Seals, gaskets, and O-rings fail when you least expect them, and a single missing size can stop a repair. These four O-ring assortment kits tackle that problem with 1,050 or 1,540 pieces, priced from $8.86 to $35.99. The decision comes down to how many metric sizes you need, whether you want a pick set, and how much you want to spend.
Quick take
If you just need a low-cost metric assortment, the O Ring Kit 1050 PCS at $8.86 gives you 1,050 nitrile rings in 21 sizes. If you want the largest selection and a tool set, the ZDBB 1540pc Metric O Ring Kit at $35.99 includes 32 sizes, 1,540 rings, and four picks. The 1050Pcs O Ring Kit at $11.99 and the 1050PCS O-Ring Assortment Kit at $9.99 sit in between, both with 1,050 pieces and metric coverage.

Product notes
1050Pcs O Ring Kit
This $11.99 kit holds 1,050 O-rings and is described as compatible with universal vehicles and auto repairs. The plastic organizer case has labeled compartments, and the rings cover inner diameters from 1mm to 25mm, making it a flexible addition to a car or workshop. The nitrile rubber material resists high and low temperatures, per the product description. If you want a compact, labeled set with 1,050 pieces, this kit is a reasonable pick. The limitation is that it's the priciest of the three 1,050-piece kits here, and the 1,050-piece count means fewer spares than the ZDBB's 1,540.
ZDBB 1540pc Metric O Ring Kit
At $35.99, this is the priciest of the four kits. It comes with 1,540 nitrile O-rings in 32 metric sizes, plus four picks and hooks for removing and installing seals. The description highlights resistance to oil, fuel, water, and wear, which suits automotive, plumbing, air, gas, and hydraulic work. For anyone who regularly repairs multiple machines, the 32-size spread and included tools make the higher price easier to justify. The trade-off is that it costs $27.13 more than the $8.86 kit, so it makes sense only if you need that extra coverage and the pick set.
O Ring Kit 1050 PCS
The $8.86 price makes this the least expensive way to get 1,050 nitrile O-rings in 21 sizes. The description lists inner diameters from 1mm to 25mm and thicknesses from 1mm to 3mm, and the case uses labeled compartments for storage. This is the kit to grab when you want a broad metric assortment without spending much. The color is black, and the material is nitrile rubber, a common choice for general sealing. Since the price is so low, you can add a separate pick set later if you need one. Just keep in mind that 1,050 pieces is fewer than the 1,540-ring ZDBB kit.
1050PCS O-Ring Assortment Kit
Priced at $9.99, this kit costs slightly more than the $8.86 option but adds a few specifics. It's described for universal utility vehicles and seals, the country of origin is the United States, and the features call out wear resistance. The 1,050 O-rings come in 21 metric sizes with inner diameters from 1mm to 25mm, and the organizer keeps each size labeled. If you prefer US origin and wear-resistant material for a modest price bump, this is a solid middle choice. The limitation is that you get the same 1,050-piece count and 21-size range as the cheaper kit, so the extra dollar goes to those secondary attributes.
Final recommendation
For a cheap starter kit, the O Ring Kit 1050 PCS at $8.86 is the practical pick. For large-scale metric coverage with tools, the ZDBB 1540pc Metric O Ring Kit at $35.99 is the one to buy. If you want a wear-resistant US-made set, the 1050PCS O-Ring Assortment Kit at $9.99 is the best fit. The 1050Pcs O Ring Kit works as a universal spare set, but at $11.99 it's the most expensive way to get 1,050 pieces.
