The JG Speedfit Brass Drain Cock 15 mm is a push‑fit brass valve designed to provide a quick drain‑off point for central heating systems. It’s made from durable DZR brass for corrosion resistance and is compatible with Speedfit PEX, polybutylene and copper pipes (using the proper inserts). You simply push the pipe into the fitting to create a secure connection, and the valve lets you easily drain water from the system for maintenance, repairs or winter shutdowns without complicated tools.
