U-Cup
Categories : Rubber Products & Parts
U-Cups (U-rings) are versatile lip seals, named after their characteristic "U"-shaped cross-section. They are specifically engineered for reciprocating applications and serve as primary seals in hydraulic and pneumatic cylinders. Key Performance Benefits Pressure-Energized Sealing: The U-shape enables the sealing lips to expand against the hardware surface under system pressure. As the pressure increases, the sealing force proportionally grows, ensuring a reliable seal. Dual-Purpose Design: U-Cups function effectively as Rod Seals (preventing external leakage) and Piston Seals (preventing internal bypass between cylinder chambers). Optimized Friction: The lip geometry provides a secure seal with minimal contact area, reducing heat generation and mechanical wear during operation. Synergy with Back-up Rings High-Pressure Integrity: For systems operating above 5 MPa (50 bar), pairing a U-Cup with a back-up ring is essential to prevent material extrusion into clearance gaps. Structural Support: The back-up ring stabilizes the U-Cup in dynamic applications, particularly when large extrusion gaps or high-speed cycles are present. Common Industry Materials Polyurethane (PU): Offers superior abrasion resistance and high shear strength, ideal for heavy-duty hydraulic systems. Nitrile (NBR): Standard choice for pneumatic cylinders and lower-pressure environments. PTFE / POM: Often used for back-up rings to provide high-hardness support.
Rubber Grommet
Categories : Maintenance & Lubrication
Rubber Grommet High-performance sealing for protection and insulation A Rubber Grommet is an essential component designed to protect wires, cables, and tubing as they pass through panel holes. By eliminating sharp edges and absorbing mechanical vibrations, it prevents insulation damage and ensures the long-term integrity of your electrical and fluid systems. Materials & Applications Engineered to meet the rigorous demands of the automotive, electrical, construction, and manufacturing industries. Available in: NBR EPDM Silicone FKM
Rubber Cord
A rubber cord is a solid, round elastomer profile manufactured through a high-precision extrusion process. Unlike molded O-rings with fixed sizes, rubber cords are supplied as continuous stock, allowing for the creation of seals in virtually any circumference. When to Use Rubber Cord: Non-Standard Sizes: Ideal when standard O-ring sizes are unavailable. Large Diameter Seals: Perfect for sealing large tanks, lids, or industrial housings. Rapid Maintenance: Facilitates immediate on-site repair and replacement, minimizing downtime. Prototyping: A cost-effective solution to test custom sealing designs before investing in molds.
O-Ring
Categories : Industrial Parts & Safety Gear
O-Ring seals are used to prevent the leakage of liquids or gases and are widely applied in industrial settings. They have many key features and advantages: Wide Range of Applications: Excellent adaptability allows reliable sealing solutions under a broad range of pressures, temperatures, and tolerance conditions. Easy Installation and Maintenance: Simple design, no need to apply sealant or perform secondary tightening during installation, greatly simplifying maintenance. No Precise Torque Required: Installation does not require specific torque, reducing the risk of damage from over-tightening. Lightweight and Space-Saving: Compact and lightweight, helping users maximize available space. Reusability: In many applications, O-Rings can be reused, providing advantages over other sealing options. Predictable Lifespan: Under proper conditions, the product's lifespan corresponds to the natural aging cycle of the rubber material, making it easier to predict. Failure Modes Are Easy to Identify: O-Ring failures are typically gradual, facilitating detection and preventive maintenance. Stable Sealing Performance: O-Ring design allows direct contact with metal parts, with sealing efficiency unaffected by minor compression variations. Cost-Effective: Simple structure and high production efficiency make O-Rings an economical yet high-performance sealing choice.

Nitrile Rubber(NBR)
Categories : Rubbers / Synthetic Rubbers
Nitrile Rubber(NBR) is an unsaturated rubber made from the copolymerisation of butadiene (BD) and acrylonitrile (ACN), which is usually known by several names, such as Bunan, NBR, etc. The content of acrylonitrile (ACN) determines the key properties of NBR, which provides different degrees of oil resistance and low temperature resistance. The content of acrylonitrile (ACN) determines the key performance of NBR, providing different degrees of oil resistance and low temperature resistance, so NBR is also the most commonly used oil resistant rubber.
