NBRINGO O-Ring Assortment Kit 826-Piece SAE & Metric — Buna-N Nitrile, Organized Cases

NBRINGO 826-piece O-ring assortment delivers both SAE and metric nitrile seals in a single, organized kit with pick tools for quick repairs and maintenance.

This comprehensive set groups 32 SAE sizes and 32 metric sizes of nitrile (Buna-N 70A) O-rings into clear, compartmentalized cases and includes four pick & hook tools so you can identify, select, and replace seals fast. The rings are made for general-purpose sealing where oil, fuel, and hydraulic compatibility are required; each piece is arranged for quick visual matching and long-term storage. Whether you’re a technician, hobbyist, or homeowner, the kit reduces downtime by keeping the right size on hand for most common fittings and valves.

Which sizes and standards are included, and how are they organized?

The kit contains two complete sets: 32 SAE standard sizes plus 32 metric standard sizes, totaling 826 pieces across the assortment. Sizes are separated into labeled compartments inside durable transparent cases so you can quickly locate the exact diameter you need.

• 32 SAE sizes and 32 metric sizes for broad coverage
• 826 total O-rings, with counts per size for repeated use
• Two clear, compartmentalized cases for instant identification
• Labeling and layout designed for quick visual selection

What material are the O-rings made of, and what environments do they suit?

The O-rings are manufactured from commercial-grade Nitrile rubber (Buna-N 70A), chosen for its strength, abrasion resistance, and compatibility with many oils and fuels. They hold shape under pressure and perform well in common automotive, industrial, and home repair scenarios.

• Buna-N 70A nitrile compound for oil and fuel resistance
• Good abrasion and compression set resistance for longevity
• Suitable for hydraulic fittings, pumps, valves, and engines
• Not for prolonged high-temperature or aggressive chemical use without verification

How will this kit speed up repairs and maintenance tasks?

The assortment minimizes trips to the store by offering immediate access to common O-ring sizes and includes four pick & hook tools to remove and fit seals without damage. Having a labeled case and burr-free finishes reduces installation time and improves first-time-fit success.

• Instant size matching from the organized case layout
• Included pick & hook tools for safe removal and installation
• Burr-free finish lowers risk of leaks and extends part life
• Compact cases store easily in a toolbox or cabinet

What should I check before using these O-rings in my equipment?

Always confirm the required inner diameter and cross-section before installing a replacement O-ring, and verify material compatibility with the fluids and temperatures in your application. Use the included tools to avoid nicking or stretching rings during installation.

• Measure ID and cross-section to ensure correct fitment
• Confirm Buna-N compatibility with your fluids and temps
• Use supplied pick tools to prevent damage during change-out
• Keep spare sizes organized to speed future repairs

Who is this for: The NBRINGO 826-piece SAE & Metric O-ring Kit is aimed at mechanics, maintenance technicians, plumbers, marine and RV owners, DIY enthusiasts, and facilities staff who need a broad, ready-to-use selection of nitrile seals.
