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.

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
