Product Features

Hep2O Key System: Built for jobs where tamper resistance and max joint security are critical, such as new builds and social housing. Demounting requires the dedicated HepKey™ tool to release the internal grip ring, preventing accidental joint disturbance. - In4Sure™ Tactile Joint Recognition: Twist the pipe after pushing it in; a distinct tactile 'rumble' confirms the pipe is inserted to full depth for a guaranteed, leak-free connection.
SmartSleeve™ Stainless Steel Support: Captive 316 stainless steel inserts keep the plastic pipe round under high temperatures, lower connection push-in force, and stay locked in the pipe if demounted.
Safer, Flame-Free Fitting: No solder, flux, open flames, or hot works permits needed, making work significantly safer and cleaner in confined areas.
Full 360° Rotatable Joint: Joints rotate freely after assembly without damaging the watertight seal, making pipe alignment simple and stress-free.
Broad System Compatibility: Connects directly to flexible Hep2O polybutylene pipe, standard metric copper pipe conforming to BS EN 1057, or Wavin Tigris press-fit systems via adaptors.
50-Year Guarantee & Approvals: WRAS approved for drinking water and Kitemarked to BS 7291 Class S and BS EN ISO 15876, backed by a 50-year manufacturer guarantee.
UK Manufacturing Heritage: Designed, manufactured and assembled in Doncaster UK.
