Maintain a leak-free and efficient water filtration system with the Culligan OR-360B O-Ring, specifically engineered for the HF-360B 3/4" Whole House Water Filter Housing. This essential sealing component ensures a secure connection between the filter housing canister and cap, preventing water leaks and preserving system integrity.

Key Features:

• Precision Fit for HF-360B Systems
  Designed to fit Culligan’s HF-360B whole house water filter housing, the OR-360B O-ring forms a tight seal between the canister and the cap, ensuring leak-free operation.

• Durable NSF-Certified Buna-N Rubber
  Molded from NSF 61 certified Buna-N rubber, the O-ring offers excellent resistance to compression, temperature fluctuations, and chemical exposure, making it safe for use with drinking water.

• Recommended Maintenance
  Replace the O-ring every third filter change or immediately if signs of wear, cracking, or deformation appear. Regular replacement helps prevent leaks and ensures optimal system performance.

• Easy Installation
  Tool-free replacement—simply remove the old O-ring, clean the groove, apply food-grade silicone lubricant (optional), and insert the new O-ring for a secure fit.
