1 How to Identify Fluid Ports and Connectors

2 Foreword Accurate identification of ports and connectors in fluid piping systems is necessary before the correct hose or tube assembly can be selected and installed. With the aid of this booklet and a few simple tools, measurement and identification is easy. Most connectors commonly used in fluid piping systems are included in this booklet. The connections are listed under headings divided by the country of origin to provide further assistance in identification. Please consult your Eaton representative for assistance in identifying connectors not found in this booklet. How to Use This Booklet Visually identify the part by comparing it with the artwork shown for each type of connection. Take measurements of the I.D., O.D., threads and angles as appropriate. Compare the measurements to the charts to convert to the correct dash and/or thread size and the parts series. 2 How to Identify Fluid Ports and Connectors E-SROV-TS009-E November 200

5 Tools Measuring Tools A seat angle gauge, thread pitch gauge and an I.D./O.D. caliper are necessary to make accurate measurements of commonly used connectors. Eaton offers a unique new caliper that offers the capabilities of both a caliper and a seat angle gauge in one unit. I.D./O.D. Angle Gauge Caliper Thread Pitch Gauge How to Identify Fluid Ports and Connectors E-SROV-TS009-E November 200 5

6 Threads How to Measure Threads Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug. Match the measurement to the charts. Measure the thread diameter with an I.D./O.D. caliper as shown. Match the measurements to the charts. I.D. O.D. 6 How to Identify Fluid Ports and Connectors E-SROV-TS009-E November 200

7 Seat Angles How to Measure Sealing Surface Angles Female connections are usually measured by inserting the gauge into the connection and placing it on the sealing surface. If the centerlines of the connection and gauge are parallel, the correct angle has been determined. Male flare type connectors are usually measured by placing the gauge on the sealing surface. If the centerlines of the connection and gauge are parallel, the correct angle has been determined. How to Identify Fluid Ports and Connectors E-SROV-TS009-E November 200 7

17 American Connections SAE J58 4-Bolt Flange* This connection is commonly used in fluid power systems. There are two pressure ratings. Code 6 is referred to as the standard series and Code 62 is the 6000 psi series. The design concept for both series is the same, but the bolt hole spacing and flanged head diameters are larger for the higher pressure, Code 62 connection. The female (port) is an unthreaded hole with four bolt holes in a rectangular pattern around the port. The male consists of a flanged head, grooved for an O-Ring, and either a captive flange or split flange halves with bolt holes to match the port. The seal takes place on the O-Ring, which is compressed between the flanged head and the flat surface surrounding the port. The threaded bolts hold the connection together. *SAE J58, JIS B 86, ISO/DIS 662 and DIN are interchangeable, except for bolt sizes.

38 Japanese Connections JIS B 86 4-Bolt Flange* This connection is commonly used in fluid power systems. There are two pressure ratings. Type I (Code 6) is referred to as the standard series, and Type II (Code 62) is the 6000 psi series. The design concept for both series is the same, but the bolt hole spacing and flanged head diameters are larger for the higher pressure, Type II connection. Both metric and inch bolts are used. The female (port) is an unthreaded hole with four bolt holes in a rectangular pattern around the port. The male consists of a flanged head, grooved for an O- Ring, and either a captive flange or split flange halves with bolt holes to match the port. The seal takes place on the O-Ring, which is compressed between the flanged head and the flat surface surrounding the port. The threaded bolts hold the connection together. *JIS B 86, ISO/DIS 662, DIN and SAE J58 are interchangeable, except for bolt sizes. 8 How to Identify Fluid Ports and Connectors E-SROV-TS009-E November 200

42 Oil Pan-Plug Threads How to Identify Oil Pan-Plug Thread Sizes These connections are found on engine oil pans of all types ranging from on and off road vehicles, marine vessels, and construction equipment, to inplant equipment fluid reservoirs. The thread styles range from straight threads with no chamfers to NPTF threads. Eaton has selected a single jacketed copper crush gasket to use on all FLOCS coupling and adapter straight threads where sealing is against the pan itself. In these applications there will be plugs on the equipment to measure, so the male thread dimension is given in this chart. NPTF Thread Straight Thread Tapered Thread O.D. Thread O.D.
