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?

Thanks for all your responses! I should have mentioned that pneumatics and hydraulics are off the table at this time.

Right now we're thinking of manufacturing a flexible seal that can travel with the rod while maintaining a seal with the housing. That might be over engineering a bit, but we'll be doing some testing this week to see how it goes!
