Solid mouth piece

  • Familiarity: I've put it through the wringer

My old one ripped so I'm glad they had replacements! Fits very snug and works great

Another lost mouth piece

  • Familiarity: I've used it several times

Very happy to find a quick replacement after losing my mouth piece!

Quick and easy!

    Had to get a replacement for my mouthpiece when I lost it camping. Super easy to use, works perfectly

    Simply Necessary

    It's one of those items that you need to have working properly. I just replaced my bite valve because it was cut and leaking all over the place. Simple replacement and I'm ready to roll again. Perfect fit as always.

    Just what I needed.

    • Familiarity: I've put it through the wringer

    The original fell apart, and this replacement is just what I needed.

    Replace it

      They don't last forever, but think about the torture you put it through. You bite it, pull it on and off to clean it, toss it in the back of your truck for a week in the hot sun or freezing cold. It's best to have the mindset that this is a consumable part.

      Replace it

      Good Mouthpiece

      • Familiarity: I've put it through the wringer

      These work really well. Water flows well when you want, they don't drip (too much) when you don't. They do not last forever, but they are also 6 dollar pieces of rubber so that is kind of what I expect.

      Decent durability

      Picked up a couple of these to replace the aging bite valves on reservoirs that my wife and I use pretty regularly. I'm happy with how long these last before starting to get funky or leak - we had one that started to leak after about 4 years and another that fell victim to an over-zealous rodent on a recent backpacking trip. These are easy enough to clean - I usually just rinse with hot water, only occasionally use soap, and make sure to take them off the hose to fully dry. I've gotten mildew in them on occasion, but a quick flush with soapy water takes care of it. They have a bit of a rubber taste when brand new but I've found that it wears off after a couple uses.

      Can this mouthpiece fit the Nathan Sports...

      Can this mouthpiece fit the Nathan Sports Intensity race vest? I am reading differing tubing diameters appears that my Nathan tubing is 10 mm OD (eyeing it w/ a ruler)...but I've read CamelBak's tubing is smaller. Can you verify that this mouthpiece will fit 10 mm OD tubing? And has anyone successfully used this on a Nathan Sports race vest?

      Best Answer

      Lindsey, I put a Camelbak valve on the tube of my Nathan HPL #020 hydration vest and it works great. I just pulled it off an older Camelbak reservoir I had when the Nathan valve broke. (The Nathan valve is a DAKINE valve and, in my opinion, is pretty worthless.) The Camelbak valve I put on was not the Big bit valve. It was one with an insert that slides into the tube. It works great so I am guessing the inside diameters of the Nathan and Camelbak must be pretty close - close enough that the Camelbak valve fits snuggly with no issues.

      My brothers Big Bite Mouthpiece broke after a few years of extended use and needed a replacement so I got him this one. Works great! Put some "special" lube on the hose and let it slide right into the mouthpiece and let it dry. ;)

      It dun broke

        I had a camelbak for several years with the bite valve and it worked great for a few but right as I hitting the trail a while back it broke. It kinda cracked in half like it had been soaked then dried one too many times. not sure if I didn't follow some sorta maintenance thang, but anyways I recommend a valved mouth piece. PS it leaks after a while as well.

        May or may not be an improvement

          I got this thinking it was better than the one that came on my new Camelbak, but I think its the same. No big deal, not bad to have an extra.

          Solid Replacement

            Even though camelbak bladders work so well, eventually the mouthpiece will wear out and leak. Instead of buying a whole new camelbak reservoir, this big bite valve mouthpiece is the perfect solution. I recently carried an extra one with me on a week long hut ski trip.


              If you use your camelbak a lot, the mouthpiece wares out and starts leaking... this solves that problem perfectly!

              Bite valve seems completely sealed shut

                Just got a Camelbak Groove water bottle and the bite valve seemed to be completely sealed shut with no opening. Tired to bite on it, and suck out the water like you're supposed to do, but nothing...slit it open with a knife, but that was a very bad idea because it caused the bite valve to leak water when turned upside down. Returned the whole bottle, and got a new one. Same problem! This time, however, I took the bite valve completely off, and soaked it in a glass of very hot tap water (not boiling, just hot from tap) for about 20 seconds. Then I squeezed it together, and voila, the bite value opened right up! Now I love my new Camelback Groove water bottle--delicious, filtered water!

                Thanks a million for the tip, you just saved me the trouble of sending the bottle back and waiting for a new one only to be disappointed again. Your hot water trick worked like magic and now I'm super happy with my new 1L Eddy bottle :D

                Great Replacement!

                  Sometimes you need to replace the mouthpiece because you somehow got a hole in your old one and it is leaking all over the car and on the trail! Buy this replacement mouthpiece so you don't have to buy a whole new bladder! Use some adult lubes to easily slide the mouthpiece onto the hose. You know how its done! ;)

                  I just bought a new camelbak 750ml bottle...

                  I just bought a new camelbak 750ml bottle with the flip valve. When I took off the plastic on the bit valve I see that the bite valve has no slit... is this a defect that commonly happens? Am I supposed to cut this myself? I dont' have the receipt and already took off and threw away the tags, washed it and filled it with water before I notice so not sure I can return it now.

                  Bite valves come that way, just chew on it carefully and it should split open normally.
