Before you pick any replacement seal, the real question is what you are trying to repair. A general-purpose O-ring assortment can restock your toolbox with standard-size seals, while a dedicated blender gasket set is a much narrower fix for one kind of leaking cup. One is a bulk pack for standard O-ring sizes; the other is a small appliance-specific kit. These two products sit on opposite sides of the seals, gaskets, and O-rings aisle, and each one is the better choice for a different job.
Quick verdict
If you maintain tools, automotive parts, or industrial equipment and want a broad stock of standard O-rings, the AS568 010 Viton O-Ring pack is the stronger buy at $9.99. If you have a NutriBullet 600W or 900W blender with a worn-out seal at the blade base, the NutriBullet gasket set costs $5.99 and makes that repair much more direct. Match the product to the repair you actually have, and the decision narrows quickly.
Comparison
| Product | Listed Price | Quantity | Best For |
| AS568 010 Viton O-Ring 125-Pack | $9.99 | 125 O-rings | General equipment sealing jobs |
| NutriBullet Gasket Set 3-Pack | $5.99 | 3 gasket rings | NutriBullet 600W/900W blender repair |
Where each product wins
The AS568 010 Viton O-ring pack wins when you need an assortment of AS568-size O-rings. The Viton/FKM material and 75 Shore A durometer suit chemical, oil, and high-temperature sealing work, which gives one box a lot of reach across different repairs.
The NutriBullet gasket set wins when the repair is already identified: a leaking 600W or 900W NutriBullet blade assembly. The food-grade silicone rubber is built for blender duty and easy to clean, which matters for something that touches food. It is not a replacement for a full O-ring assortment, but it is a much more targeted purchase for this appliance.
Product notes
AS568 010 Black Viton O Rings 75 Durometer | FKM Seal | 125 Pack | Macho O-Ring
This is a bulk spare-parts answer. You get 125 AS568-010 O-rings made from Viton/FKM at a 75 Shore A durometer, and that material points toward automotive, industrial, and other demanding sealing jobs. The pack works best when you want one box of standard-size O-rings for a toolbox rather than a single appliance fix. It gives you enough spares to handle recurring seal replacements or multiple pieces of equipment. The trade-off is quantity: 125 rings is more than you need if a small repair calls for one seal. Keep this as the general-purpose option and reach for a shaped blender gasket when the job is specifically a NutriBullet blade assembly.
3PCS Gasket Seal Rings for NutriBullet 600W 900W Blender Replacement Parts
If your blender cup has started leaking at the blade base, this three-piece set is the direct route back to working. It is sold for NutriBullet 600W and 900W blade assemblies, uses food-grade silicone rubber, and the easy-clean material suits something that touches food. Because the set comes with three gasket rings, you can replace the worn seal and still have a spare or two when the next one wears out. The catch is the same specificity that makes it convenient: it is a three-ring kitchen repair kit, not a general-purpose O-ring assortment. You will not be restocking a full seal drawer with this, but you will have the right replacement part for a common blender failure. Choose it when the leaking blender is the project and you want a replacement part made for that repair.
Final choice by use case
For general equipment, automotive, or industrial sealing projects, choose the AS568 010 Viton O-Ring pack. For a NutriBullet 600W or 900W blender seal replacement, choose the 3PCS Gasket Seal Rings. Match the seal to the job, and the right purchase is clear.
