Achieve absolute connection security with the 61200040023 Clamp, a rugged, precision‑engineered fastening device designed to handle the high pressures, vibrations, and temperature swings of modern diesel trucks. This clamp delivers uniform circumferential force, ensuring hoses and pipes remain tightly sealed without damage. As a trusted component within the genuine Howo/Sitrak truck parts portfolio, the 61200040023 is crafted to exact OEM dimensions, guaranteeing a flawless replacement for HOWO, Sitrak, and compatible vehicles. Whether you are servicing cooling systems, air intake ducts, or fuel lines, this clamp provides the durability and clamping consistency needed to prevent leaks, reduce fluid loss, and keep your fleet operating at peak efficiency.
The 61200040023 is built to outperform standard worm‑drive clamps through a combination of advanced materials and meticulous design. Its band is stamped from high‑grade galvanised steel with a consistent thickness, providing flexibility during installation while maintaining structural integrity under load. The inner surface is deburred and smooth to protect soft silicone or rubber hoses from abrasion. The housing is reinforced with a deep‑drawn channel that prevents band distortion, even when high torque is applied to the screw. The precision‑rolled threads of the screw engage with a fully captured nut, ensuring that tightening force is translated directly into clamping pressure without any lost motion or binding.
Corrosion Shield – The zinc‑plated finish of the 61200040023 provides a robust barrier against road salts, moisture, and engine chemicals, ensuring a long, reliable service life.
Even Pressure Distribution – The wide band design and smooth inner surface ensure that clamping force is spread uniformly, eliminating stress risers that can weaken hoses.
Wide Temperature Range – The 61200040023 maintains its clamping force from -40°C to +120°C, making it suitable for every climate.
Self‑Locking Threads – The screw design incorporates a mechanical locking feature that resists loosening from vibration, a common cause of hose disconnection.
The 61200040023 is dimensionally identical to the original clamp used in a wide variety of HOWO and Sitrak applications. Its band width of 12 mm and diameter range of 40–60 mm covers the most common hose connections on engines, radiators, charge‑air coolers, and fuel filtration systems. The hex‑head slotted screw (M6 x 1.0) allows for both screwdriver and socket wrench tightening, providing flexibility for technicians. This clamp is regularly specified for models such as the HOWO T7H, ZZ4257, Sitrak C7H, and many others. By selecting the 61200040023, you eliminate fitment guesswork and ensure that your connection points are secured with the correct clamp geometry.
Fleet trials have demonstrated that the 61200040023 significantly reduces the incidence of clamp‑related leaks compared to generic alternatives. Its consistent clamping force prevents the need for frequent re‑tightening, and the smooth band edge extends hose life by eliminating cuts and abrasions. With this clamp, maintenance teams can be confident that their repairs will last, reducing unplanned stops and service calls.
To get the most from your 61200040023, follow these installation steps carefully. Start by ensuring the hose and fitting are clean and dry, with no grease or old sealant on the sealing surface. Slide the clamp over the hose and position it directly over the barb or raised bead of the fitting. The screw mechanism should be accessible for tightening. Using a torque‑limiting driver or a calibrated screwdriver, tighten the screw until the band is snug, then apply an additional quarter‑turn (approximately 2–3 Nm). Avoid over‑tightening, as this can deform the hose or strip the threads.
After installation, perform a visual inspection to confirm that the clamp is square on the hose and that no portion of the band overlaps the hose edge. For critical systems like turbocharger boost lines or high‑pressure fuel returns, a pressure test is recommended. The 61200040023 is designed to maintain its clamping force over time, but periodic checks—especially after the first heat cycle—are a good practice. With proper care, this clamp will provide a lifetime of leak‑free connections.
Our production of the 61200040023 adheres to ISO 9001 quality management standards. Each batch of steel coil is verified for composition and thickness before stamping. During manufacturing, the band edges are precision‑deburred to ensure they are smooth and safe for hose contact. The screw and housing assemblies are 100% inspected for thread fit, and each completed clamp is subjected to a torque test to confirm that it reaches the specified clamping force without deformation. A random sample from every shift is also placed in a salt‑spray chamber to validate corrosion resistance.
Additionally, we perform destructive pull‑off tests on samples to measure the ultimate tensile strength of the band and the holding capacity of the locking mechanism. These tests ensure that the 61200040023 not only meets but often exceeds OEM performance requirements. With this rigorous attention to detail, you can be certain that every clamp you install will deliver the same high level of performance and reliability.
Professional mechanics and fleet maintenance teams choose the 61200040023 because it delivers tangible benefits: fewer comebacks, lower fluid consumption, and faster repairs. The clamp’s consistent clamping force eliminates the need for repeated re‑tightening, and its corrosion‑resistant finish ensures that it can be removed easily even after years of service. Many workshops report that using this clamp has nearly eliminated leak‑related warranty claims, improving both customer satisfaction and shop profitability.
The 61200040023 is also available in bulk packs, making it cost‑effective for large fleets. Its standardised dimensions mean that a single part number can cover multiple hose sizes within the 40‑60 mm range, simplifying inventory. When you choose this clamp, you are investing in a product that has been proven in the field, backed by rigorous testing and trusted by OEMs worldwide.
In conclusion, the 61200040023 Clamp is a vital fastening component that combines strength, precision, and long‑term durability to keep your HOWO or Sitrak truck’s fluid and air systems leak‑free. Its robust galvanised construction, smooth band design, and reliable screw mechanism ensure that hoses remain securely attached under the most demanding conditions. By choosing this genuine OEM‑grade clamp, you protect your engine from coolant loss, boost leaks, and fuel contamination, all of which can lead to costly breakdowns.
Don’t settle for generic clamps that may fail prematurely. Upgrade to the 61200040023 and experience the peace of mind that comes with using a component engineered specifically for your vehicle. With its proven track record, widespread availability, and outstanding performance, this clamp is the definitive choice for professionals who demand reliability.
