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

Meet the B&K ProLine 1/2 in Comp x Comp Brass Gate Valve—a durable, reliable shutoff designed for residential water lines and light commercial duties. Crafted from solid brass and finished to stand up to everyday use, this valve delivers steady, leak-free performance where you need to control flow precisely.

  • Brass construction offers superior strength, corrosion resistance, and long-term durability in potable water applications.
  • Lead-free design ensures safety and compliance for drinking water systems.
  • 1/2 in compression x compression (Comp x Comp) connections simplify installation on copper or compatible tubing, creating a secure, leak-tight seal without complex threading.
  • 200 psi maximum pressure provides confidence for typical household and light-commercial water lines, accommodating standard supply pressures.
  • Bagged packaging protects the valve during transit and on-shelf presentation, making it a dependable choice for pro installers and DIY projects alike.
  • Gate valve design delivers reliable on/off control with a minimal footprint, ideal for shutoff points in plumbing runs.

Who should consider the B&K ProLine 1/2 in Comp x Comp Brass Gate Valve? Homeowners upgrading a bathroom, laundry, or kitchen supply line; plumbers stocking a trustworthy, lead-free valve for cold-water circuits; and contractors working on irrigation or utility-provided water services where a compact, dependable shutoff is needed.

Practical use cases include:

  • Replacing a failed shutoff on a copper supply line in a bathroom or kitchen
  • Isolating a section of outdoor irrigation or garden hose supply for maintenance
  • Installing a reliable, lead-free valve at a utility manifold or base plumbing run

Installation tips to get the best performance:

  • Ensure clean, deburred tubing ends before attaching compression fittings
  • Tighten connections securely using standard hand-tight plus a wrench for a snug seal (avoid over-tightening)
  • Confirm the valve is fully closed or open before applying pressure to the line
