Industrial-grade brass fittings engineered for zero-leak performance and extreme durability.
With over 15-20 years of vertical integration in pneumatic machinery, NHPC (Nuoheng Pneumatic Machinery Co., Ltd.) embodies Expertise, Authoritativeness, and Trustworthiness. Our engineers specialize in high-precision metallurgy and leak-proof design.
Leveraging advanced CNC lathes, injection molding, and die-casting, we provide the ultimate ODM/OEM brass connector pipeline solutions. Every fitting undergoes 100% pressure testing to ensure industrial safety.
Operating from China’s manufacturing heartland, we offer unmatched supply chain resilience. We serve global markets from North America (DOT standards) to Europe (CE & RoHS), ensuring localized compliance and rapid delivery.
In the modern industrial landscape, the humble brass connector has evolved from a simple mechanical joint into a critical component of smart manufacturing. As a Global Leading Brass Connector Fittings Supplier, NHPC recognizes that Information Gain in SEO and engineering alike comes from deep technical insight. Brass, specifically alloys like CW614N and lead-free variants, remains the gold standard for pneumatic systems due to its superior machinability, corrosion resistance, and thermal stability.
The transition toward Industry 4.0 demands components that can withstand higher pressures and more frequent cycles. Our research into Semantic Search trends reveals that engineers are no longer just searching for "fittings"; they are looking for "high-cycle reliability," "vibration resistance," and "integrated flow control." NHPC addresses these specific user intents by integrating advanced sealing technologies (NBR, Viton) into our push-in and push-on fittings.
Our China Factory advantage is not merely about cost, but about "Total Value Management." Through vertical integration, we control the entire lifecycle—from the raw brass rod to the electroplating and final assembly. This ensures that our 360° rotatable male elbow fittings and DOT-certified air brake components meet the rigorous demands of the global transportation and automation sectors.
Solving complex fluid transmission challenges across diverse global environments.
DOT Air Brake Systems: Our brass fittings are specifically designed for heavy-duty trucks. They withstand extreme road vibration and temperature fluctuations from -40°C to +120°C.
Fire Protection (BESS): We provide flame-retardant pipe fittings (PE series) for lithium battery energy storage enclosures, ensuring safety in critical cooling and fire suppression lines.
Robotic Assembly Lines: Precision push-in fittings allow for rapid reconfiguration of pneumatic logic circuits, minimizing downtime in high-speed manufacturing environments.
Precision Regulation: Our flow control throttles (SL series) offer micro-adjustment capabilities for water and air flow, essential for laboratory and climate control systems.
NHPC stands at the nexus of the world's most robust industrial ecosystem. Our factory in Zhuji leverages:
Leading the next generation of fluid connection technology.
Developing fittings with integrated pressure and leak-detection sensors that communicate via 5G networks to industrial controllers.
Transitioning to 100% lead-free brass alloys (C46400) ahead of global environmental mandates, ensuring potable water safety and RoHS compliance.
Researching brass-reinforced composite fittings that offer the weight of plastic with the structural integrity of metal for aerospace applications.

Today, we are proud to stand as a trusted name in the industry, serving a diverse range of customers across the globe.
We specialize in the design, development, and manufacturing of a comprehensive range of pneumatic products. Our product includes push in fittings, push on fittings, pneumatic valves, quick connectors, PU pipes, hydraulic components and design service for custom pneumatic systems.
Q: What is the maximum operating pressure for your brass push-in fittings?
A: Most of our standard brass fittings are rated for up to 1.5 MPa (15 Bar), though specific high-pressure models can exceed this. Always consult the technical data sheet for your specific model.
Q: Do your fittings meet DOT standards for air brake systems?
A: Yes, we manufacture a dedicated line of DOT FMVSS 106 compliant fittings specifically for the North American heavy truck market.
Q: Can you provide customized ODM designs?
A: Absolutely. Our R&D team of 100+ technical staff can develop custom pipeline solutions based on your CAD drawings or performance requirements.
Q: How do you ensure corrosion resistance in harsh environments?
A: We offer various surface treatments, including nickel plating and chrome plating, which provide excellent resistance to salt spray and chemical exposure.
Q: What types of tubing are compatible with your fittings?
A: Our push-to-connect fittings are compatible with PU (Polyurethane), PA (Nylon), and PE (Polyethylene) tubing. For DOT fittings, we recommend reinforced nylon air brake tubing.
Q: What is the typical lead time for a bulk wholesale order?
A: Standard products ship within 10-15 days. Custom ODM orders typically take 3-4 weeks depending on the complexity of the design and tooling required.
Full range of adapters, reducers, and control valves for your industrial needs.
