[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a Sino-French OE specialist in professional wiper system solutions, is pleased to introduce its heavy-duty Bone Brush Wiper Blade (Model: CAP138000) designed specifically for large and medium-sized passenger buses and urban transit vehicles. Featuring a 1000mm rubber strip length, a compact bone-brush structure, and outstanding scraping clarity, this blade brings OE-grade windshield visibility to the high-frequency, high-demand environment of professional public transportation — where driver clarity is directly linked to passenger safety.
1000mm Length: Full Coverage for Wide Bus Windscreens At 1000mm in rubber strip length, the CAP138000 is engineered for the expansive windscreens of medium and large-capacity buses, intercity coaches, and city transit vehicles. A shorter blade on a wide windscreen leaves un-cleared zones at the edges — creating visual blind spots that are unacceptable in passenger transport where the driver must maintain maximum situational awareness at all times. The CAP138000's 1000mm length ensures complete, uninterrupted sweep coverage across the full width of the windscreen, meeting the demanding visibility standards of professional bus operations worldwide.
Bone Brush Structure: Compact, Silent, and Resilient The CAP138000 uses a compact bone brush (conventional frame) architecture that has been optimized for the specific loading conditions of bus wiper systems. The rigid frame distributes blade pressure evenly across the full 1000mm length, maintaining consistent glass contact even under the high air resistance loads generated at highway speeds or in crosswind conditions. Despite its structural robustness, the design achieves genuinely quiet operation — a key comfort factor for bus passengers and drivers who spend hours in the vehicle cabin. The compact profile also reduces wind lift and buffeting at speed, maintaining wiper contact throughout the sweep arc.
500,000-Cycle Durability with Superior Corrosion and Aging Resistance The rubber element of the CAP138000 is formulated for superior corrosion resistance and aging resistance, maintaining its flexibility, sealing properties, and scraping efficiency across a tested lifespan of more than 500,000 wipe cycles. This durability is critical in bus fleet operations, where wipers must perform reliably across thousands of operating hours and diverse environmental conditions — from high-UV summer service to cold, brittle winter temperatures. The rubber's aging resistance prevents the cracking, hardening, and loss of flexibility that cause premature streaking in lower-quality blades, protecting both passenger safety and maintenance budgets.
Three U-Connection Widths: Flexible Fleet-Wide Compatibility The CAP138000 is available with a U-type connection in three standardized widths — 22mm, 25.2mm, and 27mm — covering the full range of wiper arm U-slot specifications used across major global bus platforms. This multi-width availability eliminates the procurement complexity of sourcing different blade models for mixed bus fleets, allowing fleet managers to standardize on a single high-performance blade SKU across multiple vehicle types. The low-reflectivity surface treatment (below 40% reflectance) can be customized to meet specific fleet or regulatory requirements, ensuring that the blade remains visually recessive and glare-free in the driver's field of view.
