Explore our high-performance product range designed to secure vital fluid lines and prevent leaks under extreme temperatures and pressures.
In modern cooling systems, the radiator hose clamp plays a small but critically vital role in keeping vehicles, generators, and heavy machinery running. These components must establish a tight, uniform seal around radiator and coolant hoses, preventing pressure loss, fluid leaks, and systemic failure. Industrial engines operate at higher internal temperatures and pressures than ever before, which requires clamps with precise clamping forces, corrosion resistance, and thermal fatigue resistance.
When evaluating suppliers, engineers and global procurement directors focus on key criteria: material grades (from economical W1 to premium W5 stainless steel), locking mechanism design (worm gear, constant tension, or spring-loaded T-bolts), and production quality. Selecting the right clamp depends on matching the specific operational environment with the correct material, torque rating, and size range.
Widely used for automotive and industrial hose connections, worm drive hose clamps feature a helical threaded screw that interlocks with a series of slots in the band. Our American and German DIN 3017 standards deliver high torque capability and reliable performance.
Engineered with a Belleville spring mechanism or inner lining to expand and contract dynamically during temperature fluctuations. This constant pressure design prevents cold leaks in engine cooling systems.
Designed for high-pressure turbocharger, intercooler, and exhaust connections, T-bolt clamps provide exceptional tensile strength and high band tension, keeping high-pressure lines secure.
Evolving from our roots as Jinchaoyang Mould Company (founded in 2002), we maintain an in-house tooling center. This allows us to rapidly customize clamps, reduce lead times, and optimize stamping processes with high dimensional accuracy.
Located in Tianjin, a premier steel production and maritime port city in Northern China, we source high-grade raw materials directly from leading domestic mills. Every batch undergoes chemical composition and tensile testing.
With manufacturing facilities operating in Tianjin, Hebei Province (established 2023), and Chongqing (established 2024), we scale production to meet large international orders while securing local logistics for domestic and export shipping.
Our engineering team has documented critical technical details to help purchasing managers and automotive engineers make informed decisions.
Most of the clamps are made of different grades of stainless steel. Usually, customers will use magnets to detect the quality of the material. If there is magnetism, the material is not good. In fact, the opposite is true. Magnetism means that the raw material has high hardness and high strength. Because the currently made clamps are usually made of austenitic stainless steel such as 201, 301, 304, and 316, after heat treatment, the raw materials can be completely non-magnetic, but the raw materials used to produce the clamps must meet the hardness and tensile strength of the product itself. So the hardness and tensile strength can only be met by the cold rolling process, which requires the soft material to be rolled into a thinner cold-rolled strip. After cold-rolling, they will indeed become harder and also generate a magnetic field.
At present, the galvanized layer on the surface of carbon steel plated screws plays a lubricating role. Most steel screws in DIN3017 clamps are also galvanized, which can play a lubricating role. If you do not need zinc plating, you need wax compound as a lubricant. At any time, the wax compound will be dried, the temperature during transportation or the harsh environment will cause the loss, so the lubrication will decline, so it is recommended that the steel screw is also galvanized.
T-bolt clamp with spring are commonly used in heavy truck coolant and charge air systems. The purpose of the spring is to mediate the expansion and contraction of the hose connection. Therefore, when installing this clamp, you must pay attention to the end of the spring can not be completely down. If there are exactly two problems in the end: one is that the spring loses its function of mediating thermal expansion and contraction and becomes a solid spacer; although this may shrink somewhat, there is absolutely no way to adjust to thermal expansion and contraction. The second is the heating of the fastening system, the hose will have excessive fastening pressure, damage the pipe fittings, and greatly reduce the service life of the fastening system.
At present, our factory maintains sufficient raw materials, sourced from top domestic steel mills. After each batch of raw materials arrives, our QC department tests the materials for hardness, tensile strength, and dimension. Once verified, they are stored in our raw material warehouse to maintain uninterrupted production schedules.

Select from our specialized hose clamps, manufactured to meet strict international specifications:
The international supply chain for fasteners and industrial pipe clamps has adjusted to changes in energy networks, environmental legislation, and automotive design. Procurement directors look beyond per-unit cost; they focus on total cost of ownership (TCO) and supply chain continuity.
Electric Vehicles (EVs) have changed vehicle thermal management design. While internal combustion engines rely on large-diameter hoses, EVs use complex, multi-route cooling systems for battery packs, power electronics, and electric motors. These systems require lightweight, corrosion-resistant, and vibration-proof clamps to prevent glycol coolant leaks.
Global buyers in North America and Western Europe require complete material traceability under standard quality protocols. Maintaining clear chemical test reports and raw material certifications (for steel batches) helps verify that products conform to specified tensile strengths and corrosion resistance ratings.
Industrial buyers require reliable logistics partners to avoid assembly line downtime. Operating multiple manufacturing facilities helps balance production loads, stabilize lead times, and maintain supply security during regional disruptions.
