Superior sealing for left door window glass – The OEM LG1611711008 Left Window Glass Sealing Strip Assembly is a high‑quality EPDM rubber gasket specially engineered to create a water‑tight, dust‑proof seal between the left‑side window glass and the door frame on SINOTRUK HOWO, SHACMAN, and other heavy‑duty trucks. It effectively eliminates water ingress, wind noise, and dust entry, keeping the cab dry, quiet, and comfortable.
This sealing strip assembly is manufactured from premium automotive‑grade EPDM rubber, offering outstanding resistance to ozone, UV radiation, extreme temperatures, and weathering. For guaranteed fitment and long‑lasting sealing performance, always choose genuine Sinotruk Homan parts.
The LG1611711008 Left Window Glass Sealing Strip Assembly features a multi‑chamber profile with an integrated locking barb and a hollow sealing bulb. It compresses evenly to accommodate glass movement during raising and lowering, providing a reliable barrier against leaks while also dampening window vibration. Its durable EPDM construction ensures years of trouble‑free service.
The LG1611711008 Left Window Glass Sealing Strip Assembly is engineered with a three‑zone profile: a rigid barbed anchor leg that locks securely into the door frame channel, a flexible hollow sealing bulb that compresses against the window glass, and a smooth outer lip that deflects water and debris. This geometry ensures consistent sealing force even when the glass is lowered or raised, preventing water from entering the door cavity and reaching sensitive components like the window regulator and speakers.
The material is 100% EPDM rubber, specifically formulated to pass stringent DIN 53505 hardness test (70 Shore A) and the SAE J200 aging test (70°C for 70 hours, no cracking). Unlike cheap PVC or sponge seals, this EPDM compound does not shrink, harden, or crack after years of UV exposure. It also has excellent resistance to road salts, diesel fumes, and car wash chemicals.
Fleet operators using the LG1611711008 report a 95% reduction in left‑window leaks and a noticeable decrease in wind noise at highway speeds. The strip also prevents dust ingress, keeping the cab cleaner and protecting electronic window regulators from moisture damage.
Resistant to ozone, UV, acid rain, and extreme temperatures (-40°C to +120°C). No cracking or hardening over time.
Hollow bulb design compresses evenly, creating a high‑pressure seal that passes water spray tests per ISO 20653.
Multi‑chamber profile absorbs vibration, eliminating glass rattle and reducing interior wind noise.

The LG1611711008 is produced by continuous vulcanization extrusion, ensuring a uniform cross‑section along the entire length. The EPDM compound is mixed in a closed‑mill banbury mixer, ensuring consistent dispersion of carbon black, anti‑oxidants, and UV stabilizers. The strip is then cut to the exact length for the left door window and de‑burred to prevent sharp edges.
The sealing bulb is designed with a slight oval shape that, when compressed, creates a progressive sealing force. This allows the seal to accommodate glass thickness variations of ±1 mm without losing effectiveness. The barbed anchor leg has a fish‑scale texture that grips the steel channel, preventing the strip from pulling out during window operation.
Each batch of rubber is tested for hardness, tensile strength, and accelerated aging (70°C for 168 hours). A sample of the finished strip is subjected to a water spray test (ISO 20653 IPX4) and a compression set test (22h at 70°C). Only strips with less than 25% compression set are released for sale.
EPDM rubber used in the LG1611711008 has an ethylene content of over 70%, giving it excellent resistance to ozone cracking (ASTM D1171 rating 0). It also withstands prolonged exposure to road salts, diesel fuel, and mild acids without swelling or degradation. The black color is integral (carbon‑black filled), so the seal will never fade to gray.
The material has been validated for 5 years of outdoor exposure in Florida and Arizona proving grounds, with no surface cracking or significant loss of elasticity. For arctic conditions, the seal remains flexible down to -40°C without becoming brittle.
Unlike sponge rubber, which absorbs water, this dense seal does not wick moisture, eliminating the risk of rust behind the door panel.
The LG1611711008 is a direct replacement for the original left‑door window seal on SINOTRUK HOWO and SHACMAN cabs. It fits into the existing channel without trimming (supplied pre‑cut to size for each cab variant). No adhesive or special tools are required – a simple plastic trim tool and a rubber mallet are sufficient.
To replace an old seal: remove the door inner panel, pull out the old seal, clean the channel, lubricate the new seal with soapy water, push the barbed leg into the channel, and then reinstall the window glass. The seal will self‑lock into position.
The seal can also be used on other doors (right side, rear) as long as the channel geometry matches; consult the application guide.
To replace a worn left‑door window seal with the LG1611711008, follow these steps: 1) Lower the window glass fully and remove the door interior trim panel.
2) Carefully pull the old seal out of the channel using pliers, starting at a corner. Remove all remnants.
3) Clean the metal channel with a wire brush and solvent. Remove all rust and debris. Inspect for sharp edges; deburr if necessary.
4) Apply a thin layer of rubber lubricant or soapy water to the channel and to the barb of the new seal.
5) Starting at the bottom center, push the barbed leg of the new seal into the channel using a blunt plastic trim tool. Work your way around the perimeter. Ensure the seal is fully seated without twists.
6) Raise the window glass and verify that it slides smoothly without binding. The seal should compress evenly.
7) Reinstall the door trim panel. Run a water hose over the window to check for leaks. If any leaks are found, use a sealant tool to lift the lip and apply a small bead of silicone.
The LG1611711008 requires no routine maintenance. However, inspect the seal annually for cuts, tears, or flattening of the sealing bulb. If the rubber feels hard or shows cracks, replace it.
If water leaks appear, first check that the window is fully closed and the seal is seated properly; sometimes the seal may have rolled out of position. Use a plastic trim tool to re‑seat the lip. If leaks persist, the channel may be corroded – clean and apply a urethane sealant.
Do not use petroleum‑based lubricants on the seal – they can attack EPDM. Only use silicone‑based or water‑based rubber lubricants.
Each batch of LG1611711008 seals is tested to meet OEM and international standards. Tests include: (1) Tensile strength and elongation (DIN 53504), (2) Hardness (Shore A), (3) Compression set (22h at 70°C, ≤25%), (4) Ozone resistance (ASTM D1171, 50 pphm, 72h, zero cracks), (5) UV weathering (500h QUV, no color change), (6) Low‑temperature flexibility (−40°C, no cracking).
(7) Water ingress test (ISO 20653 IPX4), (8) Pull‑out force test (≥50 N/cm). The manufacturing facility is IATF 16949 and ISO 9001 certified. A certificate of conformance is supplied with each shipment.
The seal also meets the requirements of GL‑E 4.4 for railway applications, ensuring exceptional durability.
A North American fleet of 150 HOWO trucks suffered from persistent left‑window leaks that caused damage to door speakers and window regulator motors. After replacing all seals with the LG1611711008, the fleet reported zero leaks in the first year and a 90% reduction in wind noise complaints. Drivers also noted less dust entry on gravel roads.
A South African mining company using SHACMAN dump trucks in high‑dust conditions found that the OEM seal lasted twice as long as aftermarket sponge seals, which hardened and cracked after 6 months. The EPDM material remained flexible even under constant sun exposure, reducing replacement costs by 60%.
Each LG1611711008 Left Window Glass Sealing Strip Assembly is coiled in a sealed, dust‑proof plastic bag and packed in a cardboard box. The bag is labeled with the OEM number, batch code, and a QR code for authenticity.
A tamper‑evident hologram sticker is affixed to the box. Scanning the QR code leads to the SINOTRUK Homan verification portal. Counterfeit seals are often made of PVC or low‑grade rubber that hardens quickly or has an unpleasant smell. Genuine EPDM strips have a smooth, matte finish, a slight rubber odor, and a clearly visible extrusion seam.
Purchase only from authorized distributors. The genuine LG1611711008 comes with a 12‑month / 100,000 km warranty.
