4-Pack Silicone Bite Valve Replacement Nozzles Compatible with Osprey Hydration Bladders, Hydraulics Bite Valve Replacement for Water Reservoir

Great replacements.

Great to add onto your regular tap, but does not slow water.

Fits well and doesn't leak, but has a lower water flow rate than the original

Just what I needed

Work good but material is harder than the original Osprey bite valve

Used this to replace the nozzle on my Osprey hydration pack which had a tear in the plastic. The plastic on this nozzle, however, is much tougher, I used it for a 5 day hiking trip and had only minor issues where the outer clear plastic separated from the red but i was able to push it back together without issue. So far i am happy with the value and the quality of this replacement nozzle, i expect it to last me longer than the OEM based on the quality of materials

If you’re not careful the inner red piece gets stuck open and dumps water.

I got these because my old mouthpiece was getting gross and moldy and i was not able to get it fully cleaned. This was to replace the bite valve on my 3l Osprey hydration sleeve. As you can see from the pictures it is a close match to the brand name one. It is not exactly the same, but close enough that it fits pretty securely. The outer material that you bite down on is a bit less soft than the brand name one, but it is not so hard that it is a problem. The original has a matte finish, and this replacement is smooth, but that doesn’t affect it much at all. The one big issue I had with this is that the center section keeps popping out slightly which causes the water to leak out. I was able to push it back in and get it more secure, but it has happened twice so far, so clearly this is an ongoing problem. To be fair, I do take this into pretty intense hiking adventures and it can get beaten up on those trails. Overall, these are a decent replacement and if you are not scrambling up mountains and pushing through scrub brush where your bite valve is getting bumped around a lot, then yours probably wont have the issues I faced with the center popping out on occasion.
