CNC Machined Carbon Steel Valve Body Connector with High Durability for Pneumatic Valve Fittings

CNC Machined Carbon Steel Valve Body Connector is an essential precision fitting for industrial pneumatic control systems. Made of high-quality carbon steel, the product adopts cold heading forming to strengthen the internal metal structure, followed by professional CNC turning and milling finishing.

With strict dimensional tolerance, compact structure, excellent pressure resistance and reliable sealing performance, this valve connector is widely used for valve body connection, air circuit transition and pipeline sealing. It works stably under frequent opening and closing, constant air pressure and dynamic impact conditions, perfectly matching air compressors, solenoid valves, pressure regulating valves and various fluid control equipment.

Both standard stock supply and custom OEM processing are available.

Adopting industrial-grade carbon steel material, the connector features uniform internal structure, high hardness and good toughness. It provides excellent compression resistance, deformation resistance and impact resistance, maintaining stable performance under long-term pneumatic load.

Multiple surface treatments such as black oxide, zinc plating, nickel plating and Dacromet coating are optional for anti-rust and anti-corrosion purposes, suitable for various indoor industrial working environments.

The combined manufacturing process ensures both high mechanical performance and high dimensional accuracy. Cold heading densifies the steel structure to enhance strength and fatigue resistance, while CNC precision machining strictly controls bore size, thread standard, concentricity and flatness.

All parts are burr-free with smooth and standard threads. Uniform assembly clearance effectively prevents air leakage, pressure loss and loosening, ensuring stable sealing and consistent batch quality with excellent interchangeability.

This valve body connector is universally compatible with mainstream pneumatic components, including solenoid valves, pressure control valves, pneumatic stop valves and air compressor valves. It is widely used for valve body docking, air path conversion and pipeline sealing.

Easy to install and disassemble, it serves as a standard fitting for automated pneumatic circuits and fluid control systems.

We support full customization according to customer drawings and samples, including custom bore diameter, length, thread specification, steps, grooves and special-shaped structures. Various surface finishing options are available.

Orders from prototype trial production to large-scale mass production are acceptable to meet personalized precision connection requirements for non-standard pneumatic and fluid equipment.
