Engineered for Extreme Temperatures and Long-Term Durability DIAO silicone raw material stays flexible and stable from -60°C to 250°C without chalking, cracking, deforming, or becoming sticky. It is built for industries where heat, pressure, and continuous operation are the norm—bag-making machines, heat-press systems, automotive engine compartments, high-temperature exhaust systems, and industrial cooling environments. Fewer failures mean fewer shutdowns and lower maintenance costs.
Reinforced with International-Grade Formulation for Superior Strength Using top-tier base polymers combined with high-dispersion reinforcing systems, DIAO silicone raw material delivers stronger tear resistance, higher elongation, outstanding tensile strength, and excellent compression set performance. Silicone sheets stay firm under pressure. Silicone hoses bend repeatedly without cracking. Cooling silicone tubes remain flexible even after long-term heat exposure. This is durability engineered for real industrial demand.
Flexible Customization for All Vehicle Types and Modifications Inner diameter, outer diameter, wall thickness, color, and shape — everything can be customized. These products are widely used in racing cars, commercial vehicles, buses, and heavy machinery.
Full-Scale Quality Control with Multi-Layer Testing From raw material mixing to vulcanization and final inspection, every stage is strictly monitored. Each hose undergoes pressure testing, dimensional inspection, and high-temperature aging tests to ensure flawlessness and compliance.
Clean Finish and Smooth Surface — Ideal for OEM and Aftermarket The surface of each hose is clean and glossy, with options for shiny or fabric-textured finishes. Free from defects or bubbles, they are ideal for brand presentation and customization.
Thanks to precise craftsmanship and full-process quality control, DIAO silicone hose not only meets the stringent standards of OEM manufacturers but also wins the trust of automotive tuners and aftermarket clients around the world — making it a dependable long-term partner in the silicone hose industry.
Withstands High Temperatures Designed for engine bays, silicone hoses resist temperatures over 120°C (up to 200°C for some models), maintaining flexibility and sealing even under extreme heat. Handles High Boost Pressure Reinforced with multiple layers of fiber braid, these hoses can handle strong positive and negative pressure—ideal for turbochargers, intake systems, and radiator lines.
Flexible & Easy to Install Silicone is softer than metal or rigid plastic. It bends easily to fit tight corners and awkward angles in your engine bay, making installation simple and tool-friendly. Reduces Vibration & Noise The elastic material helps absorb engine vibration and reduces noise transfer—great for both comfort and component protection.
Silicone tubing should not be stored in direct sunlight or high-temperature environments. Ultraviolet rays and prolonged heat exposure can break down the silicone’s molecular structure, causing yellowing, hardening, or cracking. It is recommended to store the tubing in a cool, well-ventilated indoor space, away from heat sources and lighting fixtures.
Our factory specializes in the production and supply of high quality silicone hoses, food grade silicone hoses, medical silicone hoses, fuel hoses, radiator hoses, air rubber hoses, EPDM sealing strips, spiral protective covers and silicone plates and other trucks, automotive rubber accessories (support OEM and ODM).
