The WG9000361019 bamboo insert is a specialised solution for terminating or connecting 4 mm push‑in lines in heavy‑duty trucks where space is at a premium. Its unique “bamboo” profile – featuring a series of fine, ridged steps – provides a secure, vibration‑resistant grip on the hose while maintaining a smooth, uninterrupted flow path. This miniature insert is particularly valuable in air brake pilot circuits, where it seals unused ports or adapts between different line sizes, and in fuel systems, where it provides a reliable end‑stop for return lines. The robust brass construction and precision‑machined surface ensure a leak‑proof seal that withstands high pressures and temperature extremes, all within a 6 mm length that fits into the tightest spaces. By using the genuine WG9000361019, you achieve a reliable, durable connection with minimal pressure loss and maximum system integrity – directly translating to lower operating costs and increased vehicle uptime.
Secure Miniature Grip
The stepped “bamboo” profile provides excellent retention on 4 mm push‑in hoses, preventing accidental disconnection in tight spaces.
Leak‑Proof Sealing
Precision‑machined surface ensures a tight seal against the hose interior, eliminating fluid bypass even at 4 mm diameter.
Ultra‑Compact L6 Design
The 6 mm overall length allows installation in the most space‑constrained areas of modern truck systems.
OEM‑Exact Fit
Manufactured to Sinotruk’s original specifications – direct replacement with no modifications.

The WG9000361019 bamboo insert is extensively used across the HOWO and Sitrak model ranges, particularly in systems that require secure termination or transition of 4 mm push‑in lines in compact spaces. Typical applications include:
The WG9000361019 bamboo insert is manufactured with uncompromising quality, ensuring it outperforms generic aftermarket alternatives. Made from premium brass billet and CNC‑machined to exacting tolerances, every step and sealing surface is flawlessly formed, even at this miniature scale. The nickel‑plated finish provides a hard, corrosion‑resistant layer that resists rust, chemicals, and road salts, ensuring long‑term durability. The unique bamboo profile is optimised to provide maximum retention without damaging the hose interior, while the smooth internal bore ensures unrestricted flow in the small 4 mm diameter. Each insert is pressure‑tested to verify leak‑free performance and undergoes dimensional inspection to guarantee perfect fitment in OEM ports. This dedication to quality delivers reliable, maintenance‑free operation, reducing downtime and extending the service life of your vehicle’s fluid systems.
CNC Precision
Every dimension, including the fine stepped profile, machined to micron accuracy for perfect fit and sealing.
Corrosion Protection
Nickel plating offers robust resistance to rust, moisture, and harsh chemicals, even in miniature sizes.
Genuine OEM Quality
Built to Sinotruk’s original specifications – guaranteed fit, form, and function.
100% Pressure Tested
Every insert tested for leakage at rated pressure – reliability guaranteed.
Installing the WG9000361019 bamboo insert is straightforward, but proper technique ensures a leak‑free, durable connection. For the push‑in application, insert the insert into the hose end until it bottoms out – the stepped profile will engage and provide a secure grip. If used as a plug, ensure the hose is cut cleanly and square, then push the insert fully into the open end. No additional sealant or tools are required for the push‑in connection. After installation, pressurise the system and check for leaks with soapy water. If the insert is in a high‑vibration zone, periodically inspect the insertion depth to ensure it remains fully seated. Regular inspection for corrosion or damage will help maintain long‑term reliability.
Selecting the WG9000361019 genuine bamboo insert directly impacts the safety and reliability of your HOWO or Sitrak truck’s miniature pneumatic and hydraulic circuits. Inferior inserts can lead to leaks, pressure drops, and contamination – all of which compromise brake performance, fuel efficiency, and engine cooling. By using a genuine OEM component that adheres to Sinotruk’s exacting standards, you guarantee a perfect seal, optimal flow, and long‑term durability, even in the smallest lines. Fleet operators and workshop professionals consistently trust this insert to maintain system integrity, reduce unplanned downtime, and lower overall maintenance expenses. With its proven precision and robust construction, it is the definitive choice for professionals who demand excellence.
“We have standardised on the WG9000361019 bamboo inserts for all our 4 mm air brake pilot and fuel line terminations. The miniature stepped design provides a secure grip that never loosens, and the quality is exceptional – zero leaks since we switched. This is the only insert we trust for our fleet.”
The WG9000361019 bamboo insert is designed to fit a broad range of HOWO and Sitrak heavy‑duty trucks, including HOWO‑7, HOWO T series, HOWO A7, Sitrak C7H, T7H, and M5G models. It is a direct replacement for the original insert used in air brake, fuel, and cooling systems across these vehicle families. The NW4 (4 mm) size is compatible with standard miniature push‑in hoses and fittings, making it ideal for compact pilot and control circuits. Always verify the OEM number WG9000361019 on the part or packaging to ensure correct application.
HOWO and Sitrak trucks are exposed to the harshest environments – from extreme cold to desert heat, from constant vibration to corrosive road salts. The WG9000361019 bamboo insert is engineered to withstand these challenges, even at its miniature 4 mm size. Its brass construction and nickel plating resist corrosion and chemical attack, while the stepped profile maintains a secure grip on the hose even under severe vibration and thermal cycling. The compact 6 mm length ensures minimal flow restriction and stable pressure distribution. This insert is built for longevity, providing leak‑free service over the vehicle’s lifetime and reducing the frequency of replacements.
Wide Temperature Range
Reliable from -40°C to +120°C – no loss of sealing or structural integrity.
Vibration Resistant
Stepped profile maintains a tight grip, preventing disconnection under constant vehicle vibration, even in miniature lines.
Corrosion Protection
Nickel plating provides long‑term resistance to moisture, salt, and aggressive chemicals.
High Pressure Capability
Rated for 20 bar pneumatic and 10 bar hydraulic – suitable for most heavy‑duty systems, even at 4 mm diameter.
The WG9000361019 bamboo insert is supplied in protective packaging to ensure safe delivery and convenient storage. Each insert is individually wrapped to prevent surface damage.
