Service life is up to 2-3 years, longer than ordinary rubber O-rings
• 【Leak-Proof Seal】: The 3.75" inner diameter and 0.14" thickness are engineered to fit filter housing grooves tightly, creating an airtight seal that stops water leakage, pressure loss, and unfiltered water bypass. Each pack includes a dedicated installation tool: it easily pries out old, stuck O-rings without scratching the housing, and helps press new O-rings evenly into place—avoiding misalignment. 3-pack design meets immediate replacement and spare needs
• 【Easy to Install】: No professional skills or extra tools required. Step 1: Turn off water supply and relieve filter pressure; Step 2: Unscrew the housing, use the included tool to remove the old O-ring; Step 3: Clean the groove, place the new O-ring, and press it firmly with the tool to ensure tight fit; Step 4: Reassemble the housing and restore water supply. Even beginners can complete installation effortlessly
