Standard replacement

  • Familiarity: I've put it through the wringer

My camelbak is an old one, I bought it 7 years ago, so I was afraid that I could not find a replacement to fit on it, but happily it is still being the same one :)

Glad to keep the pack in service

  • Familiarity: I've put it through the wringer

Lost the lock on a tree I think and thought I'd be buying a whole new bladder. So glad that Camelbak keeps parts available! Cheap way to keep this old pack in use!

Does the job!

  • Familiarity: I've used it several times

My original valve broke on me, and this is a perfect replacement. Fits right on the original hose without any issues. Pick one up!

Thanks Camelbak!

    Happy that Camelbak makes universal replacement parts. My 5 year old bladder lost the hydra lock, and now I can fix it for just a few dollars.

    Great for turning the water off!

    • Familiarity: I've put it through the wringer

    This little L clamp is what you need to transport your already full camelbak to keep it from leaking all over the place when the bite valve gets pinched. Happens all the time, unless you have this to close off the water hose. Also comes in handy if your bite valve does start to leak and you don't have a replacement. Nothing worse than all your water running all ver you while biking or hiking. Simply shut the water off.


      Solid little piece of plastic that allows you to totally shut off the flow to your camelbak. Perfect for when you are in the car, or just dont want to risk losing any precious drops.


      • Familiarity: I gave it as a gift but have feedback to share

      Got this as a replacement when my girlfriend accidentally stepped on hers and cracked it. It does what it was intended to do.

      Top Notch

      • Familiarity: I've put it through the wringer

      Per usual, CamelBak is coming through with solid material that lasts forever at a reasonable price. My last Ergo Hydrolock lasted almost ten years and only stopped working when I accidentally bit through it. After replacing the piece at a steal of a price, it works incredibly well and like always locks/unlocks with no problem. I look forward to many years and trails blazed using this piece!

      Nice Replacement

        Its nice that CamelBak sells cheap replacement parts for their bladders. Similar to other users, I had a leaky valve and didn't want to have to buy a whole new bladder. I picked up a new one of these and was back in business! Easy to change to get a few extra miles out of the perfectly good bladder.

        Adequate, not the best.

        • Familiarity: I've put it through the wringer

        I've used CamelBaks with this Ergo Hydrolock for years and they've worked well. Occasionally the yellow piece has popped off or snapped in half, which I chalked up to just being well-used. But then I tried the larger Hydrolock and realized how inferior this piece is.

        This hydrolock is smaller which isn't necessarily bad, but its not as durable and comes off a lot easier than the larger Hydrolock knob. For only a few dollars more, I enjoy the peace of mind that comes with the larger knob, knowing that everything will stay attached and I will not lose all my water when I'm several miles into the backcountry.

        it's so simple

        • Familiarity: I've put it through the wringer

        I had a leaky bite valve, so I replaced it with this. problem solved.

        It won't go on

        • Familiarity: I've used it once or twice and have initial impressions

        I have a relatively old Camelbak (100 oz, maybe 8 years old) and along with the insulated tube is an internal liner. It's a flimsy hose running inside the main water flow tube. When I try to put on the hydrolock, it pushes this liner down the hose instead of going around the end of the hydrolock, rendering the Camelbak ineffective. I'm putting the barbed side into the hose (like it's supposed to go, I think), and I can't get the hydrolock on. It seems like everyone else is saying it's really easy to put it on -- is this just me, or do only old Camelbaks have these inside liners? Any suggestions? I've tried dish soap and warm water, and neither work for me. Thanks!

        Try cutting the tube as cleanly as possible at least 1/2 inch below the bunched up inner tube and try again, taking care to use lubricant, like rubbing alcohol or warm soapy water. If the problem persists, contact the CamelBak warranty department about the possibility of getting a replacement tube.

        What is the diameter of the connector end of the CamelBak Ergo Hydrolock?

        Best Answer

        The Inside diameter of the tube connection end is approximately 0.195" the min outside diameter of the barbs is about 0.285" and the max. outside diameter of the barb is about 0.310".

        Fixed the leak

          Got this to replace the old model valve that started leaking. The new movable lock valve on this system is great. Works exactly the way I wanted. Camelback gets my vote over other hydration systems.

          exactly what I wanted

          • Familiarity: I've put it through the wringer

          Getting tired of an awkward to get at drink tube? This will solve the problem for you!

          does the job

          • Familiarity: I've put it through the wringer

          Thought I lost mine, bought this as a replacement. Does the job, and it is wonderful to be able to lock it. I have left it unlocked before, and my backpack will find its way on top of it, put pressure on the valve and it leaks. So it is great to have the option to lock it.... if you can remember to!

          Unanswered Question

          Don't they still make the straight Ergo...

          Don't they still make the straight Ergo Hydrolock valve by camelBak they tend to be alot easier to operate....

          It's okay.

            It does the job, but the water valve is counterintuitive. In other words, when the valve is lined up and flush with the marker it is turned on. When the valve isn't lined up and the tab is turned to the side and susceptible to being bumped that is the off position. I would have designed it so that the valve is easier to be visually noted as in the off position and less able to be bumped and accidentally turned on. Also, the construction is very cheap for a $6 item. I have doubts about it's long term service life. I guess you are still paying for the Camelbak name, even with this little valve.

            Freaking amazing!

              I just love this, if you don't have one, get it! Nothing worse than bending down to fiddle with a ski boot and winter and getting drenched by your camelbak, NOTHING!

              As for issues with freezing, I always open my bit valve up with my hand after I am down, and raise it above my head, this gets most of the water out f the lock area, the bite valve, and out of the tube, the places it is most likely to freeze in. Alternative to that, I make sure and take a sip on every chairlift, or every few hundred yards skinning, keeping things from freezing up.
