Dongfeng KC Direct pipe joint connector 1606068-T68L0 for sale

Featuring a one-piece direct pipe structure, this connector is optimized to withstand high operating pressures commonly found in heavy-duty truck fluid systems. The integrated design minimizes weak points such as welded joints, enhancing its overall mechanical strength and durability. Rigorous pressure testing shows it can reliably operate under pressures up to 1.6 MPa (232 psi) – well above the standard working pressure of most Dongfeng KC truck brake and hydraulic circuits. Additionally, the smooth internal bore of the connector reduces fluid flow resistance, preventing pressure drops and ensuring efficient transmission of hydraulic or air pressure, which is critical for maintaining consistent braking performance and system responsiveness

The 1606068-T68L0 connector is crafted from premium cold-drawn carbon steel (SCM435 grade) with a zinc-nickel alloy plating finish. This material combination offers exceptional resistance to corrosion from road salts, moisture, and industrial contaminants – a common challenge for trucks operating in harsh environments like coastal areas or winter road conditions. The zinc-nickel plating also provides superior wear resistance, reducing surface damage during installation, disassembly, or long-term vibration. Furthermore, the steel material undergoes heat treatment to improve its tensile strength (minimum 800 MPa) and impact resistance, ensuring the connector can withstand the constant vibration and mechanical stress of heavy-duty truck operations without deformation or cracking

To ensure absolute leak-proof performance, the Dongfeng KC Direct Pipe Joint Connector is equipped with a dual-sealing system: a nitrile rubber (NBR) O-ring and a precision-machined sealing face. The NBR O-ring, selected for its excellent oil and temperature resistance (-40°C to 120°C), creates a tight seal between the connector and the mating pipeline, preventing fluid or air leakage even under extreme temperature fluctuations. The sealing face is machined to a surface roughness of Ra 0.8 μm, ensuring maximum contact area with the mating component and eliminating micro-gaps that could lead to leaks. This advanced sealing design not only maintains system pressure stability but also reduces maintenance costs by minimizing the need for frequent leak inspections and repairs

Designed with user convenience in mind, the 1606068-T68L0 connector features a standard pipe thread (compatible with metric or BSP threads based on Dongfeng KC specifications) that allows for quick and tool-free hand tightening, followed by final torquing with a standard wrench for secure installation. The connector’s compact size and lightweight design (weighing approximately 50-80 grams, depending on configuration) make it easy to handle and install in tight spaces within the truck’s engine bay or undercarriage. Additionally, the connector is marked with the part number, material grade, and manufacturing date for easy identification and traceability, simplifying inventory management and maintenance record-keeping. Its durable construction also ensures a long service life (typically 50,000+ kilometers under normal use), reducing the frequency of replacements and minimizing vehicle downtime
