff that has the metal under the plastic outer layer.

There is no reason a properly installed sealtight fitting will fall apart.

By properly installed I mean the fitting is instaled correctly, tightened and the sealtight is supported as required.

You must see a lot of poor practices.

So hand tightening the connector will hold the sealtight in better than if you snug it up with a tool? That doesn't seem right.

I think he meant that hand tightening was why they come apart.

I am mostly in the industrial field and most of the flex applications I see that open up are on machines with a lot of vibration. I have always suspected that the vibration coupled with a little bit of side ways force on the connectors is what causes them to pop open over time.

It is one of the reasons I prefer cord on machines. Can't recall ever seeing a cord grip fail.

Most that I've seen come apart weren't strapped properly.
 
Be sure your connectors are compatible with your flex. Some are not. A few metal connectors are made that are good with nonmetallic flex but not metallic. The pieces will not fit at all. With metal flex, I always found that the steel connectors were far better than the die cast type. With nonmetallic, I like the Arlington brand connectors where you simply slide the flex in, with no insert to screw in. I use nearly all nonmetallic now. I used to dislike it but it is very durable, more flexible & much cheaper.
