Description
Product Overview
The XBVV 419 piece Universal Metric O Ring Kit is engineered to meet the diverse sealing needs of professionals and DIY enthusiasts alike. Containing 32 carefully selected NBR O‑rings that span from 3 mm to 34 mm, the kit covers the most frequently used metric dimensions across a wide range of industries. Each ring is precision‑molded to exact tolerances, guaranteeing a snug fit that eliminates leakage and reduces wear on mating components.
Commercial‑grade NBR (nitrile butadiene rubber) forms the core material of every O‑ring in this collection. NBR offers exceptional resistance to oil, fuel, and a broad temperature spectrum ranging from -40 °F to 248 °F. This durability ensures that the rings maintain their elasticity and sealing performance even under harsh chemical exposure or extreme thermal cycling, making them ideal for automotive engines, hydraulic systems, and pneumatic equipment.
The kit arrives in a robust, reusable plastic storage box designed for durability and organization. Each size is clearly labeled on a durable sheet that fits inside the box, allowing users to locate the required O‑ring within seconds. The box’s snap‑fit lid protects the rings from dust, moisture, and mechanical damage, extending the lifespan of the components and simplifying inventory management for workshops and service bays.
Usage
Whether you are repairing a leaking faucet, maintaining a pressure washer pump, or servicing a pneumatic valve on an industrial machine, this universal metric O‑ring kit provides the exact size you need without the hassle of searching multiple suppliers. The broad size range makes it suitable for sealing applications in automotive cooling systems, fuel lines, brake circuits, and even marine engine components where corrosion resistance is critical.
In addition to traditional fluid sealing, the kit excels in applications that demand vibration damping and shock absorption. The flexible NBR material absorbs minor movements between mating parts, reducing the risk of metal‑to‑metal contact and extending the service life of both the O‑ring and the equipment it protects. Technicians often rely on this kit for quick field repairs, as the clear labeling and organized storage enable rapid identification and installation.
For hobbyists and makers, the kit serves as a versatile inventory of components for custom projects involving robotics, 3D‑printed assemblies, and experimental fluid circuits. Its compact packaging makes it easy to transport to job sites, workshops, or even outdoor locations where on‑the‑spot sealing solutions are required.

FAQ
What material are the O‑rings made from?
All O‑rings in this kit are made from commercial‑grade NBR (nitrile butadiene rubber), which provides excellent resistance to oil, fuel, and a temperature range from -40 °F to 248 °F.
Can I use these O‑rings for high‑pressure hydraulic systems?
Yes, the NBR material and precise tolerances make the rings suitable for many high‑pressure applications, though for extremely high pressures you may consider a specialized material such as Viton.
How are the sizes organized inside the box?
Each size is listed on a printed sheet that sits inside the box, and the O‑rings are arranged sequentially from smallest to largest, allowing quick retrieval without the need for additional tools.
Do you offer a replacement if a size is missing?
Absolutely. If any size is missing or damaged, contact XBVV customer service with your order details, and we will provide a replacement at no extra cost.
Is this kit suitable for marine environments?
The NBR material offers good resistance to water and mild corrosion, making it appropriate for many marine sealing tasks, though for prolonged exposure to saltwater, a marine‑grade material may be preferred.
