No jaw fatigue!

By Woody

Product arrived faster than I thought and was well protected.


Great experience. Happy customer

By Rich B.

Very happy! All products came in a timely manner and as expected! Great prices also

SeaCure is a unique, moldable mouthpiece designed to precisely fit the individual diver's mouth, teeth, gums and jaw configuration to provide maximum support of a regulator and, thus, eliminate jaw fatigue. The professional as well as the recreational diver will find SeaCure to be extremely well suited for all types of diving conditions. The newest model, the X Type, offers a totally new X shaped profile, which significantly reduces bulk, virtually eliminates gagging and improves molding by earlier engagement of the teeth during closure. The new X Type also includes an improved one piece molding and sealing attachment with a bite limiter which eliminates the possibility of over closure during the heat molding process. Over closure reduces air flow during diving. The attachment is used in the molding process and then to keep debris out of the regulator. Mouthpiece comes with a convenient holder with chain. Oh Yea! Don't forget the tie wraps to attach it with! See: SKU AQUTW10 Tie Wrap. The following is a size compatibility for the mouthpiece:
Size 1; Fits standard orifice regulators 1-1/8" x 1/2" (2.86 x 1.3 cm)
Size 2; Fits intermediate size orifice regulators 1-3/16" x 5/8" (4.75 cm x 1.59 cm)
Size 3; Fits same diameter as a size 1 with double retention ribbing
Size 4; Fits orifice regulators 1-5/16" x 11/16? (3.33 cm x 1.75 cm)
Size 5; Fits orifice regulators 1-7/16" x 13/16? (3.66 cm x 2 cm)

No jaw fatigue!

Product arrived faster than I thought and was well protected.


Most Liked Negative Review


Not for me...

The thought was intriguing, a custom fit to my mouth / teeth. The reality is that when you turn your head it pulls and stresses areas I wasn't accustomed to. I realized that I hold me regulator mouthpiece loosely when I dive, letting it move slightly when I look around. The restriction of such fixed mouthpiece was very uncomfortable to me. My wife felt the same way. These were removed after 4 dives or so and our old mouthpieces reattached immediately.

No jaw fatigue!

By Woody

Product arrived faster than I thought and was well protected.


Great Product

By K9 R.

This is my second SeaCure mouthpiece, and I like it even more than the first, which I used for over eight (8) years! The mouthpiece is softer and lighter than my old one. I really appreciate the custom fit and longer side bite tabs, which keep the regulator in proper position with requiring constant use of jaw muscles.


Great Equipment!

By K9 R.

This is my second Seacure mouthpiece (the 1st lasting -10-yrs!)and I could not be more satisfied! It is more comfortable than the older style, ad provides a great custom fit! I experience no jaw fatigue due to the custom fit and longer bit tabs! I strongly recommend use for all divers!


Every diver should have this.

By Steve

Great product, every diver should use this. Huge difference from the standard mouthpiece.


I have bought three Seacure Mouthpieces

By taco

Best buy I have had three sets over the past ten years both the wife and I and no regrets.


you can not believe it.

By bawana

promt on time



By taco

Very easy to get ready just put in warm water, warm enough to soften but not hot to burn yourself, then follow the instructions, Be sire to get the correct model for regulator. Check the Leisure Pro site to match model with regulator.


End Jaw pain

By Mike

Do not doubt this product!!!! If you think it may not work for you, try it anyway. You will like it.


Denture Substitute

By TomG

I have 3 pins in my lower jaw which support my partial denture. When I mold the mouthpiece, the pins create three small holes which create a snug fit. I do the same process on both my regulator and snorkel mouthpieces. Works great.


Awesome Product


The sizing chart is incorrect. If you have a Scubapro S600, it is a size 2 NOT a size 1. Every chart, including Sea Cure's website, said it was a size 1, however, when I got the mouthpiece, there was a size chart inside the package that listed the S600 as a size 2. Of course I contacted Leisurepro and their top notch customer service got me a new mouthpiece and since I was headed on vacation, they shipped it next day air no charge. Got it and it fit just fine. Leisurepro service is INCREDIBLE.


Seacure the Best

By IDiveanywhere

Great product. Don't ever want to dive without it now! Spoiled rotten from this product. Please don't ever discontinue selling these. If you don't have one, get one! Cheap and can be remolded multiple times.


good product

By Ertle M.

great product


Great fit and feel

By Mcinnisp

Great fit, very comfortable and helps reduce jaw fatigue while diving. Well worth the price.


works well

By george p.

easy to use and comfy!


superior to standard mouthpiece

By DiverDan33

SO much better than any standard regulator mouthpiece I have ever used. Greatly reduces jaw fatigue. Follow the directions and you get a very comfortable and customized piece of dive gear. Love it and hope to never have to dive without it.


Questions & Answers

Questions about this item:

Shopper  Why Did You Choose This?
JOHN H  durable
JAMES J  My wife has used these for years. Recently, my mouthpiece started irritating my gums a bit, so I'm getting one for my rig.
B R  new item that might help with tmj and jaw problems. I have a big mouth for talking but small mouth for scuba gear. so this looks like it will be helpful.
Carl F  Used this product previously
Dan D  This customizable mouthpiece greatly reduces jaw fatigue. Very comfortable, and highly recommended. To conform it to your mouth place it in very hot water for a few seconds then bite onto it.
Hanford G  i wanted a new mouthpiece because i was having a sore jaw...problem was the material was still a bit too hard after molding and it rubbed my gums raw...ultimately i changed it for for a softer mouthpiece.
MARTIN M  Custom mouth piece is the only way to go when diving on multi-dive-day trips. (I've logged 100's of dives on these)
Ken K  Reviews sounded good and I got it for my wife. We went to the Philippines for 10 days at the end of August '14 and she didn't have near the jaw fatigue with it.
Frank M  awsome mouth piece.
ScubaDue S  Thought it would reduce jaw fatigue but was a little too long for my mouth and still slipped out of my mouth when air hose tugs... so went back to my first replacement that has the "retainer like" flap that fits behind top teeth...that is still the best I've found.
RICHARD S  I verified that I have the proper size, but the mouthpiece is too tight and stiff to install on my TUSA regulator. This is acknowledged in the instruction manual, but no recommendations are provided. Can anyone help me with specific suggestions?
Dannori D  Try some dish soap or cooking oil to ease the process.
Ken K  You might try putting the end that goes on the regulator in very hot water, not boiling, to make it more pliable, much like you do to make it form to your teeth.
DARRELL B  If indeed you have the correct mouthpiece for your reg., then just warm up the mouthpiece for about 5-10 seconds in boiling water, and then fit it to your regulator. It should go right on.
RICHARD S  This worked! Thanks.
Michael F  What size will fit a Zeagle Envoy II regulator?
Ronnie R  SeaCure’s sizing chart says to use size 4 for Zeagle regs.
