Product Overview
The YT50C01023P1 Cab Glass Rubber is a genuine OEM component specifically engineered for the Kobelco SK330-8 and SK350LC-8 excavators. This precision weatherstrip forms the critical seal between the cab glass and the cab frame, providing a watertight, dustproof, and noise-reducing barrier.
The Kobelco SK330-8 and SK350LC-8 are 33-35 ton class large excavators widely used in heavy construction, quarrying, mass excavation, and mining applications . The operator cab is subjected to constant exposure to rain, dust, vibration, and temperature extremes during normal operation. A properly sealed cab is essential for operator comfort, equipment longevity, and job site productivity.
The cab glass rubber (also known as window seal, weatherstrip, or windshield gasket) is a critical component that prevents water intrusion, dust ingress, and wind noise. It also provides cushioning between the glass and the metal frame, protecting the glass from vibration damage. Over time, exposure to UV radiation, temperature cycling, and ozone causes rubber seals to harden, crack, shrink, or become brittle . When this occurs, water leaks, dust infiltration, wind noise, and even glass damage can result. Replacing a deteriorated seal with this OEM YT50C01023P1 cab glass rubber restores cab integrity and operator comfort.

Signs Your Cab Glass Rubber Needs Replacement
Cab glass rubber is exposed to harsh environmental conditions and degrades over time. Replace your YT50C01023P1 cab glass rubber if you observe:
-
Water Leaks into Cab: Rainwater or wash water entering the cab around the windows or windshield. This is the most common symptom of failed cab seals.
-
Visible Cracking: Surface cracks or deep fissures in the rubber material, particularly at corners or along the glass edge.
-
Hardening or Brittleness: The rubber feels hard and inflexible rather than soft and resilient, indicating UV and ozone degradation.
-
Shrinkage: The rubber has shrunk, leaving gaps at the corners or pulling away from the glass edges.
-
Dust Infiltration: Fine dust entering the cab around the glass, visible on the dashboard or interior surfaces.
-
Wind Noise: Excessive whistling or roaring noise at speed, indicating air leakage through the seal.
-
Glass Rattle: The glass moves or rattles in the frame when closing doors or during operation, indicating the seal no longer provides adequate cushioning.
-
Water Stains or Corrosion: Water stains on interior trim or signs of corrosion on metal components around the glass.
-
Deformation: The seal has become permanently compressed or deformed, no longer maintaining contact with the glass.
-
Previous Repairs: The existing seal shows evidence of silicone or sealant applied as a temporary patch.
Benefits
Why choose our YT50C01023P1 Cab Glass Rubber for your Kobelco SK330-8 or SK350LC-8?
-

Improves Operator Comfort: Reduces wind noise, dust infiltration, and temperature transfer, creating a more comfortable, less fatiguing work environment.
-
Protects Cab Interior: Prevents water damage to electrical components, trim panels, seat fabric, and control systems.
-
Extends Glass Life: Proper cushioning protects the glass edge from vibration damage and stress fractures.
-
Reduces HVAC Load: A properly sealed cab maintains temperature more effectively, reducing strain on the heating and air conditioning system.
-
Maintains Equipment Value: A dry, well-sealed cab preserves the machine’s interior condition and resale value.
-
Improves Safety: Clear, unobstructed visibility through properly sealed glass enhances job site safety.
-
OEM-Grade Reliability: Genuine Kobelco part ensures correct material specifications, dimensional accuracy, and long service life.
Cab Glass Seal Types on SK330-8 / SK350LC-8
Based on industry standards for large excavator cabs, rubber seals like YT50C01023P1 are used in the following applications:
The YT50C01023P1 may be used for one or more of these applications depending on the specific cab configuration of your SK330-8 or SK350LC-8. Verify with your parts diagram before ordering.
Why Cab Glass Rubber Degrades
Rubber components like cab glass weatherstrips are subjected to constant environmental stress:
-
UV Radiation: Sunlight breaks down rubber polymers, causing surface cracking and loss of elasticity.
-
Ozone: Atmospheric ozone attacks rubber compounds, leading to cracking even without UV exposure.
-
Temperature Extremes: Repeated expansion and contraction from hot/cold cycling accelerates material fatigue.
-
Moisture: Water absorption can lead to swelling, followed by shrinkage and cracking as the water evaporates.
-
Dirt and Abrasion: Dust particles embedded in the seal can abrade the glass and the seal surface.
As noted in the SK330-8 Shop Manual, seals, O-rings, and rubber components, if once disassembled, are not reusable . For cab glass rubber that has hardened or cracked, replacement is the only permanent solution.
Installation Tips
-
Professional Installation Recommended: Cab glass replacement and weatherstrip installation requires specialized tools and techniques. Professional installation by qualified technicians is strongly recommended.
-
Remove Old Seal Carefully: Use a plastic trim tool to avoid scratching the glass or frame. Soften the old seal with a heat gun if necessary.
-
Thoroughly Clean the Frame: Remove all old adhesive, dirt, and debris from the glass channel before installing the new seal.
-
Apply Glass Primer (if recommended): Use the recommended glass primer on the glass edge to ensure proper adhesion of the seal.
-
Lubricate for Installation: Apply soapy water or a rubber lubricant to help the seal slide into position.
-
Seat Corners Properly: Pay special attention to corners, ensuring the seal is fully seated without gaps.
-
Check for Smooth Glass Movement: For opening windows, verify the glass moves smoothly without binding.
-
Water Test After Installation: After installation, perform a water test by spraying water around the seal area while observing for leaks.
-
Allow Time to Set: If adhesive is used, allow the recommended cure time before operating the machine.
