The 1CT (Light Series) and 1DT (Heavy Series) adapters are professionally engineered for seamless thread conversion between Metric DIN standard and BSPT tapered thread in high-pressure hydraulic systems. It eliminates the need for complex piping workarounds, directly bridging two global thread standards for fluid pipeline connection. Made of integral forged blank with multi-axis CNC precision machining, the adapter features burr-free, smooth threads for frictionless engagement, and a mirror-finished internal bore to minimize fluid turbulence and pressure loss. With professional anti-corrosion surface treatment, it reliably conveys hydraulic oil, industrial water and compressed gas, effectively resisting vibration, pressure spikes and harsh environmental erosion, ensuring long-term zero-leakage operation of industrial fluid systems.
Manufactured in full compliance with DIN and ISO international industry standards, all thread dimensions and tolerances are strictly controlled. The product passes 96-hour neutral salt spray test with reliable corrosion resistance, with working pressure up to 25 MPa for light series and 40 MPa for heavy series. Complete dimensional drawings, thread parameters and pressure rating data can be provided according to customer requirements, supporting direct replacement of standard parts.
Seamless Cross-Standard Conversion: Directly bridges Metric DIN male thread and BSPT tapered male thread, eliminating complex multi-part piping workarounds and reducing potential leak points.
High-Density Forged Structure: Integral hot forging eliminates internal micro-voids, enhances resistance to mechanical shock and vibration fatigue, ensuring long-term structural stability under high pressure.
Optimized Flow Dynamics: Mirror-finished internal bore minimizes fluid turbulence and pressure loss, maintains system efficiency and reduces heat generation during high-velocity fluid transmission.
Superior Corrosion Resistance: Professional surface treatment forms a dense protective barrier, effectively resists rust, chemical erosion and moisture ingress, extending service life in harsh environments.
Secure & Easy Installation: Precisely machined hexagonal flats provide stable wrench grip for accurate torque application, preventing slippage and deformation, ensuring a tight leak-free seal during assembly.
Carbon Steel (Cr3+ Zinc Plated)
Adopts eco-friendly trivalent chromium zinc plating process, with excellent oxidation resistance and high tensile strength, cost-effective for conventional hydraulic systems, construction machinery and general industrial working conditions.
Stainless Steel (Passivation)
Through rigorous professional passivation treatment, it forms a stable protective oxide layer, with outstanding acid, alkali and salt spray corrosion resistance, perfectly suitable for marine, petrochemical and other highly corrosive harsh working environments.
This Metric to BSPT hydraulic adapter is widely used in cross-standard thread conversion and pipeline connection scenarios in various core industrial fields:
Construction & Earthmoving Machinery: Hydraulic pipeline standard conversion for excavators, bulldozers, loaders and other mobile heavy equipment, adapting to high-vibration field working conditions.
Industrial Manufacturing: Pipeline connection for automated production lines, hydraulic stations, machine tools, compressed air and cooling water circulation systems.
Agricultural Equipment: Hydraulic system piping for high-horsepower tractors, combine harvesters and other agricultural machinery, resistant to outdoor harsh weather and soil erosion.
Petrochemical & Marine Engineering: Medium transmission pipelines for oil and gas, chemical processing systems, ship equipment and offshore platforms, with corrosion-resistant material options for harsh environments.
The adapter body is formed by high-tonnage integral hot forging to optimize metal grain structure, ensuring dense internal matrix and excellent burst pressure resistance. Metric and BSPT threads, as well as the internal flow path, are processed by multi-axis CNC machine tools with micron-level precision. Each batch undergoes strict dimensional inspection, thread gauge verification and pressure sealing test before delivery, fully complying with international standard requirements, ensuring stable and reliable long-term operation under extreme high pressure.
The pressure rating heavily depends on the specific size and series configuration (Light 'L' or Heavy 'S' series). Generally, our Light series is designed to handle up to 25 MPa, while the Heavy series is engineered for extreme applications, safely managing pressures up to 40 MPa. Please refer to our detailed specification table for exact ratings per part number.
Trivalent chromium (Cr3+) plating offers superior corrosion resistance compared to older hexavalent methods, while being entirely eco-friendly and compliant with modern global environmental directives. It provides a tough, self-healing barrier against oxidation, significantly extending the life of the carbon steel fitting.
Yes, the precision-machined threads and robust material composition make them highly suitable for compressed gas systems, in addition to standard hydraulic oil and water applications. We recommend using appropriate thread sealants designed specifically for gas media to ensure absolute integrity.
While standard catalog items are typically dispatched from our extensive stock immediately, custom-engineered fittings generally require an estimated 30 days for full production. This timeframe includes CAD design verification, CNC programming, precision machining, and comprehensive quality testing.
Absolutely. We maintain strict traceability for all our raw materials throughout the manufacturing process. Comprehensive material test reports and certificates of compliance can be provided upon request to satisfy your internal quality management and regulatory requirements.
