Restore Strong, Consistent Suction to Your Barracuda Pool Cleaner

If your suction-side pool cleaner has slowed down, stopped climbing walls, or lost its rhythmic pulsing motion, a worn diaphragm is often the cause. The Zodiac Barracuda Duralife Diaphragm is a genuine OEM replacement diaphragm designed to restore proper suction, movement, and cleaning performance in compatible Zodiac Barracuda pool cleaners.

This diaphragm is the core moving component that drives the cleaner. Replacing it at the right time prevents strain on your pump system and keeps the cleaner operating as designed.

Genuine Duralife Construction for Extended Service Life

Zodiac’s Duralife diaphragm is engineered from a proprietary flexible polymer designed to withstand constant flexing, debris impact, and chemical exposure. Compared to standard diaphragms, the Duralife version offers improved durability and a longer replacement interval under normal operating conditions.

Using an OEM diaphragm ensures correct thickness, flexibility, and valve action—critical for maintaining proper suction pulses.

Why the Diaphragm Is Critical to Cleaner Performance

Suction-side cleaners rely entirely on the diaphragm’s movement to create forward motion and debris intake.

Why it matters:

• Restores proper suction and cleaner movement

• Improves wall climbing and coverage

• Prevents stalling and short cycling

• Reduces unnecessary load on the pool pump

Designed for Zodiac Barracuda Suction Cleaners

The Zodiac Barracuda Duralife Diaphragm is compatible with several popular suction-side cleaner models, including:

• Barracuda G2

• Barracuda G3

• Ranger

• Wahoo

• T3

• T5

Always confirm your cleaner model before ordering to ensure correct compatibility.

Ideal for Preventive Maintenance

The diaphragm is a routine wear item and should be inspected periodically, especially if the cleaner is used daily or in pools with heavy debris. Replacing the diaphragm early helps avoid poor cleaning performance and prevents secondary wear on the cleaner body and hoses.

Many service professionals replace the diaphragm annually as part of scheduled maintenance.

Installation Notes

Turn off the pool pump before servicing. Remove the cleaner from the pool, open the diaphragm chamber, and replace the old diaphragm with the new Duralife diaphragm according to manufacturer instructions. Ensure proper seating and alignment before reassembly. No special tools are required, and installation typically takes only a few minutes.
