Reflecting on a Milestone Year 2025 was a big year for Marco Rubber & Plastics. We welcomed new leadership, added Colonial Seal Company to the Marco Group, expanded our in-stock inventory, and implemented meaningful price reductions across key materials. Each change strengthened how we serve our customers, allowing us to offer faster quotes, more availability, […]
The oil and gas industry constantly pushes seal materials to their limits with high-pressure gas systems. Every cycle adds mechanical and thermal stress. Rapid decompression can pull trapped gas through the seal body, forming cracks that grow until the part fails. Joint seams and poor vulcanization only accelerate the problem. The Challenge A leading manufacturer […]
Seals face constant exposure to heat, pressure, and aggressive fluids in chemical processing. Standard elastomers can swell, crack, or lose strength, leading to leaks and unplanned downtime. Markez® FFKM compounds from Marco Rubber & Plastics are engineered to perform under these conditions. They deliver broad chemical compatibility and thermal stability up to 600°F, offering the […]
Medical device performance depends on consistent and reliable sealing. A small variation in o-ring size or tolerance can cause leaks, assembly issues, or premature wear. After o-rings in a clamp system began failing early, a medical device manufacturer reached out to Marco Rubber & Plastics. The parts met spec but created too much compression during […]
Aerospace manufacturing demands sealing precision. Every o-ring must perform flawlessly under pressure, temperature, and chemical exposure. Even a minor fit or compression issue can cause leaks, contamination, and costly production delays. After repeated seal failures in a critical pump assembly, a leading aerospace manufacturer reached out to Marco for help with identifying the cause and […]
In food processing, seals do more than contain pressure. They protect product quality and keep systems compliant. When o-rings in a pressure vessel began extruding from their grooves, one manufacturer turned to Marco Rubber & Plastics for help resolving the contamination risks and unplanned shutdowns. The Challenge A major food processor was experiencing seal failures […]
Cutting and Sourcing Custom Gaskets: A Complete Guide When you’ve got your gasket specs in hand, it may feel like the hardest part is behind you. But many buyers discover this is when the real challenge begins: getting the gasket made correctly and delivered on time. Unlike o-rings, gaskets rarely come off the shelf. In […]
Choosing the right O-ring material is critical to the performance and reliability of your equipment. While silicone is a type of rubber, or synthetic elastomer to be precise, silicone has distinct properties making it suitable for certain applications. Meanwhile, other rubbers may be a better option for different situations. Selecting the wrong one can lead […]
It can be a common point of confusion in engineering and design: O-rings, gaskets, and seals. While all of these components are designed to prevent leaks, their fundamental design, function, and ideal applications are very different. Making the right choice between them is crucial for your equipment’s performance, long-term reliability, and avoiding costly downtime. This […]
Hydraulic seals are the unsung heroes of countless industrial systems. While often overlooked, they play a critical role in converting fluid power into linear motion, ensuring the efficiency and reliability of your equipment. A seal failure can bring an entire operation to a halt, which is why choosing the right solution is essential for performance […]
