PPSU Multilayer Press Fittings

PPSU Multilayer Press Fitting System

Reliable Press Connections for Modern Plumbing

Yinlong's PPSU Multilayer Press Fittings offer a state-of-the-art solution for connecting multilayer composite pipes (like PEX-AL-PEX). This system combines the superior performance of a high-grade PPSU body with the strength of a stainless steel press sleeve, ensuring a fast, secure, and permanent connection without the need for welding, soldering, or glue.

Designed for efficiency and safety, our press fittings feature a "Leak-Before-Press" function and double O-ring seals, providing installers with confidence and peace of mind. They are the ideal choice for hot and cold water supply, as well as heating systems.

Available in both black and white PPSU bodies to suit your project requirements.

Advantages and Specifications

Key Features & Benefits:

  • Press-to-Connect Technology: Rapid and effortless installation using standard press tools, significantly reducing labor time.
  • Leak-Before-Press (LBP) Safety: Un-pressed connections are designed to leak during pressure testing, allowing for easy identification of missed joints.
  • High-Performance Materials: PPSU body is lightweight, corrosion-free, and resistant to scale buildup. The 304 stainless steel sleeve provides a robust and permanent crimp.
  • Double EPDM O-Ring Seal: Two high-quality EPDM O-rings ensure a durable, long-lasting, and watertight seal under various temperature and pressure conditions.
  • Visual Inspection Window: A window on the sleeve allows installers to visually confirm that the pipe has been fully and correctly inserted before pressing.
