Does what it is supposed to

    I have this on my old Platypus Big Zip which it was designed for. I added it to the new Big Zip because of the bad reviews of the new, rounder valve cover.

    Great Addition, But A Pain To Install

    • Familiarity: I've put it through the wringer

    Every hydration pack should come with this little cover. What's worse than dropping your pack and getting your bite valve covered in dirt/mud/muck? Not much... This thing was a pain in the butt to get onto the tube, mostly as the rubber of the bite valve doesn't move easily.

    Great Addition!

    • Familiarity: I've put it through the wringer

    After having too many complicated hydration bladder, I transitioned over to using the Platy Plus bags w/ drinking tube & the Hoser Hydration for their simplicity! This bite valve cover was a must have for the simple design of the Platypus drink system! It was not the easiest install, but that just means that it will likely not leak or come off anytime soon. If you are getting on the Platypus hydration or already have one of their drinking tubes, this is a very worthwhile accessory to make that wonderful agua taste that much better on the trail as well as keep that dirt out of your teeth!

    Very Necessary Accessory

    • Familiarity: I've put it through the wringer

    Unless you enjoy dirt and grime on your bite valve and in your mouth I'd say this is a great accessory for your Platypus bladder. On a trip last week I was with a friend that had purchased the Platypus Big Zip LP Hydration Bladder and didn't get the bite valve cover. After only one time of setting his pack down and getting dirt all over his bite valve he was wishing he had spent the extra few dollars for the cover.

    Three cheers for a clean bite valve!

      Love this product. I found it while looking for a replacement part for my Platypus, and knew I needed this as soon as I saw it. Easy to install and does it's job. With how often I throw my pack on the ground only to find the bite valve covered in dirt...well, this little guy is going to make me a much happier hiker.

      Just what I needed

        On my last backpacking trip, after trying to keep my Platypus bite valve from sticking straight into the dirt every single time I put down my pack, I knew I had to get one of these. I guess it's not all that necessary for day hikes or short outings, but on longer trips it's essential. Installation is easy, and it seals well. I'd definitely recommend this product for Platy users.

        Works great with the shut off valve

          I recently purchased a Platypus Big Zip, which comes with the shut-off valve already on the hose. This cover can be used with the shut-off valve.

          To use the the cover with the shut-off valve, remove the bite valve from the shut-off valve. I twisted back and forth while pulling. It's jammed in there good and looks like one piece so I wasn't sure if it would separate, but it came off without incident.

          Next, put the bite vale into the cover as far as it can go. Mine poked out the bottom of the cover by about a millimeter. Then twist/shove the bite valve back onto the shut-off valve. Pushing by the cover was a failure, it simply pushed the cover off the bite valve. Try pushing against the bite valve to push them back on the shut-off valve.

          Voila! No more setting the mouth piece down on trail manure.

          This is the same mouthpiece included with the Platypus hose insulator. So if you are cheap like me, a walk to the hardware store nets the insulation for a couple bucks.

          Works great with the shut off valve

          Does anybody know if you can install this...

          Does anybody know if you can install this on the Platypus Platy SoftBottle?

          The softbottle has a hyperflow bite valve (see pics on the softbottle page) but the mount is different than the one in the YouTube video.

          Has anybody installed the bite valve cover on the softbottle? Is it possible?

          Looking at the pictures, it looks like the tube is attached to the screw on/off part, so I don't think it will work.

          Best Answer

          Yes you can. Just pull off the bite valve.

          Easy Install - Good Fit

            First, install is easy. Pull off the bite valve at end of drinking tube[pull out from tube], slide this cover on, then push the bite valve you just removed back into the drink tube, slide the cover back down around the bite valve [a little tight wedging it down but gently nudge it till it fits], and snap it closed.

            As to utility, seems the right thing to do to keep dirt and debris from mucking up your bite valve when wearing your hydration pack. Looked good after it was installed. If cap is fully pressed into the lower part, it sealed well.

            Unable to field test it yet, but see no reason it would not provide adequate protection.

            can someone add a picture where its attached...

            can someone add a picture where its attached to the Big Zip SL? Not sure how to get it installed (pathetic, I know).

            Best Answer

            I've made a video on how to do so:

            After watching the video it certainly is easy to do. I guess I just didn't want to seemingly take apart the valve itself without knowing that it does indeed detach. THANK YOU!

            For anyone buying the platty bladder, definitely get the cover. Goes on easy, if you know how to do it.

            Platypus Bite Valve Cover

              I just came off a three day trip into the back country of the Sierra Navada mountions. It was the first time that I used the Platypus system. For me, it was very convenent not to have to pull a bottle out from my hip belt. I liked this a lot. However, when I am huffing and puffing up the side of a peak, I tend to stop and allow my heart rate and breathing to come back into normal range now and then. When I did this, it was too easy to suck on the platypus while i was sucking air. This did not work well for me. Water and air are not interchangable. Ah, but that is just me.

              I did notice that the valve cover came off a few times. This would happen both while I was hiking, so that was no problem, but also when I would set my pack down in the dirt, where it did become a propblem. I would then have to retrive a water bottle from my hip belt to clean off the month peace of my platypus, hum... Perhaps Platypus could make this just a little more secure.

              Over all, I enjoyed the system and was glad I bought it along.


              I have had the same problems with the Camelbak valve cover coming off now and then. The manufacturers just can't seem to get some things right.

              It's probably obvious but sadly not to...

              It's probably obvious but sadly not to do I install the cover over the bite piece?

              Best Answer

              smaller end with tapered tubing slides onto the tube, post removing the end piece from the tube, re-attach end piece after Platypus afterwards

              I made a video on how to do this here:

              Finally a real cover from Platypus!

                I love the Platypus Hyperflow valve - but switched to a Camelbak Big Bite valve (almost as good) only because it had much more effective cover...

                Well things have changed - the new cover brings Playtpus up to par. I still prefer the Camelbak valve cover slightly - its smaller (so's the bite valve) and seems to stay on just slightly better under abuse...

                However the platypus seals very well (in all normal use) and also has a little hole which you can use to hook it to your pack strap.

                So now I'm using the hyperflow bite valve with this new cover. Note that Platypus sells this as a duo pack with a new insulated hose cover (improved materials)...

                Cover my valve!

                  I just installed my platypus bite valve and i love it! I always found myself drinking sand with my water. This has corrected that problem! I recommend this to anyone! Installation is a breeze, and the cap snaps on what more could you ask for. It is the simple things that can make you miserable on a trip.

                  How the heck do I get the bite piece off the tubing. I have pulled straight, twisted and turned and used hot water on the tube. I am glad it's secure, but if I can't get it off at all, I can't clean properly or get the valve cover on. Any suggestions?

                  Great accessory!

                    This is the best invention ever!! I was dragging my mouthpiece through everything and was getting very reluctant to use it. The cover prevents the mouthpiece from getting covered in dirt so all you get is water! My only complaint is that the cover seems to pop off easily when snagged on something.
