Quick Verdict
If you need a working stock of rubber gaskets for pneumatic, hydraulic, or industrial automation jobs, the Parker Gaskets Qty. 95 Rubber Industrial Seals 4007SHD03750 gives you 95 gaskets in one purchase, with a 4 1/4-inch outer ring and 3 3/4-inch inner ring, listed at USD 57.78. The main catch is the condition: the package has been opened, though the gaskets are described as new with no visible wear. This suits people who go through seals in volume, not someone hunting for one retail-sealed gasket.
Who It Suits
This bulk lot is a practical fit for maintenance teams, equipment technicians, and hobbyists who regularly service pneumatic or hydraulic components and want a ready supply of seals on hand. It also works when your application already fits this part and you prefer to stock the same gasket across multiple jobs. If you only need a single seal or need a different ring size, a 95-piece lot is likely more than you require.
What Stands Out From the Listed Details
The biggest advantage is the count: 95 Parker gaskets identified by part number 4007SHD03750 in one purchase. The listing presents the condition as new other-original packaging opened, but the gaskets themselves in new shape and free of damage, wear, or use. That makes this less of a one-emergency-seal buy and more of a stock-the-shelf buy.
Meaningful Trade-Offs
The main trade-off is the open-box condition. Because the packaging has been opened, you are relying on the listing's description that the seals are unused rather than receiving an unopened retail package. The other trade-off is fit: the 4 1/4-inch outer and 3 3/4-inch inner ring dimensions are fixed, so you need to confirm your seal pocket or flange matches before committing to a 95-piece lot.

The primary reason to choose this lot is the combination of volume and a branded industrial seal: 95 Parker gaskets under part number 4007SHD03750. The limitation is the same thing that makes it appealing-it is a bulk buy, sold in opened packaging even though the gaskets are described as new. If you have recurring pneumatic or hydraulic jobs that use this seal, that is a reasonable trade-off; if you need one crisp retail pack, it is not.
Bottom Line
If your project calls for a large lot of Parker rubber gaskets for industrial pneumatic and hydraulic work, the 95-piece selection at USD 57.78 is a straightforward way to keep seals on hand. Confirm that the open-box packing is acceptable and that the ring size matches your equipment before ordering.
