This 1/2 in Male x Male NPT brass check valve stops backflow in a single, compact fitting. The double-male threading connects two female-threaded fittings directly — no extra coupling needed — and the brass body is listed to NSF/ANSI 61 for safe potable water use. Directional markings make correct installation orientation clear, and the internal stainless steel spring keeps the valve responsive. Compact enough for tight spaces, it's built for RV and home water heaters, water pumps, and city water fill connections.
  • ONE-WAY BACKFLOW PROTECTION — Allows water to flow in one direction only, stopping backflow into your freshwater line — directional markings on the body show correct installation orientation.
  • BRASS BODY, NSF/ANSI 61 LISTED — Solid brass construction is listed to NSF/ANSI 61 for safe potable water use, resists corrosion for long-term reliability.
  • DOUBLE MALE 1/2 IN NPT — Male x Male threading connects two female-threaded fittings directly, without needing an extra coupling or adapter in between.
  • VERSATILE APPLICATION — Works for RV and home water heaters, water pumps, and city water fill connections — not limited to a single use case.
  • COMPACT, RELIABLE DESIGN — Small enough to install in tight spaces while the internal stainless steel spring keeps the check valve responsive and consistent.
