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.

Built for Professionals Who Demand the Best

Residential plumbers.
Commercial contractors.
Plumbing distributors and suppliers.

If you work in the industry, we work for you.

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.

Why Buy American Made Plumbing Products

Choosing us means choosing reduced callbacks, longer-lasting results, and the confidence to get the job done right the first time. Every product we sell is proudly manufactured in the USA, ensuring strict quality control, consistent tolerances, and reliable performance on every job. 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. The antimicrobial properties of ECO BRASS® protect against bacterial growth and all parts exceed ASTM and ANSI standards. In addition, the compatibility with PEX tubing offers flexibility for both residential and commercial installations.

Performance and Compliance for Every Industry

Residential Plumbing

The Brass Warehouse components are designed to reduce callbacks. 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.

Commercial Plumbing

Commercial plumbing requires components that can perform under continuous use, variable pressures, and strict health and safety regulations. We serve a wide range of commercial markets, including:

Restaurants & Food Service – Components that meet NSF standards for potable water and resist the harsh conditions of commercial kitchens, including high heat, cleaning chemicals, and grease, are fundamental to the fast-paced food industry.
Hospitality – Reliable fittings and connectors in hotel, resort, and conference center plumbing systems must be able to handle high occupancy without service interruptions.
Healthcare Facilities – Antimicrobial ECO BRASS® components are ideal for hospitals, clinics, and long-term care facilities where infection control protocols and water quality is essential to patient care.
Educational Institutions – Durable, code-compliant products for schools and universities must be able to withstand daily, high volume operation and decades of use.
Government & Municipal Buildings – Products that meet ‘Buy American’ and other procurement requirements ensure compliance for public works and infrastructure projects.
Industrial Operations – High-strength, corrosion-resistant solutions are vital for factories, processing plants, and manufacturing facilities where downtime is costly and reliability is non-negotiable.
