waterproof? Rubber seal, or O-ring?

O ring. There is a pressure relief valve for flying so i wouldnt call it waterproof but close to it.

Not sure. Very tight case. It has a pressure relief screw valve. Good case. Worked on airlines. Sold the rifle and case so I cannot look now.

The official word from the manufacture is "water tight". I wouldn't drop it in the lake just for fun, but holds up to nasty weather just fine.

Mine shipped with O-rings installed and a spare set. Yes, you need them in place before diving. When you twist off the head they go under the head around the open end. If you don't see the grooves they are probably already in place.

Yes, this item is indeed waterproof as long as you make sure it has a tight seal. Thank you

It is water proof. If the o rings go bad they can easily be purchased at your hardware store to be replaced. Has sponge in cap for holding calib. Fluid to keep it accurate and corrosion free. Finally you pay for what you get. There is a reason those are cheaper and this one is a lot more expensive and not just a little. Think about it like two glass jar one thicker more expensive and the other thinner less expensive. They will both do the same exact thing but one is a lot easier to break or something happen to it. So you buy the thinker one so less likely of a chance of something happening and needing it especially when it's a needing moment.

Surefire calls their lights weatherproof with o-ring and gasket seals. However, I have used this light and other models from Surefire underwater for short durations with no issues or water intrusion. Hope this helps.

o-rings and plastics will last longer if you avoid using petroleum lubricants, I would use silicon grease.

This is an interesting question. The device consists of a main unit, with a cap. To attach the cap, you need to press fairly hard, and it has an o-ring. It is unlikely that the cap creates a waterproof seal, but once the cap has been placed, it would be possible to seal it with some melted wax, or something like that, to preclude water coming in. I would suggest putting the device into a zip-lock bag, a high-quality one. That would protect the device from water, without interfering with its ability to record temperatures.

It has o rings but I would think it's probably more water resistant than waterproof.

While I have not tested this myself, the can does have a rubber o-ring, and a clasp that seals the whole thing shut. The handle is secured to the top of the can by two alcoves that are on the exterior of the box. All in all, it is a good buy and should be considered watertight.

in the end i used the 3/4 inch diameter (internal) version for better water flowi used a 1 3/8 inch masonry bit and sealed around the edge with epoxyit was a nice tight fit and has not leakedi was careful only to use the epoxy on the inner section so as not to prevent screwing on the seal ringi feel that the 3/4 inch version should be better for a 1 1/2 inch diameter holegood luck - i hope the hole is not too long as the tubing is not. i am certain the 1/2 inch version will be too small based on my experience

Any hardware store will have rubber grommet type o-rings that should help I have never had a problem with mine but I think that would be the easiest cheapest solution! Hope that helps.

There is no rubber or plastic seal. It's metal on metal with a very tight fit. Mine doesn't leak.

I bought the solid ring oar locks to use on mine. They work best for choppy water by keeping the oars in the locks. The "U" shape locks will pop the oars out, especially since they are buoyant.

No rubber gasket around the base. As far as the internal construction goes, it is best just to ask Sigma directly. When it rains, I go indoors with my camera, so not too concerned with weather sealing.

Will likely need a threshold seal as well to be completely waterproof. This will be 95% effective on its own.

The probe appears to be sealed in rubber. To be sure it waterproof I would encapsulate it in silicone.

Do you mean the o-ring? its ok but put some antifreeze (coolant) on it to make it slippery enough to install the pump without damaging the rubber
