PEX has earned its place in the plumbing industry through decades of proven performance. That success, however, can make it easy to overlook materials that have continued to evolve alongside it.

HyperPure® PE-RT tubing from Legend is one of those materials.

HyperPure delivers the performance, pressure ratings, and durability required for today's plumbing applications while introducing additional advantages in workability and sustainability. Those advancements make a strong case for reevaluating PE-RT's role in modern plumbing systems.

Engineered at the Molecular Level

HyperPure starts with advanced bimodal PE-RT resin technology that combines long molecular chains for strength with shorter chains that enhance strength and workability. This engineered structure delivers the durability expected from modern plumbing systems while improving the handling characteristics that set PE-RT apart.

HyperPure meets ASTM F2769 requirements and carries a pressure rating of 200 PSI at 73°F with operating temperatures up to 180°F. The material also delivers a burst pressure rating of 720 PSI at 73°F, exceeding the burst pressure performance commonly associated with comparable PEX systems.

HyperPure combines strength, durability, and workability in a single potable water tubing system backed by a 100-year warranty. Performance credentials like these highlight how far PE-RT technology has advanced and reinforced its position as a serious choice for modern residential and commercial plumbing applications.

Workability Creates Additional Advantages

The same molecular structure that contributes to HyperPure's strength also supports its stay-straight and stress-relaxation characteristics.

With a bend radius 5X the tube's OD, HyperPure maintains alignment more effectively after uncoiling, improving ease of use when routing through walls, ceilings, and mechanical spaces. Instead of fighting coil memory during installation, contractors can focus on completing the system.

Contractors gain these workability advantages without changing the fitting systems and connection methods they already know and trust. HyperPure's workability extends beyond the tubing itself. In addition to supporting most commonly used connection methods, it remains the only flexible potable water tubing capable of fusion joining. That capability gives engineers and contractors greater freedom to select the connection method best suited for the application, rather than the limitations of the tubing.

The Cost of Standing Still

Change can be hard. Adoption of new technologies can be slow. Yet the cost of standing still is not choosing the wrong product. It is overlooking meaningful innovation because habits go unchallenged.

While PEX has staked its claim as the default choice for many plumbing applications, PE-RT has continued to evolve its capabilities. HyperPure showcases how far the technology has advanced, delivering a combination of performance, durability, and workability that challenges long-held assumptions about what PE-RT can achieve.

Rethinking PE-RT is not about abandoning proven solutions. It is about recognizing when material innovation has created something better. HyperPure makes a compelling case that PE-RT has evolved beyond just a viable choice, and into an overall superior solution for modern potable water systems.
