About Us

Marco Rubber is a Custom O-Ring Manufacturer Committed to Sealing Your Success

Since we were founded in 1980, Marco Rubber & Plastics has been focused on providing successful seals in countless applications for various industries around the world. Our purpose is the same today as it was then: to ensure every seal is a success. After more than 40 years of delivering on that goal, we have become the custom o-ring manufacturer of choice for engineers, purchasing agents, product designers, and more.

Our History

The Marine Aerospace Rubber Company (MARCO) was acquired in 1980 by Leon Belinsky after he’d spent years in the purchasing field without a strong o-ring and seal supplier. The company rebranded as Marco Rubber & Plastic Products, Inc. Initially operating as a distributor for major industry brands, Marco soon branched out on its own to become a truly independent company — growing its supplier network, expanding its specialty products and materials capabilities, and continuing its responsive service for customers.

Leon’s son, Chad, eventually bought the business from his father and oversaw years of continued growth — including developing a strong e-commerce platform and an industry-leading product and material database, buying a larger facility, and eventually branding its own materials. In 2020, Marco Rubber & Plastics completed a deal with Align Capital Partners, enabling the company to accelerate its long-term strategic vision.

Our Commitment to You

As a leading custom o-ring manufacturer, we believe that cheap seals are more costly than application-specific solutions. That’s why we offer far more than catalog and commodity sealing solutions to help you meet your critical goals — we offer decades of application-specific material expertise backed by:

  • The world’s most extensive inventory and production network
  • Industry-leading customer satisfaction and audit scores
  • Fast and easy online ordering and inventory programs

  • A relentless commitment to customer service and support
