¾" K55 Brass Stopcock Valve — Inline Water Flow Control

Precision Flow Control — Solid Brass, Built to Last

The ¾" Brass Stopcock Valve is a heavy-duty inline shut-off valve designed to control water flow in domestic and commercial plumbing systems. Machined from solid brass for maximum durability and corrosion resistance, this stopcock features a traditional spindle mechanism that allows precise flow regulation — from fully open to fully closed — with a simple turn of the handle. A trusted staple in plumbing installations across residential, commercial, and industrial settings.

Key Features

• Size: ¾ inch (DN20) — BSP threaded connections on both ends
• Body Material: Solid brass — heavy-duty, corrosion-resistant, and long-lasting
• Operation: Spindle (compression) mechanism — turn handle to open or close flow
• Connection Type: Female BSP threaded inlet and outlet for easy inline installation
• Handle: Integrated brass handle for smooth, controlled operation
• Pressure Rating: Suitable for standard domestic and commercial water supply pressures

How It Works

Install inline on your water supply pipe using the BSP threaded connections. Turn the handle clockwise to close (stop flow) and anti-clockwise to open (allow flow). The compression spindle mechanism provides precise, leak-free control — ideal for isolating sections of pipework for maintenance or repairs.
