Based in Dongguan, Guangdong—China’s premier hub for industrial silicone sealing components—HS specializes in durable silicone O-rings, engineered as waterproof, leak-proof, and corrosion-resistant solutions for plumbing systems, with fully customizable thickness, size, shape, and 20~80 Shore hardness tuning. Our OR-C-03 silicone O-rings are precision-molded from high-grade silicone, with a 500-piece MOQ, full OEM/ODM support, and customer-requested colors to meet the sealing needs of plumbing system manufacturers, contractors, and industrial suppliers worldwide. Whether you require thin silicone O-rings for faucet valves or thick seals for pipe joints, our products combine corrosion resistance, customizability, and long-term durability to eliminate leaks in residential, commercial, and industrial plumbing applications.

Core Features of Our Silicone O-Rings
Our silicone O-rings stand out for their corrosion resistance, waterproof performance, and full customizability—key traits that make them ideal for multi-functional use in plumbing systems of all types.First, corrosion and chemical resistance define our silicone O-rings: Premium silicone resists degradation from common plumbing fluids (tap water, saltwater, cleaning chemicals, and mild acids/alkalis), while remaining impervious to mold and mildew growth in damp plumbing environments. The material also delivers 100% waterproof and leak-proof sealing, even under high water pressure (up to 200 PSI), critical for preventing water damage in residential and commercial plumbing setups.Second, full custom precision is central to our silicone O-rings. Our moulding process achieves a tolerance of ±0.03mm, enabling customizable thickness (from 0.5mm to 10mm), sizes (micro to large diameters), and shapes (standard round, custom irregular profiles) to fit any plumbing component—from faucet cartridges to pipe flanges and water heater valves. With 20~80 Shore hardness tuning, we offer soft O-rings (20~40 Shore) for flexible faucet seals and rigid O-rings (60~80 Shore) for heavy-duty pipe joint sealing.Third, durable plumbing-grade design is embedded in every silicone O-ring. The robust silicone composition resists compression set, temperature fluctuations (-40°C to 230°C), and UV degradation (for outdoor plumbing applications), while maintaining flexibility over years of use—reducing replacement frequency and maintenance costs for plumbing systems.

Competitive Advantages of Our Silicone O-Rings
Choosing our silicone O-rings means partnering with a manufacturer with 20+ years of silicone moulding expertise, prioritizing customizability, reliability, and scalability for plumbing industry clients.
Corrosion Resistance & Rigorous Quality Control
Every silicone O-ring undergoes 100% quality inspection, including corrosion resistance testing (saltwater/chemical immersion), waterproof pressure validation, dimensional precision checks, and hardness calibration (20~80 Shore). Our strict quality control ensures consistent performance across all batches, meeting global plumbing safety standards and eliminating leak risks in residential, commercial, and industrial plumbing systems.
Full Customization Flexibility & Scalable Production
We offer a 500-piece MOQ for silicone O-rings, catering to small plumbing contractors and local manufacturers, while our 10,000-square-meter production facility and automated moulding lines enable bulk orders for major plumbing OEMs. Full OEM/ODM support includes custom thickness, sizes, shapes, hardness levels, colors, and branded logo integration—with free design consultations to optimize O-ring performance for specific plumbing applications.
Cost-Effective Factory-Direct Pricing
As a factory-direct manufacturer, we eliminate middlemen to offer competitive pricing on durable silicone O-rings without compromising corrosion resistance or customizability. Our streamlined production process (from prototyping to mass production) reduces lead times by 20%, ensuring on-time delivery for plumbing system production schedules and bulk replacement part orders.
Technical Expertise & Plumbing Industry Support
Our team of silicone engineering specialists with plumbing system experience provides 24/7 support—from hardness optimization (e.g., 30 Shore for faucets, 70 Shore for pipe joints) to mould design for custom-shaped O-rings. We leverage deep knowledge of plumbing fluid dynamics to refine sealing performance, ensuring optimal leak-proof protection for every application.

Applications of Our Silicone O-Rings
Our versatile silicone O-rings serve critical sealing roles across plumbing systems, thanks to their corrosion resistance and waterproof design:

Residential Faucets & Fixtures: 20~40 Shore silicone O-rings seal faucet cartridges, shower heads, and toilet valves—soft hardness ensures leak-proof sealing with minimal compression, while corrosion resistance prevents degradation from tap water minerals.
Commercial Plumbing Pipes: 60~80 Shore silicone O-rings seal pipe joints and flanges in commercial buildings—rigid hardness withstands high water pressure, corrosion resistance protects against chemical cleaners, and custom thickness fits standard pipe sizes.
Water Heaters & Boilers: Custom-thickness silicone O-rings seal pressure relief valves and inlet/outlet ports—temperature stability resists hot water heat (up to 230°C), while leak-proof design prevents dangerous pressure leaks.
Industrial Plumbing Systems: Corrosion-resistant silicone O-rings seal chemical transfer pipes and wastewater systems—resistance to mild acids/alkalis protects against degradation, and custom shapes fit non-standard industrial plumbing components.
Outdoor Plumbing Fixtures: UV-resistant silicone O-rings seal garden hose connectors and outdoor spigots—corrosion resistance withstands weather exposure, waterproof design prevents outdoor leaks, and durability suits year-round use.

At our Dongguan manufacturing facility, we leverage advanced moulding technology and a skilled workforce (100+ professionals) to produce silicone O-rings that exceed plumbing industry standards. Our commitment to sustainability is reflected in eco-friendly production practices (recyclable silicone scrap, low-waste moulding) without compromising performance. We back all silicone O-rings with a 3-year warranty against manufacturing defects, and offer lifetime technical support for custom plumbing seal designs. Whether you need thin O-rings for faucets or thick seals for pipe joints, we deliver silicone O-rings that combine reliability, customizability, and value—engineered for plumbing, built to seal.
