A detailed 3D animation of a boat's propeller shaft and stuffing box featuring a heavy duty dripless style stuffing box from R.E. Thomas Marine Hardware.
If you're curious how a boat's shaft sealing system works, you'll appreciate this video. If you're looking to upgrade or replace a "face seal" dripless system or "lip seal" dripless shaft seal, you'll also want to watch this video.
R.E. Thomas self-aligning shaft seals feature the same benefits as a modern dripless shaft seal, while giving boaters the peace of mind and proven reliability of a more traditional bronze stuffing box.
There's no carbon face seal to shatter or crack. There's no rubber bellow to lose elasticity or compression. There's no nylon hose barb to snap off. There's no stainless rotor to slide back on the shaft.
R.E. Thomas self-aligning shaft seals are much easier to repair in an emergency, and mariners have trusted the underlying technology for over a century.
Manufactured in the U.S.A., R.E. Thomas SA-Series stuffing boxes offer an uncompromising combination of safety and performance that professional mariners have come to expect and trust.

For those that think, 'wow, neat, gotta get one!'...heads-up, I just saw a 47-year old traditional shaft-seal / stuffing box (flax seal) that was STILL in operable shape on a sailboat with a 1-1/4" shaft...and had NEVER been serviced other than a new seal a couple of times! Yes, stuffing boxes 'drip water'...but are cheaply and easily fixed. A catastrophic bellows failure on a 'dripless seal' will sink your boat in an hour-or-two! Conventional stuffing boxes CANNOT 'catastrophically' fail...so a decent bilge pump in working conditions prevent OBVIOUS boat-loss. I wouldn't even CONSIDER this on a vessel less-than 60-ft and 450-hp, PERIOD! You've got a houseboat running twin 200-hp engines...stick with 'old school' and a redundant set of bilge pumps! If you do '20-year service' on those prop shafts, and polish them out (complete with buffing pads and jeweler's rouge), you'll have a VERY NICE (and relatively water-free) seal you don't really have to worry about.

I don't have a boat... do I still need one of these?

@scottwise1980

This just looks like a traditional stuffing box that they added a hose barb to so you think it is something new.

@UQRXD

Change the packing yearly- forget it.

@Raul28153

what prevents leaking when the boat is sitting at the pier?

Is this an improvement over the "Last Drop" system that came out about 20 years ago? Those seemed to work very well and gave long service and appears similar to your product.
