PPSU Quick and Easy Fittings

PPSU Quick and Easy Fittings System

The Future of Pipe Connection is Here

Yinlong's PPSU Quick & Easy (Q&E) fitting system represents the pinnacle of plumbing technology, designed for use with PE-Xa pipes. This innovative cold expansion method creates a secure, long-lasting, and full-flow connection in seconds. By leveraging the thermal memory of PE-Xa pipe, our Q&E system ensures a permanently tight seal that actually strengthens over time, providing unparalleled reliability for both residential and commercial projects.

Made from high-performance Polyphenylsulfone (PPSU), our fittings offer superior resistance to high temperatures, pressure, and aggressive water conditions, making them a safe and durable alternative to traditional metal fittings.
