Replacing Your Housing O-Ring

  3. Lightly lubricate the new Watts S7966-1 O-Ring with food-grade silicone grease

  5. Reinstall the housing sump, hand-tighten firmly, and slowly restore water pressure while checking for leaks
COMPATIBILITY

Fits These Filter Housings

The Watts S7966-1 O-Ring is designed for Watts and Pentair full flow filter housings in both 10-inch and 20-inch configurations. This includes standard 3/4" and 1" inlet/outlet full flow housings commonly used in whole house water filtration systems. Verify your housing manufacturer and size before ordering, as standard and slim-line housings use different O-ring profiles.

🔧 Pro Tip: Keep a spare O-ring on hand and replace it any time it appears flattened, cracked, or loses elasticity. A compromised O-ring is the most common cause of housing leaks, and replacing it during routine filter changes prevents unexpected failures.
