Seals fail at the worst time. A blender starts leaking around the jar, or a plumbing fitting drips, and you need a replacement that actually fits. You can order a part made for that exact appliance, or you can keep a kit with enough seals to cover future repairs. In the seals, gaskets, and o-rings category, those two approaches come down to a head-to-head: a dedicated Hamilton Beach blender gasket against a broad o-ring assortment.
Quick Verdict
Choose the Hamilton Beach gasket if you have a Hamilton Beach blender with a leak between the jar and cutter. It is the precise part. Choose the o-ring assortment if you want a broad selection of nitrile o-rings for general repair work.
Comparison
| Product | Listed Price | Price Bar | Best For |

| O-Ring Assortment | USD 12.74 | General repair and future seal replacements |
Where Each Wins
Hamilton Beach gasket wins when you need to fix a specific blender. The gasket is shaped for the cutter-to-jar seal on Hamilton Beach domestic models and commercial units such as 908 and 909, so you don't have to sort through a bin of o-rings hoping one matches.
O-ring assortment wins when you need a working seal for multiple projects. It is ready for repair jobs and gives you flexibility, but only if the job calls for a round o-ring rather than a flat appliance gasket.
Product Notes
Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals

This gray replacement gasket is the direct fix for a Hamilton Beach blender that leaks around the cutter assembly. It measures 1.875 inches inside diameter and 2.68 inches outside diameter, and it is made to sit between the cutter and jar. It covers Hamilton Beach domestic models and commercial units such as 908 and 909, so if your machine matches that family, this part removes the guesswork of finding a ring that might not seal. The pack includes an extra gasket, so you have a spare ready for the next time the original wears out. The limitation is that it is a dedicated appliance part. It will not serve as a general-purpose o-ring for industrial fittings, so if your project is outside the blender, you need a different solution.
O-Ring Assortment Kit 400Pc Nitrile Rubber Metric Sizes Industrial Seals

This assortment is built for people who want an o-ring on hand before they need it. The nitrile rubber rings come in a labeled, resealable case with metric sizes from 4mm to 30mm and multiple thickness options, so you can grab the size that matches a plumbing joint or an automotive fitting. Nitrile is oil-resistant, heat-resistant, UV-resistant, and wear-resistant, which makes these rings a solid choice for repair projects. The kit gives you enough variety for many jobs. What it is not is a drop-in replacement for an appliance-specific gasket. The flat, thin washer shape that a Hamilton Beach blender needs is different from a round cross-section o-ring, so if you are fixing that blender, this kit is not the right part. Save it for general-purpose sealing.
Final Choice by Use Case
- For a Hamilton Beach blender in need of a new jar-to-cutter seal: choose the Hamilton Beach Blender Gasket at USD 6.99. The pack includes a spare, so you are covered for the next failure.
- For a general-purpose seal stash: choose the O-Ring Assortment at USD 12.74. The labeled, resealable case gives you options for future repair jobs.
