Hydrosert® Coupling – Quick-Install Fittings for PE Pipe

The Hydrosert® mechanical coupling from Elster Perfection is designed for fast, secure joining of polyethylene (PE) piping without the need for fusion equipment or special training. Its industry-leading "no-stress" design separates the gripping and sealing areas, ensuring reliable, leak-free performance in gas utility and industrial applications.

Built from non-corrosive, high-strength materials, Hydrosert® fittings install in minutes and offer full restraint—making them the preferred choice for efficient PE pipe installations with long-term durability.

Key Benefits

Hydrosert® couplings deliver field-proven performance with reduced labor, equipment, and installation time:

• No special tools, fusion equipment, or generators required
• Installs in under a minute with one person
• Compatible with a wide range of PE pipe sizes
• Lead-free and compliant with AWWA C901 and NSF Standard 61
• Reduces trench size and jobsite disruption
   

Features

Every Hydrosert® fitting is engineered to support consistent, stress-free installation and long-term reliability:

• Molded from HDPE (PE3408/PE4710) for maximum strength
• One-piece construction – no loose components
• Independent gripping collet and elastomeric seal system
• Allows pipe rotation without breaking seal
• Available in CTS and IPS sizes (¾" to 2")
• Pressure-rated up to 200 PSIG
   

Benefits

Compared to electrofusion and heat fusion methods, Hydrosert® offers significant time and cost savings:

• Total installed cost is lower due to reduced labor and equipment
• Excellent performance in all weather conditions
• Non-corrosive design eliminates need for special coatings
• Pull-out strength exceeds that of the connected PE piping
• Simplifies training and speeds up field operations
   

Capability

Hydrosert® mechanical couplings are ideal for utility, gas distribution, and underground PE piping systems:

• Used in residential, commercial, and industrial gas service
• Supports both new installations and emergency repairs
• Compatible with SDR 9 and SDR 11 pipe in CTS and IPS sizes
• Available in multiple configurations and lengths
