Why Cambridge Brass Leads Municipal Water Infrastructure

Pioneer in Lead-Free Technology

Cambridge Brass was among the first manufacturers to adopt no-lead brass production for waterworks, exceeding regulatory requirements before they became mandatory. Our commitment to public health protection makes us the trusted choice for safe drinking water systems.

Complete Municipal Product Ecosystem

Unlike specialized manufacturers, Cambridge offers a comprehensive portfolio of compression fittings, curb stops, corporation stops, service line fittings, and meter valves. This complete system ensures compatibility and consistency across your entire water infrastructure.

Precision Engineering for Zero Leaks

Our brass fittings maintain tight tolerances through precision machining, delivering leak-free performance that municipal systems depend on. Every waterworks project relies on this level of precision, and Cambridge Brass delivers consistency you can trust.

Certified Quality Standards

All Cambridge fittings meet or exceed AWWA C800, NSF/ANSI 61 & 372, and CSA B137.1 certification standards. These rigorous certifications reduce risk for municipal buyers who must comply with regulatory requirements.

Frequently Asked Questions

What makes Cambridge Brass fittings ideal for water service lines?

This adapter features lead-free brass construction and a pressure rating of 300 PSI, making it safe and strong for potable water applications. It connects CTS copper or HDPE tubing to threaded plumbing systems, like a male pipe thread adapter, while meeting AWWA C800 and NSF/ANSI 61 & 372 standards for compliance and performance.

What are the key installation tips for Cambridge Brass compression fittings on HDPE lines?

When using Cambridge Brass compression fittings on HDPE pipes, always use a stainless steel stiffener to support the pipe internally. Mark the pipe for alignment and ensure even gasket compression by tightening the H nut fully to achieve a leak-free, pull-out-resistant joint. This applies to both CTS and IPS stiffeners.

Are Cambridge Brass fittings interchangeable with IPS-sized piping systems?

No, our Cambridge fittings for CTS (Copper Tube Size) match the pipe’s outside diameter and are not interchangeable with IPS (Iron Pipe Size) fittings. Using mismatched sizes, such as trying to connect a CTS compression curb stop valve to an IPS pipe, could lead to installation issues or leaks. We offer distinct products for both systems, including IPS curb stops and IPS main stops.

Can I use these fittings in freezing climates?

Yes. Cambridge Brass Canada products are built for Canadian conditions. They are commonly installed below frost lines to ensure reliable performance even in the coldest temperatures, making them a top choice for municipal projects across North America.

Why is lead-free brass important in Cambridge Brass water fittings?

Lead-free brass ensures our fittings, like the AWWA main stop, meet NSF/ANSI 61 & 372 standards for safe potable water. This protects public health by eliminating lead contamination risks, a critical factor for modern water safety regulations. It's a standard you can expect, whether you're using a CTS or an IPS adapter.
