PEX History and Advantages

Cross-linked polyethylene, known as PEX, was developed about 50 years ago and is utilized today in many applications, including tubing and pipes/piping material used in the plumbing industry.

The properties of PEX make it stable, yet flexible, through a wide range of temperatures and pressures, allowing for high impact strength, abrasion resistance, and crack resistance when used in plumbing applications.

PEX pipes pair with a wide range of plumbing connections and fixtures to ensure all water distribution needs are met. The PEX system fittings are mechanical which makes installation quick and easy, ultimately reducing labor time and costs. PEX is changing and simplifying the plumbing installation landscape and our Water Armor® PEX fittings are helping to make that happen. Learn more about the best uses for PEX fittings here.

Whether you’re repairing a kitchen faucet, installing a high capacity commercial system, or supplying hundreds of contractors, we produce the highest quality, American-made parts. Residential plumbers, commercial plumbing pros, and distributors trust us for products that are not only compatible with demanding installations but also comply with stringent industry standards.

By choosing American-made, you’re not only supporting domestic manufacturing but you’re also getting faster delivery, consistent inventory, and a direct line to knowledgeable customer support.

Our plumbing parts, fittings, and components are precision-machined with ECO BRASS® C69300, a lead-free* alloy that is engineered for superior corrosion resistance and reduced mineral buildup—critical for maintaining water quality and system longevity.

In addition, the compatibility with PEX tubing offers flexibility for both residential and commercial installations.

Whether it’s a custom home build, a large multi-family complex, or a single repair call, we provide fittings and connectors that ensure leak-free performance. They are also compatible with PEX A, PEX B, PEX C, and copper, which gives plumbers the flexibility they need for any home project, from kitchen and bath remodels to full plumbing system upgrades.
