O-Ring Set for RO Housings - 7 Pieces
Keep your reverse osmosis water filtration system running smoothly and completely leak-free with our comprehensive 7-Piece Replacement O-Ring Set. Over time, factory Orings can wear down, stretch, or pinch, leading to frustrating drips under your sink. This complete kit provides exactly what you need to securely reseal your RO housings during your next routine filter replacement.
Package includes:
- 6 large O-Rings (3.5") for the three pre-filter housings (two O-Rings per housing)
- 1 small O-Ring (2") for the RO membrane housing
