Eaton Weatherhead Training Series Hose & Thread Identification Having the proper tools on hand, is a key contributor to successful thread identification. The FT 1341 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 Thread pitch gauge Reference Guide 2. A seat angle gauge 3. An I. D/O. D caliper 2 in 1 seat angle/caliper tool Use the reference guide to quickly convert your measurements into a part number Click Next >> to continue.

Eaton Weatherhead Training Series Hose & Thread Identification A thread pitch gauge is used to measure two types of threads: 1) Non metric: Number of threads per inch for non-metric connectors 2) Metric: Distance between threads for metric connectors Thread pitch gauge A seat angle gauge is used to measure the sealing surface of both male and female connectors. The caliper is used to measure thread diameter 2 in 1 seat angle & caliper tool Higher res images here Click Next >> to continue.

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 Click Next >> to continue.

Number of threads per inch for non metric connectors q B. Distance between threads for metric connectors q C. All of the above Submit

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 Manufacturer/ - Hose pressure rating Brand Hose Name - Hose I. D. (inner diameter) - 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 Click Next >> to continue.

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 J 514 37 Deg Flare (LINK TO SLIDE 20) ORFS: O Ring Face Seal SAE J 1453 (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 British Standard Pipe Tapered • • The BSPT male thread has tapered threads and a 30° inverted seat. The seal takes place by thread distortion. • 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. • 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 J 514 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 J 1453 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 thread pitch • Holding the fitting straight, place 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 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 * Step 4 • Refer 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” OD -06 JIC should be the 37 degree angle Click Next >> to continue.
