Hayward ECX1031 Replacement 13-3/8-Inch Flex Tube Assembly for EC65 Perflex Filters — 5-Pack, OEM Fit

Hayward ECX1031 is a direct replacement 13-3/8-inch flex tube assembly sold in a convenient 5-pack for EC65 Perflex pool filters.

If you maintain a Hayward Perflex extended-cycle filter system, worn or cracked flex tubes reduce filtration efficiency and can lead to cloudy water or increased pump strain. The ECX1031 flex tube assemblies restore the internal flow channels of EC65 (and compatible Perflex models), letting your filter operate closer to factory performance. Each pack contains five identical tubes so you can replace multiple damaged units in one service session.

Will these flex tubes fit my Hayward EC65 Perflex filter?

Yes — these flex tubes are sized specifically for the EC65 Perflex model and match the OEM dimensions. The length is 13-3/8 inches and the connection ends align with the Perflex tube stack design. They are engineered to work with the EC65's manifold and spacer system.

• Exact length: 13-3/8 inches to match original components
• Designed for Perflex extended-cycle filters including EC65
• Compatible with standard Perflex tube-stack fittings and spacers

How do these replacement tubes improve filter performance?

Replacing damaged or brittle flex tubes restores consistent water flow through the internal assembly, reducing bypass and trapping more debris in the filter pack. Proper tubes preserve the designed hydraulic balance so the system operates at intended turnover and pressure. Fresh tubes also help extend the life of other filter internals by preventing uneven wear.

• Re-establishes correct internal flow paths for optimal filtration
• Prevents water channeling around damaged tubes
• Reduces strain on the pump caused by inefficient filtration

What should I know about installation and maintenance?

Installation is a straightforward maintenance task for anyone familiar with Perflex disassembly; it commonly requires removing the filter head and swapping the old tubes for new ones. Inspect adjacent parts like O-rings, spacers, and manifolds while the unit is open and replace any worn pieces. Reassemble carefully and test for leaks and proper pressure before returning the filter to regular service.

• Typical service: remove head, swap tubes, reassemble
• Check O-rings and spacers; replace if hardened or cracked
• Run short pressure test after reassembly to confirm sealing

How many tubes come in a pack and why buy the 5-pack?

This listing includes five identical ECX1031 flex tube assemblies, which is convenient if multiple tubes in your stack are aged or if you perform scheduled maintenance across several filters. Buying a 5-pack reduces downtime and ensures you have matching parts on hand for staggered servicing. It also often provides better value than purchasing single tubes one at a time.

• Pack quantity: 5 matching flex tube assemblies
• Good for multi-tube replacements or future maintenance needs
• Simplifies inventory for pool service professionals and owners

Who is this for: Pool owners, maintenance technicians, and service shops using Hayward Perflex extended-cycle filters (especially EC65) who need an exact-length, OEM-compatible flex tube replacement. Choose this 5-pack if you want to restore proper filtration quickly, keep spare parts on hand, or service multiple filters efficiently.
