Custom Waterproof & Heat-Resistant Silicone Rubber Irregular, Y-Type Seals
Engineered for Extremes. Customized for You.
From precision industrial equipment to outdoor waterproof components, our custom silicone Y-shaped and irregular gaskets maintain excellent elasticity across a wide temperature range of -40°C to 260°C, offering IP68-level dust and water resistance. Whether you require special cross-sections, non-standard dimensions, or specific hardness, we can deliver a one-stop solution from mold opening to mass production.
Product Advantages (USP):
1. Strict Environmental Stability
◦ Temperature Range: -40°C ~ +260°C (some special formulations可达 300°C)
◦ Water Resistance Rating: IP68 (capable of withstanding continuous submersion)
◦ Weather Resistance and Anti-aging: Passes 1000-hour UV and ozone tests
2. Fully Customized According to Drawings
• Supports Y-type, V-type, lip-shaped, and any irregular cross-sections
• Inner diameter, outer diameter, thickness, and curvature can be replicated based on 3D drawings or samples
• Hardness range: Shore A 30°~80°, with adjustable rebound rate
3. Material Safety and Compliance
• 100% virgin silicone rubber, available in FDA food-grade and UL94 V-0 flame-retardant grades
• Free of phthalates, low VOC content, and certified by RoHS and REACH

Product Detail Description:
• Y-type Structural Design: Featuring a unique dual-lip or triple-lip resilient cross-section, it provides excellent static and dynamic sealing performance, suitable for reciprocating motion shafts, end caps, and waterproof cable entry holes.
• Customizable Irregular Shapes: Not restricted by standard O-ring cross-sections, it can be formed into complex geometric structures such as trapezoidal, grooved, reinforced with skeleton, and multi-hardness co-extrusion.
• Surface Treatment: Default matte surface, with optional smooth molded surface, fine sandblasted finish, or self-lubricating coating to reduce installation friction.
• Reinforcement Options: Aromatic fiber, glass fiber, or metal skeleton can be added according to operating conditions to enhance pressure resistance and extrusion resistance.
Typical Application Scenarios:
• Waterproof sealing of battery packs in new energy vehicles
• Cable penetration sealing for outdoor LED lighting fixtures and ship deck equipment
• Y-rings for industrial valves and pneumatic components
• Sealing of food-grade high-temperature pipelines
• Waterproof gaskets for photovoltaic junction boxes and energy storage devices
