Thread Identification Kit
There are many types of North American threads, as well as
British, German, French and Japanese threads. With all the
thread types and styles available, it is important to properly
identify a fitting so that an assembly can be connected
correctly within the hydraulic system. This kit and the tools
inside will help you identify a broad selection of different
thread types.
The Thread Identification Kit includes:
Fitting Identification Manual
North American (NA) Thread Pitch Gauge
International (INT) Thread Pitch Gauge
Seat Angle Gauges 12°, 30°, 37°, 45°
ID/OD 3.5” Calipers
Part Number: Fitting IID Pocket Guide
Dimensions: 4

Steps to Identify a Fitting
1.
Select country of origin for the fitting. Use part
number if available to determine thread type.
2.
Identify the fitting visually using the illustrations
in the proper section of the Continental
ContiTech Hydraulic Hose and Fittings Catalog
or the Hydraulic Fitting Identification Manual
included with the identification kit.
3.
Measure the inside diameter or the outside
diameter of the fitting threads using the ID/OD
Calipers.
4.
Measure thread pitch using the North American or
International Thread Pitch Gauge. The gauge will determine
number of threads per inch or the distance between
threads of a metric connection.
6.
Compare measurements above to the tables in the
fitting catalog or identification manual to complete the
identification of the fitting.
5.
Measure the angle of the fittings sealing surface using the
Seat Angle Gauge.
