Brass Three-Way Valve Body Fitting

As a critical connection node in fluid control circuits, this brass three-way fitting combines external and internal threads to efficiently split or merge media flow. The body is machined from solid bar stock in a single CNC turning operation, ensuring perpendicularity and concentricity between thread axes. It is ideal for hydraulic, pneumatic, and water treatment systems requiring high sealing performance.

The square milled flats on the side provide wrench engagement points for secure tightening and serve as key secondary clamping references during machining, effectively preventing slippage or deformation risks associated with cylindrical clamping. The internal threads on the top and sides are precision-tapped with full, smooth profiles, while the multi-step external threads at the bottom accommodate various standard hose fittings or hard tube nuts, ensuring reliable air and water tightness after assembly.

Leveraging our Ningbo factory's mature cluster of CNC turning and machining centers, we offer high-precision batch manufacturing for such multi-feature rotational parts. Dimensions are controlled throughout the entire process, from raw bar cutting to final thread rolling or cutting. Buyers can provide detailed drawings to specify thread standards (e.g., NPT, BSP, or M series) and tolerance grades. We will evaluate the optimal machining process and surface treatment based on specific application scenarios to ensure delivered products meet stringent industrial standards.
