PVC Pressure Barrell Union

PVC Pressure Barrel Union (Cat 22)

Description:
The PVC Pressure Barrel Union (Cat 22) is designed to allow disassembly of sections of pipework without disturbing the entire system. This makes maintenance, repairs, and modifications easier and more efficient. The union is installed by solvent cementing pressure pipe into each end of the fitting, creating a strong and reliable joint.

Manufactured from high-quality PVC-U (unplasticised polyvinyl chloride), these fittings are rigid, durable, and corrosion resistant. They are suitable for a wide range of pressure applications, including potable water, irrigation, sewerage, and recycled water systems.

Key Features:

• Allows easy disassembly of pipelines without cutting pipe
• Strong, secure solvent cement joint connection (SCJ)
• Manufactured from rigid, high-quality PVC-U
• Suitable for both above-ground and underground use
• Corrosion-resistant, long-lasting, and maintenance-friendly
• White or off-white finish
• Wide range of sizes available (15mm–150mm, larger sizes on request)

Applications:

• Potable water supply
• Pumped sewerage and effluent pipelines
• Irrigation and turf watering
• Pressure sewerage systems
• Slurry and recycled water transport
