Some sealing jobs call for a precise fit; others call for a convenient general-purpose supply. Before you choose between a dedicated backhoe dipper cylinder seal kit and a bulk pack of AS568-010 Viton O-rings, the real question is whether you're rebuilding one known cylinder or restocking a drawer for many repairs. In the seals gaskets o rings aisle, $9.99 buys a lot of versatility, while $35 buys a targeted solution. Your choice comes down to how specific the job is.
Quick verdict
If your project is resealing the dipper cylinder on a Case 580K / 580SK / 580SL-family machine, the Backhoe Dipper Hydraulic Cylinder Seal Kit at $35 is the focused option. If you need a versatile supply of AS568-010 Viton O-rings, the Macho O-Ring pack at $9.99 is the practical one. Let the job, not the price, make the call.

Where each product wins
The seal kit wins when you're working on a specific Case dipper cylinder. It's not a random assortment; it's a targeted kit for that hydraulics application. The rod and bore specs are matched to the intended cylinder, so the order is far more specific than a random O-ring lot.
The O-ring pack wins when you need standard seals for a range of equipment and everyday repairs. The AS568-010 profile is a common size, and the compound is suited to demanding environments. If you'd rather have spare O-rings on the shelf than a single cylinder-specific kit, this is the direction to go.
Backhoe Dipper Hydraulic Cylinder Seal Kit for CASE Industrial 580K 580SK 580SL
This kit is for a particular job: the backhoe dipper cylinder on Case machines in the 580K / 580SK / 580SL family. It's specified for a 2.50-inch rod and 5.00-inch bore, and the OEM cylinder numbers include 126151A1, 183795A1, and G110694. That makes it a much more targeted order than picking a generic O-ring lot.
The trade-off is the same focus that makes it useful. It isn't a general assortment, and it's meant for the listed Case loader/backhoe and crawler tractor-loader applications rather than a universal seal drawer. If the cylinder you're repairing matches those specs, this is the straightforward option.
AS568 010 Black Viton O Rings 75 Durometer FKM Seal 125 Pack Macho O-Ring
The strength of this pack is in its utility. Each ring is made to the AS568-010 standard size, and the 75 Shore A durometer FKM compound is suited to jobs where chemicals, oils, or high temperatures are part of the environment. With 125 pieces in one box, you can keep a working supply at the shop instead of ordering single replacements.
The limitation is that this is one AS568 size-the 010-rather than a range of O-ring sizes. It also isn't a cylinder-specific seal kit, so a hydraulic rebuild may need additional seals beyond what an O-ring pack provides. For matching AS568-010 replacements, this is the easy maintenance stocker.
Final choice by use case
Pick the Backhoe Dipper Hydraulic Cylinder Seal Kit when you have a compatible Case dipper cylinder to rebuild and want the seal set sized for that cylinder. Pick the AS568 010 Black Viton O Rings 125 Pack when you want a durable O-ring supply for repeated, general-purpose sealing jobs. Each one makes sense for a different workshop.
