HydraPak Comet Bite Valve Hydration Drink Valve (1/4" Diameter)

My old one got moldy and this was a great replacement!

Fit perfectly in my old knock-off Camelbak. Good flow, doesn't leak either.

Was a little small just heated the end of the tube to fit and have not had any problems

This adapted perfectly to my water pack! The shut off valve works great, and the bite piece is extremely good quality, I would highly recommend purchasing for anyone looking to replace their’s. Installing it was extremely easy as well!

The most important feature of this valve is the stem that sits inside the silicone sheath. The HydraPak stem is designed to maximize the flow by providing the most clear space that it can. No-name knockoff stems that I have used have four smallish holes that restrict the flow. Many currently on offer have 7/64 inch holes that provide low flow. An older CamelBack stem that I have has 9/64 inch holes, and provides adequate flow. The HydraPak has holes that are expanded to a triangular shape and flutes that are a simple cross that provide very good flow. After using this valve, I bought some HydraPak replacement stems+sheaths to upgrade my old valves to the HydraPak flow rate. Note that the replacement sheaths come in two lengths; get the one that fits your valve body if you want to upgrade. Otherwise, you will have to use your existing sheath with the new stem, which is OK, but then you don't have a spare sheath. I prefer the slightly angled geometry of this valve as it is easier for me to grab and hold in drinking position. Valves where the body twists 90 degrees to open the shutoff have an offset that I find awkward. The HydraPak shutoff doesn't interfere with the valve layout, and is also much easier to clean as a small brush can fit through the nearly straight opening. This is packaged in a small box rather than a plastic bag. All of the bite valves I have take the same hose size as the HydraPak. I use silicone tubing with 1/4 inch internal diameter and 3/8 inch outside diameter. I have never had leaks with this. I don't like vinyl tubing because it is too stiff. While the silicone tubing can kink easily, it also does not take a set and un-kinks just as easily. In cases where my routing makes the setup prone to kinks, I insert a length of 0.08 inch string trimmer line through that section, which prevents kinking.

Larger / bulkier than expected.

Shut off valve breaks easily - especially in cold weather conditions. Fit is perfect in my hydropack and works as intended. Maybe they can redesign that shut off switch so that it doesn’t break.

Used to replace on my bladder I use for running.. easy to install and no leaks

Original bite valve failed after about 10 years. Replacement works well and has a tap. Relatively easy to remove old and install new valve using hot water to soften tube.

Spot on, I broke mine in the car door, this went on without a fuss

Simplemente lo mejor en su tipo Hydrapack es exelente. Los materiales son de lo mejor y la tapita muy útil e igienica sobretodo
