Hayward Body O-Ring CCX1000G OEM replacement for XStream cartridge filters — watertight seal, original spec

Hayward CCX1000G Body O-Ring is the OEM replacement seal designed to restore a watertight connection between the cartridge filter tank and its lid/upper housing.

This genuine Hayward part (CCX1000G, catalog 4663-30) is manufactured to the original dimensions and material specifications used on select Hayward XStream cartridge filter tanks. Using the correct O-ring helps prevent leaks, maintains proper filter pressure, and ensures the filtration system runs efficiently without loss of suction or water wastage. The O-ring is a small but critical component for proper pool equipment performance and longevity.

What does the Hayward Body O-Ring CCX1000G fit?

The CCX1000G is intended for Hayward XStream cartridge filter tanks that require the specific body-to-lid seal size and profile. It replaces worn, cracked, or flattened rings that no longer compress correctly to form a seal. Installing the proper OEM O-ring avoids improvising with incorrect sizes or materials that can fail prematurely.

• Fits Hayward XStream cartridge filter bodies that list CCX1000G or catalog 4663-30.
• Compatible with original Hayward lid and clamp assemblies for these models.
• Designed to match factory groove dimensions for correct seating.
• OEM material and durometer for long-term compression resistance.

How do I install the replacement O-ring safely?

Installation is straightforward: depressurize the filter, remove the clamp or lid per the manufacturer instructions, extract the old O-ring, clean the groove, and seat the new CCX1000G O-ring evenly. Lightly lubricate with a pool-safe silicone grease to ease seating and reduce the chance of pinching. Reassemble and test under low pressure to confirm a leak-free fit before returning the pool to normal operation.

• Always turn off and depressurize the filter system first.
• Clean the sealing groove of debris and old lubricant before installation.
• Use a non-petroleum, pool-safe silicone lubricant sparingly.
• Check alignment and clamp torque to avoid uneven compression.

What signs indicate the O-ring needs replacement?

Replace the O-ring if you notice persistent leaks at the tank seam, pressure instability, or visible cracking and flattening of the old ring. Even if a ring looks intact, age-related hardening can prevent proper sealing. Regular inspection during routine filter maintenance helps catch seal wear before it causes larger issues.

• Visible cracks, cuts, or hardened surfaces on the O-ring.
• Water seeping from the tank joint under normal pressure.
• Filter pressure that won’t stabilize after normal cleaning cycles.
• O-ring compression set—permanently flattened shape instead of springy recovery.

How does using an OEM O-ring benefit my pool system?

OEM parts like the Hayward CCX1000G are engineered to the original tolerances, reducing the risk of mismatched seals and premature failure. Proper sealing maintains filtration efficiency, prevents water loss, and avoids strain on pumps caused by leaks or air ingress. Investing in the right O-ring helps keep maintenance predictable and extends the life of filter components.

• Exact fit reduces need for adjustments and rework during installation.
• Material compatibility lowers chemical degradation and swelling risks.
• Prevents water and pressure loss for consistent system performance.
• Minimizes downtime and extends the lifespan of filter assemblies.

Who is this for: Pool owners, service technicians, and maintenance professionals who operate or repair Hayward XStream cartridge filters and need an original-equipment replacement seal. If your filter model references part number CCX1000G or catalog 4663-30, this O-ring provides a direct, manufacturer-specified replacement to restore reliable sealing and efficient filtration.
