NBRINGO O-Ring Assortment Kit 1086-Piece — 32 SAE Sizes Buna-N with 4 Pick & Hook Tools

NBRINGO's 1086-piece O-ring assortment is a comprehensive SAE-compliant Buna‑N kit that supplies 32 sizes and four pick-and-hook tools for reliable, leak-resistant sealing in hydraulic, automotive, plumbing, and general repairs.

This kit gathers a wide range of commonly used AS568 O-ring sizes in one clear, durable organizer so you can quickly find the right seal when a routine fix turns urgent. The nitrile rubber (Buna‑N) compound balances oil resistance and resilience, and the compact case keeps parts separated for fast identification on the workbench or in the field. It’s designed for technicians, hobbyists, and homeowners who prefer to carry a full complement of replacement seals without buying individual rings every time a leak appears.

Which applications will these Buna‑N O‑rings work best for?

These O-rings suit many mechanical and fluid systems where nitrile’s oil and fuel resistance is beneficial. They’re commonly used in automotive connectors, hydraulic fittings, pumps, valves, and household appliances. Avoid high-temperature or aggressive chemical environments where nitrile is not recommended.

• Hydraulic fittings and pneumatic connections where oil resistance matters
• Automotive engine, fuel system seals, and hose connections
• Plumbing fixtures, pumps, valves, and home appliance repairs
• General maintenance on tools, lanterns, toys, and RV/marine gear

How do I identify the right O‑ring size from the kit?

The organizer has individual compartments for each of the 32 included sizes labeled to match AS568 standards, making size checks straightforward. If you’re unsure, use a caliper to measure the inner diameter and cross-section; compare those figures to an AS568 size chart for a match.

• Refer to the printed compartment labels for quick reference
• Measure inner diameter and cross-section with a caliper for precision
• Use the included pick-and-hook tools to safely remove/install rings without damage

What precautions should I take when installing these O‑rings?

Proper handling and installation extend seal life and prevent leaks. Clean mating surfaces, lightly lubricate compatible surfaces with recommended grease or oil, and avoid stretching an O‑ring beyond its elastic limit. Use the supplied tools to position rings without nicking or tearing the rubber.

• Clean and dry the groove and mating surfaces before placing a ring
• Use compatible lubricants to ease installation and reduce abrasion
• Avoid sharp edges; use the pick-and-hook tools to position seals safely
• Replace any O‑ring that shows cracks, flat spots, or deformation

What does the kit include and how is it organized?

The set contains 1086 black Buna‑N O‑rings in 32 AS568 sizes and four metal pick-and-hook tools, all stored in a rigid clear plastic case. Each compartment holds multiple rings of the same size so you have spares for repeated maintenance jobs, and the case is compact enough to fit on a shelf or in a service bag.

• 1086 total O‑rings across 32 SAE/AS568 sizes for broad coverage
• Four durable pick-and-hook tools for safe installation and removal
• Clear plastic organizer with labeled compartments for quick selection

Who is this for? Technicians, mechanics, plumbers, RV and marine owners, and DIY homeowners who need a ready supply of standard O‑rings will find this kit practical. It’s also useful for workshops that handle routine maintenance where fast access to the correct SAE sizes reduces downtime. If your repairs involve very high temperatures, aggressive chemicals, or specialized elastomers (Viton, silicone), consider selecting a material better suited for those conditions.
