Seals, gaskets, and O-rings are small, but when one fails, the repair can hinge on getting the right part. You can buy the exact seal for one appliance or invest in a box that covers many possible jobs. Here, the decision is between a replacement gasket set for Hamilton Beach blenders and a metric O-ring assortment with pick tools. The better choice depends on whether your repair is already identified or still unknown.
Quick verdict
For a known Hamilton Beach blender leak, the gasket set is the more direct path: it's a low-priced replacement that targets the blender seal. If you would rather keep a range of metric seals at hand for automotive, plumbing, pressure washer, air, gas, or hydraulic repairs, the ZDBB assortment is the broader tool. Use the Hamilton Beach set to fix one blender, the ZDBB kit to be ready for many.

Where each product wins
Where the Hamilton Beach set wins: it is a direct replacement part for recognized Hamilton Beach domestic and commercial blenders, and the seal shape is specific to the seal location for this blender family. Where the ZDBB kit wins: it gives you a wide supply of O-rings in popular metric sizes, a set of picks to remove and install them, and a storage case to keep everything organized. That's useful when you don't know which size you'll need next.
Product notes
Hamilton Beach Blender Replacement Gasket

The first path is a focused one. This set includes two gray gaskets that serve as flat O-ring washers between the blender cutter and jar. It is intended for Hamilton Beach domestic blenders and commercial models such as 908 and 909, so the fit is aimed at a particular family of machines rather than a universal seal. The gaskets measure roughly 1.875 inches inside diameter and 2.68 inches outside diameter, which tells you the repair is for a specific size. The strongest reason to choose it is that you get a matched replacement part and a spare in one small purchase. The limitation is just as clear: because both gaskets are the same size, the set won't help with different diameters or with non-blender equipment. It solves a single known problem, not a workshop full of seal jobs.
ZDBB Metric O-Ring Kit

The second path is the opposite. This kit supplies a large assortment of nitrile rubber O-rings organized in a storage case, along with a four-piece pick and hook set. Nitrile rubber is chosen for its resistance to oil, fuel, water, and wear, which makes the kit relevant to automotive, plumbing, pressure washer, air, gas, and hydraulic repairs. The practical strength of the assortment is versatility: you can reach for it when a metric-fitting leak appears and simply find the size you need. The clear limitation is that it is metric-only and O-ring based, so it does not include the flat washer-style gasket the Hamilton Beach set is made for. If your job calls for an inch-based seal or a blender-specific component, this box will not be the final answer.
Final choice by use case
If you already know the fault is in the seal on a Hamilton Beach blender, choose the Hamilton Beach gasket set. If you maintain equipment with metric O-ring fittings and want a single box to draw from for multiple repairs, choose the ZDBB metric O-ring kit.
