SeacureX Type Mouthpiece (Black 4, 4)

I chewed through my reg’s original mouthpiece on the first dive and barely made it to the fifth dive before it separated completely. So glad I got this! Very easy to shape and mold. Also extremely comfortable. I did have to use a separate zip tie as it was too large around to use the original piece from the Apeks XL4. Would be nice if it came with a fitted no bump tie. Going to get another one to add to my personal Save-a-dive bag!

Have used these for years. Got this one for new second stage. Eliminates jaw fatigue. Love them. Easy to set up and mount.

Zero jaw discomfort after 4 dives of use. Highly recommended.

Just got back from a 2 week trip in Fiji. I love how you don't need to bite down on this to keep it in place. I didnt bite my last one but it was smaller so it would move around a little more. I didn't have a problem before but this is an improvement. It is harder than the original rubber mouthpiece most regulators come with but I had no issues with it. My wife says hers is the best upgrade she has done. No more sore jaw muscles

Amazing fit and quality. I have braces and recently had jaw surgery. This is by far the best mouth piece I’ve ever tried.
