Sawyer Products SP110 Inline Hydration Pack Adapter for Screw-on Filters Blue/Gray ,One Size

The Sawyer Products SP110 Inline Hydration Pack Adapter for Screw-on Filters is a versatile and useful tool for making a DIY filtration system. It can connect to a Sawyer Mini with the appropriate tubing and fit almost all water bottles. The gray adapter can fit the larger end of the Lifestraw and can be secured with electrical tape. Though the blue adapter doesn't seem as heavy-duty as pictured, it works just fine. However, some reviewers stated that the blue connector can come loose and drain water, or leak even when using multiple gaskets or plumber's tape, creating a potential loss of water. The product is a bit expensive for what it's worth, but it can be useful for those who want to create a gravity filtering system.
