Compatible OmniFilter OB1 Series A Filter, Original O-Ring Black

As part of the OK-25 package, this item is only available in one size. It is important to note that if your original o-ring was blue, you should not purchase this particular product. For older OB1 models with the original blue o-ring, a smaller o-ring, which is part of the K-4 package, is required.

The original o-ring that came with your device was blue in color. If this is the case, you will need to acquire a smaller o-ring, which is included in the K-4 package, rather than the one size offered in the OK-25 package. Purchasing the OK-25 package item would not be the correct solution for your older OB1 model.

When it comes to maintaining and replacing o-rings, it is crucial to ensure that you select the appropriate size and type for your specific device. In this instance, the older OB1 model requires a smaller o-ring, which can be found in the K-4 package, not the single-size option provided in the OK-25 package.

It is essential to pay close attention to the original specifications of your device, including the color and size of the o-ring, to ensure that you obtain the correct replacement parts. Failure to do so may result in compatibility issues or improper functioning of your equipment.

Please note that the OK-25 package offers only one size of o-ring, and it is not suitable for older OB1 models with the original blue o-ring. Instead, you will need to source the smaller o-ring that is included in the K-4 package to properly maintain and repair your OB1 device.

In summary, if your original o-ring was blue, you should not purchase the item from the OK-25 package. For your older OB1 model, you will require the smaller o-ring that is part of the K-4 package. Ensuring the correct replacement parts is essential for the proper functioning and longevity of your equipment.
