3 Welcome to the Eaton Weatherhead series of Hydraulic Product Training focusing on key topics to assist you in servicing your hydraulics customer base.Eaton’s Hydraulic Group is a worldwide leader in the design, manufacture and marketing of a comprehensive line of reliable, high-efficiency, hydraulic systems and components.Weatherhead has one of the industry’s broadest offerings of hose and fittings that are widely used through out multiple market applications.Click Next >> to continue.
4 Hydraulic hose assemblies come in a wide variety of lengths, sizes, and end fitting configurations. In this module, you will learn why hose and fitting identification is so important when building hydraulic hose assemblies. These assemblies often have high pressure, high temperature fluids flowing through them. Attention to product specifications is critical to everyone’s safety.Accurate identification of ports and connectors in fluid systems is necessary before the correct hose assembly can be selected. Be confident that the replacement provided to your customer is the right one, the first time.Click Next >> to continue.
5 These training topics are designed to provide a meaningful understanding of hose and fitting identification with a focus on the most frequently seen assemblies in the marketplace.Port and connector basicsDimensions cross reference reviewCommon measurement toolsHydraulic hose typesCommon connector stylesMeasuring threads for various connector stylesUsing thread identification charts to lookup connector types
6 The purpose of a hydraulic system is to transfer hydraulic pressure in order to perform a mechanical operation like extending a cylinder. This training will focus on the hose assembly. Typically the hose assembly is the most commonly replaced item in the hydraulic system because of its constant flexing and exposure to harsh environments. PUMPPORTHOSEASSEMBLYADAPTERCOMPONENTHOSE END

Having the proper tools on hand, is a key contributor to successful thread identification.The FT1341 is a thread measuring tool kit, which also includes a booklet of charts and information about numerous types of connections.There are three measuring tools recommended to quickly measure a connector in hand:A thread pitch gaugeA seat angle gaugeAn I.D/O.D caliperThread pitch gaugeReferenceGuide2 in 1 seat angle/caliper toolUse the reference guide to quickly convert your measurements into a part numberClick Next >> to continue.

A thread pitch gauge is used to measure two types of threads:Non metric: Number of threads per inch for non-metric connectorsMetric: Distance between threads for metric connectorsThread pitch gaugeA seat angle gauge is used to measure the sealing surface of both male and female connectors.The caliper is used to measure the thread diameterRollover on text.

These charts will be reviewed in more detail later in the course.Reference charts used for connector selection focus on the following characteristics:Thread diameterThread pitchSeating angleClick Next >> to continue.

12 Click Next >> to continue. Hose failures are often due to age, improper use, poor assembly, or poor installation. Proper hose identification is the first step in the replacement process.Start by inspecting the hose for a layline. A layline may contain the following information:ManufacturerHose namePart numberHose pressure ratingHose I.D. (inner diameter)Industry standard numberManufacturer/BrandHose NameIndustryStandardNumberPartNumberHoseI.DAnother key piece of information is the application, be sure to ask how or where the hose assembly was used, and on what type of equipment it was used on.Click Next >> to continue.
13 If a layline isn’t visible, an inspection of the hose construction may offer some clues. Hoses may have a braided, or spiral construction with different exterior cover styles depending on the application.Braided hose can have 1 or 2 layers- Braids can be fiber, steel or combination of bothSpiral hose can have 4 or 6 layers- Spiral plies are usually steelRubber hose is typically a single fiber braidClick Next >> to continue.

15 Question 3A customer brings in a broken hose assembly. What steps should you take to identify the hose type?Select the best answer, then click Submit.A. Inspect the hose for a layline identifier such as manufacturer, or hose specificationsB. Ask the customer what application the hose assembly was used onC. Inspect a cross section of the hose for a spiral or braided patternD. All of the aboveMultiple Choice, two attempts, fixed option sequence, do not score responseCorrect Answer: ACorrect Feedback: That is correct.

16 Now that you’ve reviewed hose identification, let’s now learn how to determine what connection to use on each end of the replacement assembly.Selecting the right connector starts by knowing what types of connectors to look for.Here is a list of popular connector types: (click on each for more detail)NPTF: National Pipe Tapered Fuel (LINK TO SLIDE 23)JIC: SAE J Deg Flare (LINK TO SLIDE 20)ORFS: O Ring Face Seal SAE J1453 (LINK TO SLIDE 21)Flange:BSP: British Standard Pipe (BSPP Parallel & BSPT Taper) (LINK TO SLIDE 19)JIS:Metric/Komatsu: DIN 3902 & Komatsu (LINK TO SLIDE 22)
17 British Standard Pipe Parallel British Standard Pipe Tapered Parallel (straight) thread with a constant diameter - The BSPP thread is parallel and the male has a 30° flare seat which seals with a BSPP female on its 30° cone seat. The threads hold the connection mechanicallyThe BSPP is similar to NPSM connections with exception of the thread pitch, which that is different in most sizes.• The BSPT male thread has tapered threads and a 30° inverted seat. The seal takes place by thread distortion.• The BSPT male mates with a BSPT Female usually found as a port connection.• The BSPT is similar to but not interchangeable with NPTF. The thread pitch is different in most sizes and the thread angle is 55° degrees.
18 JIC: SAE J Deg FlareThis connection is very common in fluid power systems. Both the male and female connections have 37 degree 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.(Insert Image)
19 ORFS: O Ring Face Seal SAE J1453 This connection offers the very best leakage control available today. The seal takes place by compressing the O-Ring onto the flat face of the female. The threads hold the connection mechanically.(Insert Image)
20 Metric: DIN 3902 SeriesThis connection style consists of a common male and three different female halves.The male has several features:a straight metric threada 24 degree included anglea recessed counterbore that matches the tube O.D.The female has several configurations:a tube, nut and ferrulea tapered nose/globeseala tapered nose/globeseal with an o-ring
21 NPTF: National Pipe Tapered Fuel This connection is a tapered thread connector. The seal takes place by deformation of the threads. Thread crests are crushed into mating thread root causing a full metal to metal contact.While it is still used in fluid power, its not recommended as the best option.
22 -06 JIC should be the 37 degree angle A recommended part to use for this section to use as an example would be a straight adapter -06 Male Pipe x -06 Male JIC.-06 JIC-06 Male PipeStep 1 Measure the thread pitchHolding the fitting straight, place the thread pitch gauge on the threads until the fit is snug.Determine the number of threads per inch or the distance between threads in metric connections.Step 2 Measure the thread I.D or O.DUsing the caliper, measure the O.D. of the male thread or the I.D. of the female thread.Step 3 Measure the angle of sealUsing the tip of the caliper, or a seat angle, measure the angle of the sealing surface (37° & 45° are most popular)If angle is a 12 or 24 degree sealing surface, an additional measurement called the ‘r’ dimension is required *Step 4Refer to the proper reference chart found in your Eaton Weatherhead Master Catalog to look up the numbers measured using steps 1 -3-06 JIC should read 18 threads per inch-06 JIC should read 9/16” ODRollover on text.
