MSR AutoFlow Nalgene to HydraPak Seeker Adapter

thingiverse

I'm obsessed with my MSR gravity filter and HydraPak Seeker bags, but one crucial piece was missing - a seamless connection between the two. The pressure fit would loosen up at the worst moment, causing my boots to get soaked by the entire contents of the bag. That's why I invested in this adapter, which boasts male fittings compatible with wide-mouthed Nalgenes that MSR proudly supports, and female threads designed specifically for 42mm Seeker bag spouts. Once both sides are securely locked in place, you can essentially set it and forget it - no more worrying about leaks or spills. Moreover, back-flushing is a breeze without the risk of the entire bag pouring out onto the ground.
