I need to know what is available for spring loaded plungers, clips, etc. and am also open to new ideas..

I'm trying to lock to assemblies together and have been considering a spring plunger.

Basically i have a water filter housing that needs to connect to a manifold assy. both are threaded together, but high water pressure unscrews the two apart..

We currently use a clip, but was thinking a spring loaded plunger press fitted into one assy would help lock the components together and would allow for easy install/removal.

I know you all are the smartest bunches of peeps i know......and go! 

thanks in advance,

Jared M.
