How to Identify Fluid Ports and Connectors

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 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 illustration 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 March 20

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 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 March 20

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 March 20

How to Measure Sealing Surface Angles Female connections are usually measured by insert ing the gauge into the connection and placing it on the sealing surface. If the centerlines of the connection and gauge are paral lel, 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 March 20 7

American Connections NPTF (National Pipe Tapered Fuel) This connection is still widely used in fluid power systems, even though it is not recommended by the National Fluid Power Association (N.F.P.A.) for use in hydraulic applications. The thread is tapered and the seal takes place by deformation of the threads. Tapered Thread O.D. NPTF Threads Measure thread diameter and subtract 4-inch to find the nominal pipe size.

American Connections SAE J4 JIC/7 Hydraulic This connection is very common in fluid power systems. Both the male and female halves of the connections have 7 seats. The seal takes place by establishing a line of contact between the male flare and the female cone seat. The threads hold the connection mechanically. Caution: In the -02, -0, -04, -0, -08 and -0 sizes, the threads of the SAE 7 flare and SAE 4 flare are the same. However, the sealing surface angles are not the same.

American Connections SAE J8 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 J8, JIS B 86, ISO/DIS 662 and DIN 20066 are interchangeable, except for bolt sizes.

The design concept for both series is the same, but the bolt hole spacing and flanged head diameters are larger for the high pressure, PN 4 bar connection. Both metric and inches bolts are used. The port will have an M stamped on it if metric bolts are required. 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.

British Connections British Standard Pipe (BSP) The BSPT (tapered) connection is similar to the NPT, except that the thread pitches are different in most sizes, and the thread form and O.D. s are close but not the same. Sealing is accomplished by thread distortation. A thread sealant is recommended. The BSPP (parallel) male is similar to the NPSM male except the thread pitches are different in most sizes. The female swivel BSPP has a tapered nose/ Globeseal flareless swivel which seals on the cone seat of the male. 2 How to Identify Fluid Ports and Connectors E-SROV-TS009-E March 20

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 20066 and SAE J8 are interchangeable, except for bolt sizes. 8 How to Identify Fluid Ports and Connectors E-SROV-TS009-E March 20

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 in-plant 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 Tapered Straight Thread Thread O.D. Thread O.D.
