Pin Seal Diameter Gages
Pin Seal Diameter
The Pin Seal Diameter Series of gages inspect critical pin seal diameters and seal tapers on premium connections. With the addition of stand-off plates, the gages also inspect seal tapers. Each model covers a specific range of connection sizes, making the PN series (PN, PNI, PNA, PN-30) of gages extremely versatile and economical.
The PN gages use precision interchangeable contact points that position on the seal at a fixed distance from the connection face during inspection.
Before inspecting parts, these gages must be preset to a nominal predetermined dimension using gage blocks, Gagemaker’s Pin Seal Diameter Gage Setting Master, a MIC TRAC Gage Setting System, or frame standards. All setting equipment sold separately.
For replacement parts or customer specific versions of our pin nose gages, please contact customer service.
Features
- Provides accurate measurements on the gage’s indicator at the critical sealing point of the pin.
- Uses interchangeable contact points.
- Available with a .0005″, .0001″, or metric resolution indicator.
- Requires presetting using gage blocks, Gagemaker’s Pin Seal Diameter Gage Setting Master, Frame Standards, or a MIC TRAC system.
- Allows use in manufacturing or field environment due to durable construction.
The PN series measure pin nose diameter using contact points. Specify the distance from the face of the connection to the measuring plane and desired contact point diameter when ordering. Gages for larger ranges may be available as a custom order.

There is a separate cost to reposition the point standoff of PN-3000 Gages. Quotation available upon request.
The PNI series use ball contacts to measure the internal seal diameters of pins. When ordering, specify the desired contact point diameter and the distance from the connection’s face to the measuring plane (standoff). Gages with additional or more specific options may be available as a custom order.
