About Our Product
- Oil-Resistant Specialized Rubber Formula
NBR rubber features a customized molecular structure that resists swelling and degradation when exposed to various petroleum-based media. It maintains stable physical properties in long-term contact with engine oil, hydraulic oil, gear oil, and grease, avoiding volume change or sealing failure caused by medium erosion.
- Excellent Pressure-Bearing & Structural Stability
Designed for continuous pressure working conditions, NBR O-rings possess strong structural rigidity and stable elasticity. They withstand frequent hydraulic pressure impact and long-term extrusion, maintaining an intact sealing structure without deformation or relaxation under rated working pressure.
- Superior Dynamic Friction Adaptability
With balanced hardness and wear resistance, NBR seals adapt well to reciprocating and rotating dynamic sealing scenarios. They resist friction loss and surface abrasion during mechanical movement, effectively extending service life for moving assembly parts.
- Reliable Low-Temperature Working Performance
This rubber material retains good flexibility and sealing toughness in low-temperature industrial environments. It is less prone to embrittlement and cracking compared with other common rubber materials, ensuring stable operation in cold workshops and low-pressure equipment systems.
- Fine Airtightness & Hydraulic Sealing Effect
Uniform vulcanization structure provides excellent compactness and fitting performance. NBR O-rings achieve stable airtight and liquid-tight sealing effects, effectively preventing medium leakage in hydraulic circuits, pipeline joints, and mechanical assembly gaps.
- High Cost-Efficiency & Industrial Compatibility
As a mature general-purpose sealing material, NBR balances performance and economic value perfectly. It is highly compatible with most industrial mechanical structures, requiring no complex matching conditions, ideal for large-scale industrial assembly and mass application.
- Consistent Batch Quality & Precision Processing
Manufactured with standardized vulcanization and precision trimming technology. Each O-ring features accurate dimension tolerance, uniform roundness, and a smooth surface. Stable batch consistency guarantees interchangeability for equipment assembly and replacement.
- Diversified Specifications & Application Coverage
Widely applicable for hydraulic systems, pneumatic tools, automotive accessories, general machinery, household equipment, and industrial transmission devices. Complete standard size ranges are available, along with customized non-standard specifications for special mechanical structures.

FAQ
Q: Are you a manufacturer or a trading company?
A: We are a manufacturer.
Q: How to get the quickest quotation?
A: Send an email with the drawing directly.
Q: How to get a quotation without a drawing?
A: You can send a sample, pictures, or detailed descriptions of products to us; we will return a drawing for confirmation.
Q: I have an idea for a new product, but not sure if it can be manufactured. Can you help?
A. Yes! We are always happy to work with potential customers to evaluate the technical feasibility of your idea or design, and we can advise on materials, tooling, and likely set-up costs.
Q: My custom products have already been developed on CAD. Can you use the drawings?
A. Yes! DWG, DXF, IGES, Solidworks and Rhino files can all be used to generate quotes, models and mould tools - this can save time and money in producing your parts.
Q: Can I test my idea/product before committing to mould tool manufacture?
A. Yes, we can use CAD drawings to make models for design and functional evaluations.
Q: What type of plastic material is best for my design/product?
A. Materials selection depends on the application of your design and the environment in which it will function. We will be happy to discuss the alternatives and suggest the best material.
Q: How about samples?
A: Free samples are available for your quality evaluation, but you should pay the freight. Regarding customized products, sample and mould orders will go first before mass production.
