Use cases you’ll appreciate: replacing a worn-out supply valve under the sink, linking a 5/8 in. supply line to a 3/8 in. flex line for faucet or ice-maker connections, or upgrading aging hardware where a compact, straight valve fits the available space. The straight design fits tight crawl spaces and cabinetry where angle valves don’t reach, while the durable brass body and chrome finish stand up to daily use and moisture exposure.
Why this valve stands out: it combines reliable compression connections with a dependable, lead-free brass core and a finish designed for longevity. The result is a leak-resistant shutoff that installs without soldering, streamlines maintenance, and keeps your water flow precisely where you need it. This is an authentic Keeney solution crafted for plumbers, contractors, and discerning homeowners who value performance, safety, and a tidy, professional install.
Quick installation tips: ensure the supply line ends are clean and deburred, slide on the compression nuts and ferrules, then tighten securely with a wrench. After installation, slowly turn the water back on and check for leaks at both compression joints.
