Fast

PLASSON Series One offers push fit connections for PE water pipe up to 63mm. The fittings deliver the same reliability and pull-out resistance as conventional compression fittings, with the added advantage of being installed in half the time.

Smart

Series One fittings feature an innovative self-centering grip ring that ensures perfect alignment between the pipe and fitting—delivering a secure, leak-free seal and making installation more reliable and efficient.

Reliable

Series One fittings feature captive O-rings that create a watertight seal the moment the fitting is placed on the pipe—ensuring fast, secure connections with no need for adjustments. Rated to withstand pressure up to 16 bar and backed by a 50-year guarantee offering long-term reliability and peace of mind.

Secure

Series One fittings include tamper-proof nuts designed to deliver secure, vandal-resistant connections—making them ideal for public settings such as parks, golf courses, and other high-traffic areas where durability and safety is essential.

Reusable

The tamper-proof nuts can be released using a special wrench so fittings can be easily repositioned or reused. This makes Series One ideal for temporary installs on building sites, farms or in agricultural settings.
