Quick Take
When you need replacement seals, gaskets, or O-rings, the challenge is not finding a rubber ring. It's matching the right part to the right job. A blender lid needs a flexible gasket that fits its blade assembly; a pressure cooker needs a heat-resistant ring; and a machine repair often calls for an O-ring that can handle oils and high temperatures. This guide compares four distinct options in the seals, gaskets, and O-rings space, with listed prices from $5.99 to $13.12. The $7.13 spread between the cheapest and most expensive set is real, but the more important difference is what each product is designed to seal.

Product Notes
AS568 010 Viton O-Ring
If your repair involves oils, fuels, or high temperatures, this Viton (FKM) O-ring is a solid starting point. The rings follow standard AS568 dimensions, and the 75 Shore A durometer gives a practical balance of flexibility and compression resistance. For a shop or hobbyist who needs one reliable size in bulk, this pack covers a lot of ground. The trade-off is that it's a specific dash size, so you need to know which groove you're filling. It also won't serve as a blender or pressure-cooker gasket.
AS568 012 Viton O-Ring
The next version in this line gives you the same Viton (FKM) material and 75 Shore A durometer, in a different standard dash size. If a machine or vehicle uses this particular O-ring size, this pack gives you a dedicated supply at the same listed price as the 125-pack. That price parity is worth noting: you get fewer rings, so this makes sense when the size is exactly what your equipment calls for. Like the other Viton option, this is aimed at O-ring grooves in machinery, not at kitchen appliance gaskets.
NutriBullet Blender Gasket Set
For a NutriBullet owner, these three gray gasket rings are the most direct fix for a leaking blender cup. The listing describes food-grade silicone rubber that is BPA-free and non-toxic, with an easy-clean design made for 600W and 900W blade assemblies. It's the only option here shaped as a blender gasket, so it fits that narrow job better than an O-ring or pressure cooker ring. The limitation is that it's a set for a particular class of NutriBullet and similar personal blenders, so compatibility depends on your cup's size and style. It won't seal a pressure cooker or replace a standard O-ring.
Pressure Cooker Sealing Ring Gasket
Pressure cookers need a seal that stays flexible in high heat, and this silicone gasket is built for that job. It's described as leakproof and is meant to keep the cooker airtight, so it's a practical replacement when the original lid ring wears out. The catch is that it's purpose-built for pressure cooker lids; it won't work as a blender cup gasket or an industrial O-ring, and you'll want to match it to your specific cooker's lid opening. If your pressure cooker lid has been leaking steam, this is the part to focus on.
Which Should You Choose?
If you're repairing a NutriBullet-style blender cup, go with the blender gasket set for NutriBullet. For a pressure cooker lid, the Pressure Cooker Sealing Ring Replacement Gasket is the pressure-cooker part to reach for. If you need industrial O-rings, choose between the two O-ring packs based on the dash number your equipment already uses. Match the dash number, and you'll have a reliable replacement.
