Durable Brass Straight Coupler with Nut Size 16x1/2 Ideal for Plumbing

Product Material & Size​

• Premium Brass Construction: Made from high-grade lead-free brass, this coupler resists corrosion, high pressure (up to 16 bar), and temperatures from -20°C to 120°C. Ideal for humid bathroom and kitchen environments, it withstands daily use without rust or deformation.​

• Precise Dimensions: The 16×1/2" size (16mm pipe compatibility with 1/2" threads) fits standard pipes, with a built-in nut for secure tightening. Machine-cut threads on both ends guarantee a tight, leak-proof seal, eliminating the need for extra adapters.​

Use Scenarios​

• Residential Plumbing: Perfect for joining 16mm pipes in home water lines, connecting fixtures like sinks, toilets, or water heaters. Its compact design works in tight spaces, ensuring neat installations under cabinets or in walls.​

• Commercial Spaces: Hotels and restaurants use it to repair or extend plumbing networks, maintaining consistent water flow for multiple fixtures. The nut design allows quick disassembly for maintenance.​

• Light Industrial Settings: Suitable for low-pressure fluid transfer lines in workshops, where reliable pipe connections prevent leaks and ensure operational efficiency.​

How to Use​

1. Preparation: Cut 16mm pipes to the required length, ensuring straight, burr-free ends. Clean pipe threads and coupler ports with a cloth to remove debris for a proper seal.​

2. Installation: Wrap plumber’s tape clockwise around the male threads of one pipe. Insert the pipe into one end of the coupler, then screw the other pipe into the opposing end. Tighten the coupler’s nut with a wrench to secure the connection—avoid over-tightening to protect threads.​

3. Maintenance: Inspect periodically for leaks around the connection. If loose, gently retighten the nut. Clean the coupler with a damp cloth; avoid abrasive cleaners to preserve the brass finish and prevent corrosion.​
