Henry ★★★★★ Oct 11, 2026

These are the exact parts to keep my filter working for another season. The new gasket seated perfectly and I had no leaks after reassembling. Everything fit just like the originals.

Ruby R. ★★★★★ Sep 15, 2026

The replacement O-ring and valve fit my filter like they were made for it, which they basically are. I've been using this filter on every backcountry trip for three years and it's nice to know I can keep it running instead of buying a whole new one.

Swapped in these parts before a week-long trip and the filter sealed up perfectly, no leaks or slow pumping. It's a relief that the pieces click in exactly like the originals.
