Identify the correct size
This oil level sight gauge corresponds to Figure 530, size 0. The source's size table covers several configurations, but this page is linked to OG5300 only. The size number matters because the shank thread, height and glass dimensions change within the family.
Start with the exact equipment part reference and the gauge's installation drawing. A general description such as a small shielded gauge is not enough to identify the correct size. This request does not include the other Figure 530 sizes or a custom combination of their dimensions.
Shank and centerline measurements
For size 0, the listed pipe thread on the shank is 1/8 inch. The length from the glass centerline to the end of the shank is 1 3/4 inches. The height from the shank centerline to the top of the gauge is 2 9/16 inches. Both lengths have defined starting points; they are not interchangeable with the overall bounding-box dimensions of the part.
Check those reference points against the space around the equipment connection. When measuring an existing installation, record which centerline each measurement starts from. This helps distinguish a genuinely different gauge from one that has simply been measured from a different edge.
Glass dimensions and what remains to confirm
The size-0 row specifies a glass length of 1 7/8 inches, and the table states a glass diameter of 5/8 inch. The glass length differs from the centerline-to-top height. Keep these separate when comparing a replacement gauge or a parts drawing.
This page does not establish a pressure or temperature rating for your installation. The shielded description also does not establish compatibility with a particular oil or a specific machine. Those application details need to be confirmed from the appropriate equipment and component documentation before purchase.
Comparing an oil level sight gauge
Make the initial comparison in three steps: identify the exact gauge reference, check the connection specification, then check the dimensions from the specified centerlines. Finally, compare the glass dimensions. Do not infer a thread standard or use a nominal pipe-thread size as a measurement of the outside of the shank.
The illustration helps identify the general shielded form. It is not a substitute for a dimensional drawing or an inspection of the connection. No replacement glass, fittings or installation hardware are represented as included in this request. If you need those separately, their exact references must be confirmed rather than assumed from the picture.
Request one gauge or several
One proposed request unit represents one OG5300 gauge in the size-0 configuration. Enter the number required and review the exact SKU alongside your name and email. Selecting a quantity does not reserve inventory or establish a final unit price.
The final confirmation is an expression of interest only. We will confirm availability, final price and delivery timing before any purchase. The request form does not collect payment information, create an order or authorize fulfillment. Keep your original machine reference available for any later clarification of the gauge specification.
Questions about OG5300
- Which oil level sight gauge size is this?
- It is Figure 530 size 0, linked to OG5300. Other sizes in the source table are separate configurations.
- Is the listed height the glass length?
- No. The 2 9/16-inch height starts at the shank centerline. Glass length is listed separately as 1 7/8 inches.
- Does ⅛ inch describe the glass diameter?
- No. It describes the pipe thread on the shank. The listed glass diameter is 5/8 inch.
- Can I select another size in this request?
- This page records interest in OG5300 size 0 only. Another size needs a separate verified product match and supply confirmation.
