Stuck strobe connector and bulkhead caps

Hi Everyone,

Ran into a small problem getting the caps off of my housing (caps that cover the strobe sync cables when the cables are not attached). The same caps that cover the connectors on my strobes are also stuck. I got one off but it took a ton of forceful turning. I can't get the others off. On the one I got off, it looks like there is a little corrosion on the treads so maybe a little moisture was on these threads. Does anyone have any suggestions how I can get the caps off without damaging the connectors?

Thanks!

Is it threaded? Gently tapping for several minutes will usually loosen a threaded connection that becomes stuck.

Try some warm vinegar and dip them into it.

Yes, they are threaded. Thank you. Will give it a try.

Thank you. I'll give it a go.

This won't help you get them off, but once you do you could try a little petroleum jelly on the threads (not o ring) before doing them up. This stops salt water corrosion and therefore sticking.

Great idea! Thank you. I will start doing this.

You may tra also Corrision-X, WD-40 or CRC on the stuck cap, but change the o-ring after you get it off.

I personally would be careful with petroleum jelly, as it may reach somehow th o-ring and alter him.

I use a thin film of the silicone greease supplied by the manufacturer on the treads.

Another way to retard corrision is to seperate the metals by teflon pipe dope

The best thing to avoid corrision and especially galvanic corrision is to seperate the metals by unscrewing them.

If you unscrew the caps after every dive they wont stuck anymore.

Removed mine after some difficulty. That will teach me to loosen the threads next time when storing!

Got mine loose after some tapping and useing a bit more force than "normally". Now I open and clean them after every 20 dives or so. No problems anymore.

I use crystal lube on the threads of my sync cords. This prevents the locking nut from freezing stuck and also allows the sync cord to screw in and out with ease in the housing. It leaves a coating behind, thus allowing the bulkhead cap nuts to turn easy.

I figure if it is used in regulators as an inert lube, it will not hurt the sync cords.
