What this valve does and why you need it 1/2" NPT female x female brass ball valve provides reliable shutoff and full flow for water, oil, gas, compressed air and irrigation systems. The full-port design keeps flow unrestricted and reduces pressure drop compared with reduced-bore valves, so pumps and compressors work more efficiently and lines remain balanced. Key benefits Durable construction: solid brass body resists corrosion and wear for long service life in industrial and residential installations. Secure handling: stainless steel handle with a plastic-coated grip gives a firm, comfortable hold and resists bending or corrosion. Smooth operation: engineered for easy, reliable opening and closing with minimal effort. Wide compatibility: 1/2" NPT female x female threads fit standard 1/2" NPT male fittings and pipe, compatible with common plumbing and pneumatic systems. What makes it stand out Full-port bore minimizes pressure loss and prevents restrictions that can reduce system performance. Robust material choices (brass body, stainless-steel handle core, plastic coating on the grip) balance durability and user comfort without adding maintenance complexity. Typical applications / use scenarios Irrigation shutoff: use between a water supply line and irrigation manifolds to isolate zones for maintenance without significant pressure loss. Workshop compressed air: install as an inline shutoff for air lines to isolate tools or equipment quickly and reliably. Utility and fuel lines: suitable for residential and light industrial water, oil or gas lines where a compact, full-flow shutoff is needed. Quick specifications and installation notes Size: 1/2" NPT female x 1/2" NPT female Body material: brass Handle: stainless steel core with plastic-coated grip Design: full port (full bore) for reduced pressure drop Compatible media: water, oil, gas, compressed air, irrigation Installation: connects to standard 1/2" NPT male threads; thread sealing (e.g., PTFE tape) recommended per local codes and practices. This valve is intended as a compact, reliable inline shutoff that preserves system flow while providing a comfortable, durable operating handle for frequent use.
