Products SP150 Coupling for Water Filtration Cleaning, Blue, 1 x 1 x 1 inches

Sturdy little piece of plastic. I’ve taken this on one backpacking trip to date. I found this to be a perfect fit to join my sawyer filter with a smart water bottle (a favorite of backpackers); it seals well with no leaks. I would heavily recommend using a soft bag for your dirty water going into the filter, as this thing makes a good enough seal that you have to leave it a little loose if you’re feeding from a rigid bottle, otherwise the pressure is such that the water can’t move through the filter. As is, you’ll still have to loosen it every once it a while to let the air out of the receiving bottle. It’s small, simple, light, and a perfect addition to a compact sawyer filtering setup.

Works great.

Perfect addition to your water filtering system

Does exactly what it needs to.

This is a great little attachment for you Sawyer Squeeze. FWIW I use the normal sized sawyer, not the mini. This attachment lets you screw a regular waterbottle directly onto the output side of the sawyer squeeze, which lets you easily back flush your filter when it gets clogged and lets you easily set up a gravity filter system. By allowing you to easily back flush with this piece, you no longer need to bring the provided syringe to back flush on the trail. In my opinion, this should really be included with the filter when you buy it.

A MUST HAVE for the larger Sawyer filter (mini filter has NO output threads). As others have said, it allows automatic, hands off GRAVITY feed into collapsible plastic containers and they automatically shut-off when used right. MUCH better for back-flushing. CLEANING - BEST FOR ME . . . . I got rid of the syringe on this product and carry this much smaller, more effective Sawyer SP150 Cleaning Coupler. I mostly use it for filling 1 quart, collapseable, screw-top, plastic bottles. When they get full the flow automatically stops since it is sealed tight (air is removed before filling). Cleaning, then, is as easy as squeezing the clean bag after removing the dirty bag. It's SO easy, my filter gets back-flushed every use and it performs great, seemingly, forever. Hard plastic bottles with the same screw top have their advantage in camping and can also be used BUT MUST be coupled loosly to allow air to escape. After filling, tighten the clean bottle, remove the dirty source, squeeze the clean bottle to back-flush. Top off the clean bottle if desired. GRAVITY AUTO FILTERING With the Cleaning Coupler (SP150) and the Inline Adapters (SP110) and with some clear plastic hoses, I connected the filter to a Reliance 2.5 gallon collapseable plastic jug (wt 7.5 oz) !! Now with just one trip to the stream I have 2 1/2 gallons of drinking water available (after filtering) and the wide mouth of the "dirty" jug fills quickly. 3 or 4 ft of hose also allows a higher elevation for the "dirty" source and increases the flow considerably. As a bonus, the drinking valve that comes with the filter fit perfectly into the mouth of a second 2 1/2 gallon jug so I could get a full load of clean water with no work and no need to hang around and watch it. Water flow automatically stops when the "clean" jug is full since it fit so good. Same with screw-top collapsible bottles - screw one on to the filter with this Coupler, turn on the valve on the 2 1/2 gal jug and walk away - it stops automatically when full. I can fill my 4 x 1 Liter bags with less than 1 minute taken away from my outdoor fun !!

works as intended, do not buy knockoffs/fakes cuz they will crack when u screw them on, buy this instead cuz its made proper

I use this in conjunction with a CNOC Vecto for gravity filtering and it works perfectly. I’ve used it with a smart water bottle and a CNOC vesica and it fits great. Weighs next to nothing and worth it to gravity filter on backpacking trips.

使いやすいです！

Reviews are relative to each individual's experiences. I'm not an expert, but I do have a lot of backcountry hiking experience, and this product is a must have for an easy, hands free water filtration system in the backcountry. My system is like this: CNOC 2L bag for lake water Sawyer Squeeze Sawyer Coupling Smart Water Bottle (or any 28mm bottle) Attach everything in that order, hang your water bag on a try and let gravity do the rest. This hands free setup lets me do other things like setup my tent or eat while my water is filtering. I forget this at home one time and I was so annoyed having to hold the water bag while trying to line it up to the water. I'll never leave home without it again!

Beautiful and quality product. I advise.

Es un elemento casi imprescindible que debería venir junto con el filtro, de serie. Como el resto de accesorios que trae. Es una rosca de plástico, sin más que en una ferretería te costaría céntimos. Si quieres/tienes que apagarlo como yo, adelante.
