OneMonroe’s Metric Buna O-Rings are engineered to provide reliable sealing performance across a variety of industrial and commercial applications. Made from high-quality Buna-N (Nitrile) rubber, these O-rings are known for their excellent resistance to oils, fuels, and other petroleum-based products, making them ideal for use in environments where durable, leak-proof seals are essential. Buna-N’s resilient properties allow it to maintain its integrity even in challenging temperatures, ranging from -40°F to 250°F, ensuring these O-rings can withstand both low and high-stress conditions with ease. With a broad range of metric sizes available, OneMonroe ensures you’ll find the right fit for your exact specifications.
Our Metric Buna O-Rings are crafted to offer outstanding resistance to abrasion and tearing, providing long-lasting performance in rigorous applications. This makes them well-suited for automotive, aerospace, marine, and hydraulic systems, as well as in general maintenance and repair settings. The unique chemical composition of Buna-N allows these O-rings to endure pressure and friction over extended periods without compromising their sealing capabilities, making them a reliable choice for static and dynamic sealing tasks. Each O-ring is manufactured to precise industry standards, ensuring a dependable fit and function in every installation.
