Boshart - PEX Fittings

Boshart PEX Fittings: Built for Performance

Boshart offers high-performance PEX fittings designed for durability, flow efficiency, and ease of installation in both residential and commercial plumbing systems. Known for their stainless steel construction and innovative sweep elbow design, these fittings include cold expansion options compatible with PEX-A tubing. This method uses the pipe's natural "memory" to create a secure, leak-proof seal without compressing the pipe wall. Cold expansion fittings improve flow by preserving the pipe’s internal diameter, reduce connection failures, and are ideal for tight spaces due to the flexibility of PEX-A. Though requiring specialized tools, they outperform crimp systems in reliability and performance, particularly in areas with corrosive water or strict flow requirements.

Why Choose Boshart - PEX Fittings?

Boshart PEX fittings, known for their durability and precision, are engineered to deliver long-term performance in residential and commercial plumbing systems. Made from high-quality materials like lead-free brass and poly-alloy, these fittings offer excellent corrosion resistance and comply with industry standards for safety and reliability. Boshart's line of cold expansion fittings is specifically designed for use with PEX-A tubing, which allows the pipe to expand and then contract to form a strong, leak-proof connection without the need for clamps or crimp rings. These PEX fittings are available at our Canadian warehouse. Check them out below:

Stainless Steel Cold Expansion PEX x MPT Adapter

The Stainless Steel Cold Expansion PEX x MPT Adapter are a durable, corrosion-resistant solution for both hot and cold water PEX piping systems. Made from high-quality 304 stainless steel, they are ideal for harsh water conditions and areas with high acidity. Engineered for ASTM F1960 PEX systems using the cold expansion method, these fittings ensure secure, leak-free connections and allow for maximum water flow thanks to their large internal diameter. They are compatible with SDR9 PEX tubing and various standards, including ASTM F2769, F876, and F3253.

Stainless Steel Cold Expansion PEX x FPT Adapter

The Stainless Steel Cold Expansion PEX x FPT Adapter features a large internal diameter for maximum flow and compatibility with ASTM F1960 PEX systems. It supports both hot and cold water applications. Utilizing cold expansion technology, it ensures tight, reliable seals and is certified lead-free for potable water use. Rated for up to 400°F and 200 PSI, it meets multiple industry standards, including NSF/ANSI 372 and 61.

304 Stainless Steel Cold Expansion PEX Ball Valve

The 304 Stainless Steel Cold Expansion PEX Ball Valve is a durable, corrosion-resistant solution for both potable and non-potable water systems. Rated for 600 PSI CWP and compatible with ASTM-certified PEX and PE-RT tubing, it features a full-port design, cold expansion PEX ends (ASTM F1960), and a blow-out proof stem for reliable, leak-free performance. Operating in temperatures from -40°F to 200°F, it’s ideal for demanding environments and harsh water conditions.

FAQs

1. What makes cold expansion PEX fittings different from crimp or clamp styles?

Cold expansion PEX fittings use the pipe's elasticity to form a seal. The PEX-A pipe is expanded with a tool, and a larger-diameter fitting is inserted. As the pipe contracts, it forms a tight, secure seal without needing metal crimp rings or clamps.

2. Why are cold expansion fittings only used with PEX-A tubing?

Only PEX-A tubing has the flexibility and shape memory needed to expand and then contract around the fitting securely. PEX-B and PEX-C are stiffer and don’t recover well enough to maintain a reliable seal in cold expansion applications.

3. Are cold expansion PEX fittings more resistant to leaks over time?

Yes, they provide a highly reliable connection due to the compression seal created by the pipe contracting around the fitting. There are no external clamps that can loosen, making these fittings particularly durable over long periods.

4. Can cold expansion fittings handle frequent temperature fluctuations in plumbing systems?

Absolutely. The flexibility and memory of PEX-A combined with the design of cold expansion fittings allow them to absorb expansion and contraction caused by temperature changes, making them ideal for both hot and cold water lines.

5. Can cold expansion fittings be used for underground water lines?

Yes, when using approved PEX-A tubing and fittings rated for direct burial, cold expansion systems can be used underground. However, it's essential to follow local codes and ensure proper backfill to protect the pipe and fitting.
