Brass SAE 45° Flare Male Ball Check Valve
The Brass SAE 45° Flare Male Ball Check Valve is a compact, in-line one-way valve that allows flow in a single direction and seats to prevent reverse flow. Machined from durable CA360 brass with a SAE 45° male flare inlet and a male NPT pipe outlet, it installs quickly on flared copper, brass, aluminum, or steel tubing in air, hydraulic, refrigeration, and fuel-gas lines.

Typical Applications
Air compressor and pneumatic circuits, hydraulic systems, refrigeration, instrumentation, power steering, and LP / natural gas and flammable-liquid lines where dependable check-valve action and good vibration resistance are required.
Why Choose This Valve
Solid brass construction resists corrosion and vibration for long service life, while the SAE 45° flare connection provides a reliable, reusable metal-to-metal seal. Available in 1/4", 5/16", and 3/8" flare sizes to match common tubing runs, this ball check valve is a low-cost, field-proven way to protect pumps, compressors, and downstream equipment from backflow.
