Need some advice on creating a waterproof container that allows for a sliding stainless steel rod (sh.itjust.works)

Hello lemgineers!

I'm working on designing a claw that can be operated underwater. The plan is to use a linear actuator in a waterproof housing. The main issue is allowing the shaft to slide through without causing a leak. What's the best way to go about this?

Would depend on how deep underwater and the pressure and so forth, but maybe look at how steam engine piston rods are sealed - an o-ring or a wiper seal would probably do the job
