Item No. RGS-019
Rubber O-rings serve as critical sealing components for pipe, valve, and pump connections across diverse industrial systems. These precision-molded rings seat neatly into grooves and glands, forming a reliable barrier against liquid and gas leakage under varying working pressure — no on-site cutting, punching, or additional sealing compounds required.
Manufactured from high-quality synthetic rubber including NBR, EPDM, Neoprene CR, and FKM fluoro-rubber, they deliver dependable sealing performance across a wide range of media and temperatures. With good elasticity, excellent compression-set resistance, and superior anti-aging properties, the O-rings compensate for minor surface irregularities in mating grooves to maintain a tight, long-lasting seal.
Precision-molded dimensions – consistent cross-section and inner diameter
Multiple material options – NBR, EPDM, Neoprene CR, FKM (Viton®)
Excellent compression-set resistance – maintains sealing force over time
Superior anti-aging properties – resists oxidation, ozone, and UV degradation
Good elasticity – conforms to groove irregularities for a tight seal
Reliable under varying pressure – suitable for vacuum to high-pressure systems
Wide temperature range – material-dependent performance
Chemical resistance – grade-dependent resistance to oils, water, and weak chemicals
Easy installation – seats directly into standard grooves and glands
Fully customizable – sizes, cross-sections, hardness, and materials to your specifications
Reliable Leak Protection – Precision-molded O-rings compress evenly within the groove, creating a consistent, leak-tight seal against liquids and gases.
Excellent Compression-Set Resistance – Maintains sealing force over extended periods, reducing re-torquing, maintenance frequency, and unplanned downtime.
Superior Anti-Aging Performance – Resists oxidation, ozone, UV, and weathering, ensuring long service life even in harsh outdoor or industrial environments.
Wide Material Selection – NBR for oils and fuels, EPDM for water and steam, Neoprene for moderate chemical exposure, and FKM for aggressive chemicals and high temperatures.
Plumbing & water systems – pipe joints, faucets, valves, fittings
Water treatment – pumps, filtration units, dosing equipment
Petrochemical – valves, flanges, pumps, instrumentation
General mechanical equipment – hydraulic and pneumatic components
HVAC systems – refrigerant lines, compressors, valve connections
Automotive – engine components, fuel systems, cooling systems

Size
OEM sizes according to customer’s requirement.
Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
What materials are available for rubber O-rings?
We offer NBR, EPDM, Neoprene (CR), FKM (Viton®), silicone, and custom compounds to suit different media, temperatures, and environmental conditions.
Which material should I choose for my application?
NBR is ideal for oils and fuels, EPDM for water and steam, Neoprene for moderate chemical exposure, and FKM for aggressive chemicals and high temperatures. Contact our team for specific recommendations.
What is the typical hardness range?
Our O-rings range from 50 to 90 Shore A. Lower hardness offers better conformity; higher hardness provides greater extrusion resistance under pressure.
What temperature range can rubber O-rings withstand?
Depending on material: NBR (-30°C to +110°C), EPDM (-50°C to +150°C), Neoprene (-35°C to +100°C), FKM (-20°C to +230°C), Silicone (-60°C to +230°C).
Are these O-rings suitable for high-pressure applications?
Yes, with appropriate hardness, cross-section, and groove design. Please consult our team for specific pressure requirements.
Can these O-rings be used in potable water systems?
Yes. EPDM and food-grade compounds are available for potable water and food processing applications.
Do you offer standard and custom sizes?
Yes. We stock common metric and imperial sizes and manufacture custom O-rings to your drawings or samples.
What quality standards do you meet?
All products are manufactured under ISO 9001 quality management systems. Material certifications and test reports are available upon request.
