Based in Dongguan, Guangdong—China’s premier hub for food-grade rubber component manufacturing—HS specializes in custom-sized food-grade silicone sealing rings, engineered as non-toxic, odorless, and hygienic leak-proof seals for food processing machinery and industrial machinery applications. Our EE-917-C3 silicone rubber gasket seals (also referred to as silicone rubber seals) are precision-crafted via moulding processing to meet the strict safety and performance standards of the food industry, combining high-temperature resistance, full customization, and food-grade compliance to deliver reliable machinery accessory solutions for food processing manufacturers worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke custom-sized sealing rings for food processing equipment, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your food processing sealing needs.
Core Features of Our Silicone Rubber Sealing Rings Our silicone rubber sealing rings and silicone rubber seals stand out for their food-grade compliance, hygienic design, and leak-proof performance—key traits that make them ideal for food processing machinery and industrial machinery accessories.First, the material quality of our silicone rubber sealing rings is unmatched. We utilize premium food-grade silicone rubber (supplemented with EPDM, NBR, and NR options) that is non-toxic, odorless, and compliant with global food safety standards (FDA, LFGB), ensuring silicone rubber seals are safe for direct contact with food and food processing fluids. This formulation also offers exceptional high-temperature resistance (withstanding up to 250°C), maintaining structural integrity in the heat of food cooking, baking, and sterilization equipment while delivering leak-proof sealing performance.Second, custom-sized precision defines our silicone rubber sealing rings. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber seals create airtight, hygienic seals for food processing machinery components—from mixing tank lids to conveyor belt joints. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber sealing rings with food processing brand identity without compromising hygiene or functionality.Third, durability is embedded in every silicone rubber sealing ring we produce. The non-porous silicone surface resists bacterial growth, is easy to clean and sanitize, and resists wear from food particles and cleaning chemicals—extending the service life of food processing machinery accessories and reducing maintenance costs for manufacturers.
Competitive Advantages of Our Silicone Rubber Sealing Rings Choosing our silicone rubber sealing rings and silicone rubber seals means partnering with a manufacturer with 20+ years of rubber processing expertise, prioritizing food safety, customization, and customer-centric service for food processing and industrial applications. Food-Grade Compliance & Rigorous Quality Control Every silicone rubber sealing ring undergoes 100% quality inspection before shipment, including food-grade safety validation, high-temperature resistance testing, leak-proof performance checks, and dimensional verification—ensuring zero defects and adherence to global food processing standards. Our strict quality control processes guarantee silicone rubber seals meet the hygiene and durability benchmarks required for food processing machinery and industrial equipment. Custom-Sized Flexibility & Scalable Production We offer a MOQ of 500 pieces for silicone rubber sealing rings, making our solutions accessible to small and medium-sized food processing manufacturers, while our 10,000-square-meter production facility and 2000+ existing molds enable scalable production to meet bulk orders for major industrial machinery brands. Custom sizes, shapes, and material blends (silicone/EPDM/NBR/NR) for silicone rubber seals are available to fit any food processing machinery component or industrial machinery accessory. Cost-Effective Factory-Direct Pricing As a direct manufacturer, we eliminate middleman markups, offering competitive pricing on food-grade silicone rubber sealing rings without compromising non-toxic, odorless, or leak-proof performance. Our one-stop procurement service streamlines design, prototyping, and production, reducing lead times and supply chain costs for your food processing and industrial machinery component orders. Technical Expertise & 24/7 Support Our team of food-grade rubber engineering specialists provides 7×24 online support for silicone rubber sealing ring inquiries, offering guidance on material selection and seal design optimization for food processing machinery. We leverage deep food industry knowledge to solve complex sealing challenges, ensuring silicone rubber seals deliver optimal hygienic and leak-proof performance in food processing environments.
Applications of Our Silicone Rubber Sealing Rings Our versatile silicone rubber sealing rings and silicone rubber seals serve critical sealing roles in food processing and industrial settings, thanks to their food-grade compliance, high-temperature resistance, and leak-proof design:
Food Mixing & Blending Equipment: Silicone rubber sealing rings seal mixing tanks and blender lids—their non-toxic, odorless composition prevents contamination of food ingredients, while leak-proof design stops spills during high-speed mixing. Baking & Cooking Machinery: Custom-sized silicone rubber seals fit oven doors and fryer lids in commercial food processing facilities—their high-temperature resistance withstands baking/cooking heat, and hygienic surface is easy to sanitize between production runs. Food Packaging Machinery: Silicone rubber sealing rings act as machinery accessories for packaging equipment—their leak-proof performance ensures airtight seals for vacuum-packed foods, and food-grade compliance meets safety standards for packaged goods. Dairy & Beverage Processing: EPDM-blended silicone rubber seals are adapted for milk processing tanks and beverage filling lines—their non-toxic formulation is safe for dairy and beverage contact, and leak-proof design prevents product waste. Industrial Food Storage Equipment: Silicone rubber sealing rings seal food storage silos and transport containers—their hygienic design resists mold and bacterial growth, while high-temperature resistance withstands pasteurization processes for stored food products.
At our Dongguan manufacturing facility, we leverage a team of over 100 skilled professionals and state-of-the-art moulding processing equipment to produce silicone rubber sealing rings that exceed industry standards. Our commitment to quality is backed by ISO 9001 and ISO 14001 certifications, validating the safety and sustainability of our silicone rubber seals for international food processing and industrial markets. We back all silicone rubber sealing rings with a 3-year warranty: if unused silicone rubber seals develop quality issues within this period, we offer free returns and replacements. Whether you need custom-sized food-grade silicone sealing rings for mixing tanks or leak-proof seals for industrial food processing machinery, we deliver silicone rubber seals that combine safety, performance, and value—engineered for food processing, built to seal.
