PVCu Fittings

Effast PVCu pressure fittings are engineered for dependable use across a wide range of fluid handling applications, including water treatment, chemical processing, and potable water distribution. Manufactured from high-quality unplasticised polyvinyl chloride (PVCu), these inch-size fittings provide excellent chemical resistance, long service life, and compatibility with Effast solvent-weld pipe systems. Available in sizes from ½″ to 8″, Effast PVCu fittings are WRAS and BSI Kitemark approved, ensuring full compliance with UK industry standards.

Note: These fittings are not suitable for use with compressed air.

Installation Overview

  • Cut and Chamfer – Cut the pipe square and chamfer the edge at 30°–40° (approx. 3mm).
  • Dry Fit and Mark – Insert pipe fully into fitting and mark insertion depth.
  • Abrade and Clean – Lightly abrade using an emery cloth the pipe and socket. Degrease both with MEK Cleaner and a lint-free cloth.
  • Apply Cement – Use PVCu cement and apply evenly to both surfaces with a clean brush.
  • Assemble and Hold – Insert pipe fully into fitting. Hold in place for 30–60 seconds, depending on pipe size.
  • Wipe Excess Cement – Remove any cement beads from the joint exterior.
  • Curing Time – Allow 8–24 hours for full cure. Then, pressure test at 1.5x rated pressure.

Threaded Jointing Tips:

  • Tighten by hand; if needed, use a strap wrench for an additional 1/4 turn.
  • Never use pipe wrenches.
  • Do not overtighten — risk of thread or fitting damage.
  • Avoid sealing compounds or pastes that can chemically damage PVCu and ABS.
