NBRINGO O-Ring Kit 826-Piece SAE & Metric Assortment — 70A Nitrile, Case + 4 Picks

NBRINGO 826-piece O-ring kit is a comprehensive Nitrile (Buna‑N 70A) assortment of SAE and Metric seals organized in a durable compartment case with four pick tools for quick repairs.

This kit gathers the most commonly used O-ring sizes for automotive, plumbing, hydraulic and general mechanical repairs into one portable set. The rings are made from 70A durometer Nitrile (Buna‑N), chosen for oil and fuel resistance and reliable compression in standard temperature conditions. Everything is sorted by size for fast selection, and the included pick and hook tools help extract old seals from tight grooves.

What sizes are included and how is the assortment organized?

The set contains 826 pieces spanning both SAE and Metric ranges, arranged across labeled compartments so you can identify sizes at a glance. It provides two full standard sets of 32 SAE sizes and 32 Metric sizes with multiple counts of each diameter, suitable for common service tasks.

• Labeled compartments for each size enable quick part selection.
• Multiple rings per size reduce repeat ordering during maintenance.
• Includes both inch (SAE) and millimeter (Metric) standards for cross‑compatibility.

What material are the O‑rings and where are they best used?

The seals are molded from commercial‑grade Nitrile (Buna‑N) at approximately 70A durometer, balancing flexibility with resistance to oils, fuels and hydraulic fluids. That makes the kit well suited to engine components, fuel systems, hydraulic fittings and many household plumbing connections under typical operating temperatures.

• 70A durometer for durable compression set resistance in general service.
• Good compatibility with petroleum‑based fluids and greases.
• Suitable for automotive, pneumatic, hydraulic and faucet applications.

How do the included tools and case improve repairs?

The kit ships with four pick and hook tools that make removing old O‑rings and seating new ones faster and cleaner. A clear, compartmentalized case keeps every size visible and protected, reducing the chance of losing small seals while you work.

• Four assorted pick hooks for extraction and installation in tight spaces.
• Transparent case for instant size recognition and inventory checks.
• Burr‑free rings for smoother installation and extended service life.

Who is this for: The NBRINGO 826-piece O‑ring assortment is aimed at mechanics, plumbers, maintenance technicians and DIYers who need a broad range of reliable seals on hand. It is practical for shop benches, service vans and home repair toolboxes when you want immediate access to multiple SAE and Metric sizes without multiple small orders. Confirm the specific O‑ring diameter and cross‑section required for your application before installation to ensure proper sealing performance.
