Check Valve, Brass, 1-in.

Discover the 1‑inch brass check valve, a robust solution engineered for reliable one‑way flow in plumbing, hydraulic and low‑temperature gas systems. Constructed from heavy‑cast brass, this valve delivers a durable, corrosion‑resistant body that stands up to demanding environments while meeting strict lead‑free regulations.

Why it matters: The design guarantees a positive sealing action across a wide pressure spectrum, from gentle low‑pressure applications to demanding high‑pressure scenarios up to 200 psi. Its dual‑seal system ensures leak‑free performance, protecting your infrastructure and reducing maintenance costs.

• Heavy‑cast brass construction: Provides exceptional strength for cold‑water, oil or gas service while resisting corrosion and wear.
• Stainless‑steel core with Buna‑N lining: Offers a resilient moving part that maintains smooth operation and resists chemical attack.
• Integrated molded cross: Prevents accidental shut‑off from over‑tightening, extending valve lifespan.
• Dual O‑ring poppet design: Two molded O‑rings stay securely in place, delivering a reliable seal that cannot be displaced.
• Progressive sealing action: The top O‑ring seals at low pressure, while both O‑rings engage at higher pressures for enhanced leak protection.

Bottom line: This 1‑inch brass check valve combines sturdy materials, smart engineering and compliance with lead‑free standards to deliver consistent, leak‑free flow control. Ideal for residential, commercial and industrial installations, it ensures peace of mind and long‑term reliability wherever precise fluid direction is required.
