Across Canada, many municipalities still rely on traditional copper service lines or early-generation plastic piping for their water service connections. While these legacy systems have served communities for decades, they come with limitations: 
corrosion, costly repairs, reduced flow over time, and energy inefficiencies. As infrastructure ages and municipalities face increasing pressure to modernize, the need for a smarter, long-term solution has never been clearer.
Enter LYNX-PEX™ — the Next Evolution in Municipal Water Service Tubing
Proudly made in Canada by CB Supplies Ltd., LYNX-PEX is constructed from durable PEX-b material, known for its strength, flexibility, and long-term performance. Designed to meet and exceed ANSI/AWWA C904, ASTM F876, and CSA B137.5 requirements, 
LYNX-PEX boasts the industry’s highest chlorine and UV resistance ratings for PEX tubing. It’s also certified to NSF/ANSI/CAN 61 and NSF/ANSI 14, meeting the most stringent standards for drinking water systems. Backed by a worry-free 25-year warranty, it’s built for peace of mind and long-term reliability.
Unlike copper, which can corrode or accumulate mineral buildup over time, LYNX-PEX offers superior corrosion resistance, ensuring clean, high-quality water for decades. Its smoother inner wall surface delivers maximum long-term flow rates, reducing the energy needed for pumping and improving overall system efficiency.
Installation is another area where LYNX-PEX stands out. It’s lightweight, flexible, and doesn’t require special tools, cutting down on installation time and labour costs. With the industry’s maximum UV resistance rating available, and maximum chlorine resistance ratings for PEX, municipalities can be confident they’re installing a product built to withstand Canada’s diverse environmental conditions.

LYNX-PEX with Tracer Wire – Built-In Detectability for Added Peace of Mind
For applications where future location and detection are critical, LYNX-PEX Water Service Tubing with Tracer Wire offers a smart, high-performance solution. Manufactured with integrated 14-gauge (AWG) white tracer wire, this tubing allows for quick and accurate detection after installation—minimizing the risk of accidental damage during future excavation or construction work.
Available in ¾”, 1″, 1¼” & 1½” CTS OD SDR-9 sizes, with standard coil lengths of 60 ft., 75 ft., and 100 ft., this variant maintains the same durable, corrosion-resistant PEX-b construction as standard LYNX-PEX. Custom coil lengths, wire gauge and colour of sheathing for wire gauge are also available upon request, providing added flexibility for project-specific needs.
In a time when infrastructure spending needs to be both strategic and future-focused, LYNX-PEX gives municipalities a dependable, Canadian-made solution that improves performance today and delivers long-term value.
Nothing LYNX better!
