Quick Verdict
Two different repair jobs lead to this same shopping aisle: a blender that leaks, and a growing collection of o-rings that no longer fit anything. When you're comparing seals, gaskets, and o-rings, the first question is whether you need one exact replacement or a versatile selection.
If you are replacing a worn seal on a Hamilton Beach blender, the gasket set is the targeted fix. If you need a range of rings for faucets, car fittings, air lines, and gas fittings, the o-ring assortment gives you more flexibility for a $3.00 higher listed price.

Product Notes
Hamilton Beach 2-Pack Blender Replacement Rubber Plastic Gasket Ring Seals

The two-pack is the straightforward choice when the seal between the cutter and jar is the problem. These gaskets are designed for Hamilton Beach domestic blenders and commercial models such as the 908 and 909, and the 1.875-inch inner diameter by 2.68-inch outer diameter gives you a concrete size to match. Since the set includes two gaskets, you can replace the worn one and keep the second as a spare. The limitation is scope: this is a blender-specific part, not a general o-ring collection. If your repair list also includes faucets or car fittings, a separate o-ring assortment would be needed.
1050PCS O-Ring Assortment Kit | 21 Metric Sizes for Car Repair, Faucet, Air, Gas

This kit takes the opposite approach: instead of one dedicated part, it gives you 1,050 o-rings in 21 metric sizes, with inner diameters from 1mm to 25mm and thicknesses from 1mm to 4mm. The rings are made from commercial-grade nitrile rubber, so they are resistant to oil, water, heat, and abrasion, and the rated operating range of -40°F to 248°F makes them usable in many spots around the house or in a vehicle. They arrive in a compartment organizer with labeled sizes, which saves time when you need a specific ring. The trade-off is that you have to choose the right size yourself, and for a single known blender repair, a 1,050-piece assortment is more than you need.
Final Choice by Use Case
For a Hamilton Beach blender that is leaking around the jar base, the gasket set is the more direct match because it is sized specifically for the cutter-to-jar seal. For general maintenance, repairs on faucets, or any project where you need a variety of metric o-rings, the assortment is the better fit because its range and storage box give you ready options.
