Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the B&K ProLine 1/2 in. CTS to 1/2 in. CTS Brass Coupling—the durable, lead-free connector designed for reliable copper tubing joins in potable water systems. Crafted in solid brass, this ProLine fitting delivers consistent performance in tight spaces, making it a trusted choice for repairs, renovations, and new-install projects where 1/2" CTS pipes need a precise, corrosion-resistant link.

Why this 1/2" CTS brass coupling stands out

  • Lead-free brass construction provides safer drinking water and aligns with common residential codes, reducing worries about metal migration into supply lines.
  • Two 1/2" CTS ends engineered for standard Copper Tube Size piping, ensuring a compatible, straightforward installation with typical copper tubing systems.
  • 125 psi maximum pressure and 210°F maximum temperature coverage fit everyday hot and cold water service as well as many heating and appliance connections.
  • ProLine durability from B&K, a brand known for dependable fittings that hold up to routine maintenance and busy installation environments.
  • Not ANSI certified (as labeled) — a practical, non-ANSI option for projects where such certification isn’t required.

Ideal use cases

This coupling is perfect for extending or repairing 1/2" CTS copper runs in kitchens, bathrooms, laundry areas, and utility rooms. Use it wherever you need a straightforward, robust connection between two 1/2" CTS copper tubes—whether you’re replacing a leaky section, adding a fixture, or re-routing a short supply line.

Practical guidance for installers

  • Verify that both pipe ends are clean and undamaged before assembly to promote a leak-free joint.
  • Handle the fitting with care in tight spaces; brass bodies resist daily wear when properly installed.
  • Follow local codes for potable water fittings and ensure the chosen installation method aligns with system requirements.
