Eaton Weatherhead Training Series Hose & Thread Identification 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.

Eaton Weatherhead Training Series Hose & Thread Identification 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 basics • Dimensions cross reference review • Common measurement tools • Hydraulic hose types • Common connector styles • Measuring threads for various connector styles • Using thread identification charts to lookup connector types

Eaton Weatherhead Training Series Hose & Thread Identification 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.

Eaton Weatherhead Training Series Hose & Thread Identification 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: 1. A thread pitch gauge 2. A seat angle gauge 3. An I.D/O.D caliper Reference Guide Thread pitch gauge Use the reference guide to quickly convert your measurements into a part number 2 in 1 seat angle/caliper tool

Eaton Weatherhead Training Series Hose & Thread Identification You will also use a series of reference charts to determine which connectors to consider. These charts will be reviewed in more detail later in the course. Reference charts used for connector selection focus on the following characteristics: • Thread diameter • Thread pitch • Seating angle

Eaton Weatherhead Training Series Hose & Thread Identification 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: Manufacturer Hose name Part number Hose pressure rating Hose I.D. (inner diameter) Manufacturer/ Brand Hose Name Industry standard number Part Number Hose I.D

Industry Standard Number Another 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.

Eaton Weatherhead Training Series Hose & Thread Identification 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 both Spiral hose can have 4 or 6 layers - Spiral plies are usually steel Rubber hose is typically a single fiber braid

Eaton Weatherhead Training Series Hose & Thread Identification 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 J514 37 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)

Eaton Weatherhead Training Series Hose & Thread Identification •

British Standard Pipe Parallel

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 mechanically • The BSPP is similar to NPSM connections with exception of the thread pitch, which that is different in most sizes.

British Standard Pipe Tapered

• 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.

Eaton Weatherhead Training Series Hose & Thread Identification

JIC

: SAE J514 37 Deg Flare This 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)

Eaton Weatherhead Training Series Hose & Thread Identification

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)

Eaton Weatherhead Training Series Hose & Thread Identification

Metric

: DIN 3902 Series This connection style consists of a common male and three different female halves.

The male has several features: 1) a straight metric thread 2) a 24 degree included angle 3) a recessed counterbore that matches the tube O.D.

The female has several configurations: 1) a tube, nut and ferrule 2) a tapered nose/globeseal 3) a tapered nose/globeseal with an o-ring

Eaton Weatherhead Training Series Hose & Thread Identification

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.

Eaton Weatherhead Training Series Hose & Thread Identification 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 Pipe

Step 1 Measure the thread pitch

• Holding 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.D

Using the caliper, measure the O.D. of the male thread or the I.D. of the female thread.

Step 3 Measure the angle of seal

• Using 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
