Washer
Categories : Maintenance & Lubrication
High-Performance Alternative to Standard O-Rings Our precision-engineered rubber washers—also known as square-cuts, lathe-cuts, or square-rings—feature a rectangular cross-section designed for superior sealing integrity. While they follow the AS 568 size standards and groove designs, their geometry offers enhanced stability and longevity compared to traditional O-Rings, making them the ideal choice for high-pressure and critical applications. Why Choose Rubber Washers? While O-Rings are versatile, Rubber Washers provide distinct mechanical advantages in specific environments: Superior Pressure Resistance: The rectangular profile handles higher pressure loads without extrusion. Enhanced Stability: Higher groove-fill rate prevents the seal from sliding, twisting, or spiraling during operation. Precision Engineering: Mold parting lines can be strategically placed away from sealing surfaces, ensuring a burr-free finish and tighter dimensional tolerances. Versatile Motion: While primarily used for static seals, they are highly effective for piston and rod seals.
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.
Bonded seal
A bonded seal is a hybrid sealing component that combines a metal washer with an elastomeric sealing ring bonded to its inner diameter. This design creates a reliable, leak-proof seal around bolts, screws, and flanged connections in static applications such as hydraulic and pneumatic systems. Originally developed by the Dowty Group, these seals are also commonly known as Dowty seals or bonded washers.
