Sawyer ProductsSP110 Inline Hydration

I used the Sawyer Products SP110 Inline Hydration Pack Adapters, and a 3 foot section of silicone food-safe tubing and a CNOC water bag to make my own gravity filter system. With the right adapters, this is simple and hopefully will save me effort of squeezing on those filters. I have a Platypus Quickdraw; it should also work with the Sawyer Squeeze or any filter that connects with a 28mm water bottle. I am attaching the filter at the BOTTOM of the tubing so there is more water pressure pushing through the filter (this means the tubing is on the dirty water side of the system). I am optimistic this will work and I'm going to test this out on an upcoming backpacking trip.The only con is that there is no barb on the blue end 1/4" connector. The silicone tubing I have seems to hold on anyway.

I used the blue end to adapt the outfeed hose of my Katadyn Hiker Pro filter so that it would connect directly to the 28mm threads on a Hydrapak collapsible water bottle. It works perfectly for this application. As others have noted, there is not a barb on the blue end, only the grey end, but the Katadyn silicone hose slips on easily and holds securely — a non-issue.

I purchased this to use with my MSR dromedary cap. The dromedary caps technically have a tap on them that you can use for rinsing dishes or a toothbrush and filling cups/bottles, but the flow rate is very slow, and it's easy to waste a bunch of water just based on how it works. I really wanted to be able to adapt my cap to use standard hydration hoses, and this cap did the job. Admittedly, I only purchased this to use the blue cap with female threads, but it has worked great on my dromedary cap. It looks like most manufactures use this thread size or have a way to adapt to it, so if you're needing to be able to adapt to a standard hydration hose, this is a good option. It even has a hose washer in it to prevent leaking.One thing I did notice was that the blue cap does not have a barbed adapter as pictured. It is smooth, but tapered. I am a little concerned about leaking or about my hose coming loose over time. If that happens, I suppose I'll just put some fresh hose on there. It is working great for the time being, but it is not as pictured.

I am using these products for a different application than most. These two components are going into my bug out bag. The gray end with male threads will be used as a cap for my Saywer Mini. I simply used a pliers to bend the end together and then melted it closed over a candle. I want my Sawyer Mini capped after use so that potentially contaminated water does not get all over my water preparation kit and cause cross contamination. I would rather be safe than sorry in this regard. The male threads fit right inside of my Sawyer Mini. I am also carrying a couple of standard soda bottles in my kit. They are lightweight and durable. One is for collecting water (green Mountain Dew bottle) and the other is for water I made safe to drink. The blue adapter threads onto the clean water bottle, and I attached small piece of the straw that came with the Sawyer Mini to the adapter. That is the device I will use to back flush my filter in the field. As far as others using these filters to make a gravity feed system, I am can do the same thing by simply threading my Sawyer Mini to my dirty water bottle or use it like a Sawyer Squeeze.

Works fine. Recommend.Use with Katadyn BeFree to connect output hose to make filling water containers easy.

I got this to create a DIY gravity system for my cnoc water bag and Katadyn be-free filter. These worked perfectly for me!

good for a piece of plastic, but the nipple lacks a retaining barb to keep a hose on, had too resort to using a zip tie.

I already have a pair of these from a sawyer filter set I bought in the past. They work well with my Osprey hydration pack, as there is a quick release piece on it that I take off, and put these on to use my Sawyer filter with it. When I don't need the filter, I just screw these together and continue to use the hydration tube. Since I have more than one hydration pack, having a few of these, comes in handy to use on them.
