The Aladdin O-542 is a direct aftermarket replacement for the Hayward CCX1000G tank body O-ring, designed specifically for the Hayward XStream CC1000, CC1500, and CC2000 Series cartridge filter tanks. Measuring approximately 16 inches in diameter with a 0.275-inch cross-section thickness, this large O-ring seats between the filter tank body and lid to create a watertight, pressure-resistant seal during filtration. A worn, cracked, or deformed body O-ring is the most common cause of water leaking from the tank lid seam — replacing it is typically the fastest and most affordable fix for an otherwise fully functional XStream filter. Molded from OEM-specification synthetic rubber without spliced or glued seams — a common failure point on lower-quality O-ring replacements — the Aladdin O-542 delivers reliable, long-lasting sealing performance at a fraction of the OEM part price.
- Direct Replacement for Hayward CCX1000G: Engineered to match the exact dimensions of the Hayward CCX1000G factory O-ring — approximately 16 inches in diameter and 0.275 inches thick — ensuring a precise, properly seated fit on XStream CC1000, CC1500, and CC2000 Series cartridge filter tanks.
- Fully Molded — No Spliced or Glued Seams: Unlike lower-quality O-ring replacements that are spliced or glued at the ends, the Aladdin O-542 is fully molded from a single piece of synthetic rubber — eliminating the most common structural failure point and delivering a more reliable, longer-lasting seal.
- Stops Lid Seam Leaks Fast & Affordably: A degraded body O-ring is the leading cause of water leaking at the filter tank lid seam — replacing the O-542 is a quick, low-cost repair that restores a watertight seal without the need for professional service or full filter replacement.
- OEM-Specification Synthetic Rubber Construction: Molded from pool-grade synthetic rubber formulated to resist continuous pool chemical exposure, water pressure, and UV degradation — maintaining its sealing performance and elasticity across the full pool season without hardening, cracking, or compressing out of shape.
- Compatible with XStream CC1000, CC1500 & CC2000 Series Filters: Confirmed fitment across the full range of Hayward XStream cartridge filter models — always verify with your filter's parts diagram that CCX1000G is the correct O-ring for your specific model before ordering.
