The V&G Compression Stopcock from Evolve is a dependable and easy-to-install valve designed to isolate the water supply in domestic or commercial plumbing systems. Whether you're working on a new installation or replacing an old valve, this stopcock is a practical solution that allows you to shut off the water quickly when needed—for repairs, upgrades, or emergencies. Made from robust brass, this stopcock ensures long-term durability and resistance to corrosion. It comes with compression ends, which means no soldering, flux, or open flame is required. Simply position the stopcock between two pipe sections and tighten the compression nuts using a pair of spanners—fast, secure, and ideal for tight spaces or areas where heat-based work isn't possible. Available in both 15mm and 22mm sizes, the V&G Compression Stopcock fits standard copper pipework and is a trusted choice for plumbers and confident DIYers alike. It’s a key component for gaining control over your water system and adds peace of mind by allowing easy isolation of the supply line.
