Last updated Aug 17, 2026

Quick Take

The four listings here cover three distinct sealing jobs plus one catch-all assortment. There is an o-ring set for a specific standard size, an o-ring assortment with many sizes, an industrial oil seal pair with fixed dimensions, and a blender jar gasket replacement. The decision starts with the application: exact replacement part or a selection of sizes for general repair. The table below shows the listed price and the quantity in each package.

Product Notes

AS568-235 Buna 70 Duro O-Ring Set Qty 25

AS568-235 Buna 70 Duro O-Ring Set Qty 25 Hydraulic Industrial Seals NOS

This is a package of 25 o-rings, all listed as AS568-235 size in Buna (nitrile) with a 70 durometer hardness. That combination is a common choice for hydraulic, pneumatic, industrial, automotive, fuel, and oil sealing applications. It is a good fit if your equipment specifies AS568-235 and you prefer having multiple spares for one repair. The limitation is that you get only that one size; there is no variety across other dash numbers, so it will not help if your other components use different AS568 sizes.

O-Ring Assortment Kit 400Pc Nitrile Rubber Metric Sizes

O-Ring Assortment Kit 400Pc Nitrile Rubber Metric Sizes Industrial Seals

When you need coverage across many metric O-ring sizes, this 400-piece kit is the broadest option in the lineup. The rings are nitrile rubber with metric outer diameters from 4mm to 30mm and thicknesses of 1mm, 1.5mm, 1.9mm, 2.4mm, and 3.1mm. Each ring sits in a labeled, resealable container, which helps when sorting for a repair. The trade-off is that no single size gets you a large quantity; you are buying the assortment as a set. If you already know a particular metric size, a dedicated pack of that one size would give you more of what you need. The kit is a useful starting point for plumbing and automotive repairs where the exact ring size is not yet known.

NEW IN BOX LOT OF 2 SKF 1.375" x 2.125" x .313" Industrial Oil Seals 13649

NEW IN BOX LOT OF 2 SKF 1.375" x 2.125" x .313" Industrial Oil Seals 13649

This lot gives you two SKF oil seals with the same fixed dimensions: 1.375" inside, 2.125" outside, and .313" thick. The MPN 13649 and brand SKF are printed on the box, so you can match the part number to your equipment. Having two seals in one box is convenient when you need a spare for the same application. The part is listed as new in box, so the package is ready to open for the repair. The obvious limitation is that this is a fixed-size part; it will not work for any other shaft or bore combination, and the count is exactly two, not more.

Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals

Hamilton Beach 2 Pack Blender Replacement Rubber Plastic Gasket Ring Seals

These are two gray gaskets built as a replacement for Hamilton Beach blenders. The flat o-ring washer sits between the cutter and the jar, and fits Hamilton Beach domestic models as well as commercial models 908 and 909. The measurements are 1.875" inside diameter and 2.68" outside diameter, so you can compare against the part you remove. The brand shown is Felji and the listing type is a replacement blender part. If you have a leaking Hamilton Beach blender jar, this two-pack gives you a dedicated replacement; it is not intended for general plumbing or industrial sealing. The gray color makes the gaskets easy to spot when the blender is disassembled.
