Your Trusted Source for High-Performance Sealing Solutions
As a leading manufacturer and wholesaler of Rubber O-rings, gaskets, seals, sealing rings, we bring industrial-grade reliability to every component—especially this precision-engineered Rectangle Rubber Gasket. Designed for demanding automotive and machine applications, it delivers consistent, leak-proof performance where it matters most.

Engineered for Durability and Fit
This Industrial Rubber Gasket features exact dimensions of 42.1 × 36.1 × 6.0 × 3.0 mm, ensuring a precise fit in flanged housings, sensor mounts, or enclosure joints. Its rectangular cross-section provides greater contact area than standard O-rings, reducing the risk of extrusion and improving sealing under variable pressure. The waterproof design creates a reliable barrier against moisture, dust, and contaminants—critical for under-hood automotive systems or outdoor machinery.

Material Versatility for Every Environment
Available in multiple high-performance elastomers—including EPDM (excellent for weather and steam resistance), Nitrile rubber (NBR) (ideal for oil and fuel exposure), Silicone (for extreme temperatures), and Natural Rubber (NR) (for high elasticity)—each Rubber Seal Ring is selected to match your operational demands. Hardness is customizable across 30–90 Shore A, allowing fine-tuning for soft compression or rigid retention.

Fast, Flexible, and Sample-Ready
We understand the urgency of industrial procurement. That’s why we offer free samples for validation and guarantee a delivery time of just 15 days after order confirmation. Each unit is individually packed in a PE bag to prevent contamination, deformation, or surface damage during transit—ensuring your gaskets arrive production-ready.

Applications Spanning Industries
While optimized for automotive use—such as ECU covers, transmission sensors, and battery trays—this gasket also performs reliably in hydraulic systems, agricultural equipment, and industrial control panels. Its robust sealing capability makes it a go-to choice for engineers prioritizing uptime and environmental protection.
