The Sanheng 1CN / 1DN Hydraulic Adapter serves as a critical bridge for fluid systems requiring precise thread conversion. Engineered to transition Metric male DIN2353 threads to NPT configurations, this component ensures a reliable, leak-free pathway for oil, water, and gas distribution networks. When handling the adapter, the precision-cut threads offer a smooth, burr-free engagement that technicians can immediately feel during manual threading, reducing assembly friction and preventing galling.
Manufactured through rigorous CNC machining protocols, the solid body maintains exceptional structural integrity under fluctuating mechanical stresses. By standardizing connections between mismatched equipment—such as integrating European metric components with North American NPT systems—this adapter eliminates the need for complex pipeline redesigns. It provides procurement teams with a standardized, readily deployable solution that minimizes system downtime and simplifies inventory management across heavy machinery, fluid control setups, and industrial processing facilities.

Designed with Metric male DIN2353 thread and NPT external taper thread, this adapter resolves compatibility challenges between differing regional engineering standards. The precise thread pitch ensures smooth engagement, reducing installation torque while maximizing the mechanical hold.
The adapter strictly follows DIN 2353, ISO 8434-1, and ANSI B1.20.1 international standards. This rigorous adherence guarantees flawless integration into mainstream global hydraulic equipment, allowing maintenance teams to replace or upgrade components without worrying about dimensional deviations.
Available in Light Series (L) and Heavy Series (S), the design accommodates varying operational intensities. Spanning from extra-light (LL) to heavy-duty applications, these adapters are engineered to withstand extreme conditions, with the heavy series capable of enduring maximum working pressures up to 63 MPa, satisfying the most demanding industrial requirements.
To combat vibration and high-pressure surges, the adapter utilizes a dual-action sealing strategy. The 24° cone provides a secure ferrule bite, while the NPT tapered threads deform slightly upon installation to create a mechanical interference fit, ensuring zero-leakage performance even in heavy-vibration environments.
Buyers can procure the standalone adapter body or opt for a complete assembly kit. By selecting standard ferrules and nuts (such as those with an RN suffix), clients receive a ready-to-install package that significantly streamlines on-site assembly workflows and reduces parts sourcing complexity.
Beyond the standard straight-through design, this adapter series can be expanded to include bulkhead, swivel nut, and weld-on configurations. This structural versatility allows engineers to navigate complex, space-constrained pipeline layouts with ease.
Carbon steel adapters undergo a specialized Cr3+ zinc plating process, resulting in a distinct, uniform metallic sheen. This surface treatment acts as a highly effective barrier against environmental moisture and mild chemical exposure, providing essential corrosion resistance for general hydraulic setups. The smooth, plated finish also minimizes friction during wrench tightening, protecting the underlying metal from mechanical scoring.
For environments exposed to harsh elements or aggressive fluids, the stainless steel variant offers superior longevity. Treated with a meticulous passivation treatment, the metal develops a microscopic oxide layer that feels exceptionally smooth to the touch. This treatment actively prevents rust formation and chemical degradation, making it the definitive choice for offshore, chemical processing, or sanitary applications where material purity and extreme corrosion resistance are non-negotiable.
The DIN2353 to NPT Adapter is widely used in fluid pipeline connection scenarios requiring exact thread conversion, covering core industrial fields with specific operational demands:
Hydraulic Engineering: Facilitates pipeline transformations in construction machinery, metallurgical presses, and heavy earth-moving equipment. By resolving thread mismatches between imported European machinery and domestic North American attachments, it keeps critical infrastructure operational.
Petrochemical Industry: Deployed within oil and gas transmission lines and chemical medium delivery networks. The availability of highly corrosion-resistant materials ensures these adapters withstand continuous exposure to aggressive hydrocarbons and volatile chemical compounds without degrading.
General Manufacturing: Streamlines the assembly of compressed air distribution lines and cooling water circulation systems across CNC machining centers and electronics production facilities. It standardizes fluid connections, allowing facility managers to maintain a unified inventory of replacement parts.
Marine & Offshore Engineering: Engineered for the punishing conditions of shipboard hydraulic systems and offshore drilling platform fluid networks. The exceptional pressure tolerance and saltwater-resistant material options ensure reliable fluid power transmission in highly corrosive, moisture-rich marine environments.
The manufacturing process is anchored by advanced CNC machining centers that meticulously carve each adapter from solid metal bar stock. Operating under the strict guidelines of ISO 9001 and IATF 16949 quality management systems, every production phase—from initial raw material screening to final surface finishing—is subjected to full-link, high-precision quality control.
During the machining cycle, operators utilize calibrated thread plug and ring gauges to verify the exact pitch diameter and thread profile. This rigorous inspection protocol ensures that every Metric and NPT thread perfectly matches international dimensional tolerances. The result is a structurally stable component with crisp, well-defined threads that engage smoothly, eliminating the risk of cross-threading and ensuring absolute compatibility with standard threaded receptacles in the field.
1CN represents the light series (L), optimized for standard pressure applications where weight and space efficiency are prioritized. Conversely, 1DN designates the heavy series (S), featuring a thicker wall structure and enhanced material density to handle significantly higher pressure spikes and mechanical shocks.
This specific component acts as a transitional bridge, converting a Metric male DIN2353 thread (featuring a 24-degree inner cone) into a standard NPT (National Pipe Taper) external thread, facilitating secure connections across differing regional engineering standards.
Depending on your specific operational environment, you can select between Carbon Steel finished with Cr3+ zinc plating for standard industrial use, or passivated Stainless Steel for environments demanding maximum resistance to corrosive chemicals and extreme weather conditions.
It is primarily utilized by maintenance engineers and system integrators to resolve thread conversion in hydraulic and fluid pipeline systems. Common uses include adapting European hydraulic pumps to North American hoses, or standardizing pneumatic and liquid transmission lines across diverse manufacturing facilities.
