NBRINGO's 1540-piece O-ring assortment delivers a wide selection of 32 metric sizes in resilient nitrile rubber, stored in a clear compartmentalized case and paired with four pick-and-hook tools for fast, accurate seal replacement.

Whether you maintain pressure washers, fix plumbing leaks, service vehicles, or keep workshop equipment running, having the right O-ring on hand saves time and prevents component damage. This kit consolidates a broad range of commonly used metric diameters into one portable box, helping you identify, match and install replacement seals without a trip to the parts store.

Which sizes and quantities are included in the kit?

The set contains 1540 O-rings across 32 metric sizes, designed to cover frequent repair needs for small to medium fittings and assemblies. Sizes are organized in clearly labeled compartments so you can find matches quickly.

• 32 distinct metric sizes, from small sealing rings to larger diameters for plumbing and pump fittings.
• Uniform black nitrile color for easy visual comparison and compatibility with many oil and water applications.
• 1540 total pieces to keep multiple spares on hand and reduce repeat reordering.

How durable are the O-rings and what materials are used?

All rings are molded from nitrile (NBR), a synthetic rubber known for its oil and abrasion resistance, making them suitable for many mechanical and fluid systems. They retain shape under compression and offer reliable sealing in common workshop environments.

• Nitrile rubber construction resists oils, greases and everyday wear.
• Flexible and resilient enough for repeated assembly cycles without tearing.
• Consistent molding reduces variability and improves sealing predictability.

What tools and organization features come with the kit?

The kit includes four metal pick-and-hook tools that speed removal and installation of rings from grooves and housings without damaging surrounding parts. A rigid, transparent plastic case with individual compartments keeps sizes separated and visible so you can inventory quickly.

• Four ergonomically shaped pick/hook tools for safe, precise removal and placement.
• Clear, compartmentalized storage box with removable trays for mobile workspace use.
• Labels or printed size indicators on compartments to cut search time during repairs.

Where can I use these O-rings safely and effectively?

These nitrile O-rings are suitable for many non-specialized applications including automotive, plumbing, pumps, garden equipment and general industrial maintenance. They are not intended for extreme chemical exposure or high-temperature specialty uses unless verified against material compatibility charts.

• Automotive seals, fuel and oil lines (verify compatibility for fuel additives).
• Household plumbing fixtures, valves and hose fittings.
• Workshop tools, garden equipment, pressure washers and light industrial hardware.

Who is this for: This NBRINGO assortment is built for DIYers, mechanics, maintenance technicians and facility managers who need a broad, ready-to-use selection of metric O-rings. If you perform routine repairs on vehicles, pumps, valves or household systems and prefer to diagnose and replace seals yourself, this kit reduces downtime and avoids emergency parts runs. For specialized chemical or extreme temperature service, confirm nitrile compatibility before deploying.
