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

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!

Responded on

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.

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.

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

does the job

  • Gender: Female
  • 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!

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.

Is there any problem with using the hydrolink...

Is there any problem with using the hydrolink filter adapter with the ergo hydrolock bite valve to pump into the reservoir

Responded on

No problem at all installing it in-line, although if you're asking if the male adapter plugs into the end of the HydroLock itself, no it doesn't.

Must Have

These things are constantly sold out and IMO should come standard on the CamelBaks. I hate having the bite valve drip and these solve that problem.

Easy to install and worth the money.

Stops the drip (or stream)

These keep selling out, and probably for a good reason! If you are as sick as I was with getting water running down your bike and ski and whatever gear, do yourself a favor and pick one of these up!

I will state that I haven't had any issues with freezing, but I use this product with a pack that has a sleeve to keep the tube warm. The sleeve wont accommodate the 90 degree angle, and the bite piece, but no biggie, I just leave the bit value sticking out a bit, and still the lock doesn't freeze up!

Drippy No more

This is the perfect remedy for my old problem of my hose spraying every time it hit my knee when I am biking. There is no question of any spills. It would be better if the valve itself was leak proof and didn't need this switch but nothing's perfect.

good bite valve

i have two camelbaks,one with this valve and one with the standard. and i will say i FAR prefer this one, the standard leaks all the time (often into my armpit making me wonder why im sweating on the right but not the left!) but the lock on this one solves that problem ALMOST compleatly, i find if you lock it first then suck out the rest of the water in the rubber bite part you wont have any dribbles at all. i am frustrated though that the yellow locking mechanism on mine is starting to pop out, each time worse than the last and draining a good portion of my water out and onto me. but its worth saying that mine is many years old and for the couple bucks it takes, ill just get a new one.

great alternative to the big bite

Gotta love a locking valve that is easy to manage. Bare handed or gloves the hydrolock is easy to manipulate and keeps leakage to a minimum. Used this as a replacement after my lab puppy chewed up my other one.

I like Camelbak, but...

I have been a Camelbak fan for a long time. I have played with generic reservoirs and they don't hold a candle to the camelbak quality, but I have had trouble with this specific piece. I love the idea and they start out great, but after two failures with the hydrolock I'll avoid it.

After a lot of use one of them began to leak from from the yellow valve. Without much use at all the other piece became completely useless when the yellow valve became so loose that it would just fall out while walking, causing the water to gush out in its place.

The whole concept is to prevent water from coming out when you don't want it to, but I have found that I leak more water with the hydrolock than I do without.

Must Have

Bite valves always tend to leak a little bit. This helps provide a secure way to shut off the flow of water while using or while transporting. It really sucks showing up to the trail head to find out all your stuff is wet and your out of water. The right angle also makes it easier to drink from on long rides or hikes.
