PVCu Inch

Effast PVCu inch systems are a high-performance solution for industrial liquid handling applications, offering excellent resistance to a wide range of chemicals. Manufactured from unplasticised polyvinyl chloride (PVCu), these dark grey pipework components are suitable for transporting potable water, diluted acids, alkalis, salts, and water-soluble solvents. With a smooth bore for reduced friction and minimal limescale build-up, Effast PVCu systems are ideal for long-term service with a typical design life of up to 50 years at rated pressure.

• Potable cold water systems
• Food and beverage processing
• Chemical handling and dosing systems
• Water and wastewater treatment
• Swimming pools and spa circuits
• Agricultural irrigation and fertiliser delivery
• General industrial process pipework
• Note: PVCu is not suitable for use with compressed air or aromatic/chlorinated hydrocarbons.

• Size Range: 3/8″ to 8″ (inch series)
• Operating Temperature: 0°C to +60°C
• Pressure Ratings: up to 15 bar, depending on product
• Chemical Resistance: Excellent against diluted acids, alkalis, salts, and water-based solvents
• Standards:
  – Pipes: BS 3505/6, BS EN 1452-2
  – Fittings: BS 4346-1, BS EN 1452-3
  – Threaded components: BS 21, DIN 2999, ISO 7

• Cut the Pipe – Use a plastic pipe saw or wheel cutter for a clean, square cut.
• Chamfer the End – File a 3mm x 45° chamfer to prevent solvent removal during insertion.
• Dry Fit and Mark – Insert the pipe into the fitting and mark the insertion depth.
• Abrade and Clean – Lightly abrade pipe and fitting with emery cloth, then clean with MEK Cleaner.
• Apply Solvent Cement – Use a clean brush to apply cement to both surfaces.
• Assemble Quickly – Push the pipe fully home into the fitting without twisting.
• Hold and Cure – Hold the joint in place briefly, then allow a minimum of 24 hours curing time before pressure testing.
• Pressure Testing – Test the system at 1.5 times the rated pressure.
• Safety Tip: Work in a well-ventilated area and avoid open flames or smoking during installation. Do not use sealing paste.
