Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Keeney 1/2 in. FPT inlet to 3/8 in. Brass Shut-Off Valve is built to deliver precise, dependable control right at the point where you need to stop or regulate water flow. With a chrome finish over a solid brass body, this valve blends durability with a clean, polished look that fits beneath sinks, behind appliances, or along any standard residential water supply line.

Key features and why they matter:

  • Inlet/outlet details: 1/2 in. FPT inlet and a 3/8 in. connection on the outlet side, providing a compact, versatile option for common supply line configurations.
  • Material you can trust: Solid brass construction offers long-lasting performance in wet environments, resisting corrosion and wear over time.
  • Chrome finish: A durable, easy-to-clean surface that maintains its shine while resisting tarnish in everyday use.
  • Convenient operation: Quarter-turn handle, designed for quick, precise shut-off with a single, smooth motion. The oval handle is comfortable to grip and easy to turn, even in cramped spaces.
  • Safety and water quality: Lead content less than 0.25% aligns with common lead-free standards, making it suitable for drinking-water-related applications and home installations.
  • Practical packaging: Boxed for safe transport and ready for installation; includes 1 valve per package, ideal for single-use repairs or standard home upgrades.
  • Designed for water supply: Specifically engineered to regulate flow in residential water systems, from faucets and dishwashers to ice-makers and other supply lines.

Use cases and installation ideas:

  • Under-sink faucet installations where a reliable shut-off is needed without adding extra bulk to the space.
  • Supplying ice makers, dishwashers, or other appliances that benefit from a dedicated shut-off valve close to the line.
  • Retrofits in older homes where a compact 1/2 in. FPT inlet to 3/8 in. outlet matches existing pipe work without extensive re-plumbing.

Practical tips for a solid install:

  • Before threading, ensure the male threads are clean and free of debris to avoid cross-threading and leaks.
  • Use an appropriate thread sealant or Teflon tape on male threads to promote a tight seal, then snugly tighten with a wrench—avoid overtightening to protect the valve seals.
  • Check for leaks after initial operation; cycle the valve a few times to verify a smooth shut-off and steady flow when opened.

This valve stands out by delivering reliable brass construction, a chrome aesthetic that fits with modern fixtures, and a precise quarter-turn action—making everyday shut-offs quick, clean, and predictable. If you’re updating a water-supply point or completing a focused replacement with a 1/2 in. FPT inlet and 3/8 in. connection, this Keeney shut-off valve is a thoughtful, capable choice that prioritizes performance and practicality in one compact package.
