Zodiac / Baracuda W70345 Cassette Chamber Assembly with Compression Ring (G3 / G3 Pro)

The Zodiac Baracuda W70345 is an OEM replacement cassette chamber assembly that includes the compression ring for compatible Baracuda suction-side pool cleaners. This chamber supports the cleaner’s diaphragm cassette and helps maintain a tight, stable seal so suction is applied efficiently for consistent cleaner movement.

Key Details

  • Brand: Zodiac / Baracuda
  • Part Number: W70345
  • Part Type: Cassette chamber assembly with compression ring
  • Function: Holds the cassette/diaphragm assembly and provides sealing/compression for proper suction operation
  • Common Replaces: W69559, W69563, W70334

Compatible Cleaners (Common Applications)

  • Zodiac Baracuda G3
  • Zodiac Baracuda G3 Pro

What This Part Does

  • Provides the chamber and clamp/compression interface that secures the cassette/diaphragm assembly.
  • Helps prevent suction loss caused by a cracked, warped, or loose cassette chamber.
  • Supports smooth cleaner travel by keeping the diaphragm assembly properly seated and aligned.

When to Replace

  • Cracks, splits, or warping in the chamber body
  • Compression ring no longer clamps securely or pops loose
  • Persistent suction loss, stalling, or erratic movement after diaphragm service
  • Repeated leaks/air intrusion at the cassette area

Installation Notes

  • Turn the pump off before servicing the cleaner.
  • Remove the cassette assembly, swap the chamber as needed, and reinstall the cassette so it seats evenly.
  • Ensure the compression ring is fully seated and locked to prevent bypass/leaks.
  • After reassembly, restart the pump and confirm the cleaner moves steadily without slipping or stalling.

Maintenance Tip

If you’re servicing the cassette area, inspect the diaphragm for tears and confirm the cassette chamber surfaces are clean and free of grit before locking the compression ring. A small piece of debris at the seal can cause suction bypass and poor cleaner movement.
