Our Heavy-Duty Rectangular Rubber Sealing Rings (also known as Square-Cut Gaskets or Flat Sealing Washers) are high-performance elastomeric seals designed for large-diameter pipelines, industrial flanges, manholes, and heavy storage vessels. Unlike standard O-rings, their flat, rectangular cross-section provides a larger sealing surface area, ensuring a tight, leak-proof barrier under high compression and bolt load.
Molded from premium industrial-grade rubber, these gaskets offer exceptional resilience, sealing reliability, and resistance to environmental degradation, making them ideal for both fluid and gas containment.
■ Key Features & Benefits
- Maximum Sealing Surface: The rectangular/square cross-section maximizes the contact area between mating surfaces, providing superior sealing performance even at lower tightening torques.
- Excellent Compression Set Resistance: Formulated to maintain elasticity and memory under long-term compression, preventing leaks caused by joint relaxation.
- High Tensile Strength & Durability: Heavy-duty construction resists tearing, extrusion, and physical wear during installation and operation.
- Superb Media Resistance: Available in multiple rubber compounds to withstand water, sewage, industrial oils, chemicals, ozone, and extreme weather.
- Precision Molded: Manufactured with strict dimensional tolerances to ensure a perfect, flush fit into flange grooves or flat-face joints.
■ Technical Specifications
- Material: NBR (Nitrile), EPDM, Neoprene (CR), Natural Rubber (NR), or Viton (FKM) depending on application.
- Cross-Section Profile: Rectangular / Square Cut.
- Hardness Range: 60 to 80 Shore A (Customizable).
- Size Range: Custom large diameters, inner/outer diameters (ID/OD), and thicknesses tailored to specific standards (ANSI, DIN, JIS) or drawings.
- Applications: Water supply and drainage systems, pipe jacking joints, industrial tanks, marine equipment, HVAC, and chemical processing pipelines.
■ OEM & Custom Manufacturing
We specialize in producing custom-sized large rubber gaskets to meet your precise engineering requirements. Whether you need a specific rubber compound for chemical compatibility or custom dimensions for specialized machinery, we provide high-quality B2B manufacturing solutions with fast turnaround times.
- Maximum Sealing Surface: The rectangular/square cross-section maximizes the contact area between mating surfaces, providing superior sealing performance even at lower tightening torques.
