What is SAE male?

SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve. 7/16 – 20, 1/2 – 20, 3/4 – 16 & 7/8 – 14 are the same thread form as JIC 37° flare. Some fittings in these sizes have both JIC 37° & SAE 45° seats.

What is SAE hydraulic fittings?

SAE(SAE J512)stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It's common for copper tubes to be used with SAE threads. SAE Flare The SAE male and female halves both have a 45° flare seat.

Is SAE the same as NPT?

What's the difference between SAE & NPT threads? The biggest difference is SAE is a straight thread, it needs additional O-ring, gasket or sealing surface to form a seal; NPT thread is a taper thread, it can form a seal using its thread pitch.

What thread type is SAE?

SAE Thread Type – Straight Thread O-Ring Boss

SAE - Society of Automotive Engineers - straight threads are able to seal because of the 90-durometer Buna-N “O” Ring. This is a highly reliable and reusable thread type.

What is a SAE port?

A threaded hole and stud system that may be used to attach fittings to a component or manifold. Sealed with an o-ring or gasket.

Issue with SAE connectors - reverse polarity

What is SAE nuts and bolts?

SAE Bolt Grades—The standards for bolt strength grades in the U.S. are set according to a system developed by the SAE (Society of Automotive Engineers). The SAE marking system uses raised dashes on the bolt head to indicate strength.

ARE AN and SAE fittings the same?

The SAE went on to adopt this JIC standard as well. It's important to note that the AN and JIC specifications are no longer in existence in most cases. The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

Is SAE thread the same as UNF?

There are two general types of SAE bolts (sometimes referred to as machine screws). UNF (fine thread pitch) has more threads per inch than the same diameter bolt in the UNC (coarse thread pitch). Nut dimensions are maximums per SAE.

What are SAE threads used for?

SAE stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It's common for copper tubes to be used with SAE threads. The SAE male and female halves both have a 45° flare seat.

How is SAE thread measured?

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 mea- surement to the charts. Measure the thread diameter with an I.D./ O.D.

Are SAE and JIC fittings interchangeable?

SAE and AN/JIC fittings are completely incompatible due to the different flare angle. Furthermore, AN fittings (or those complying with subsequent standards) and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.

Which is the male fitting?

The terms Male and Female always refer to the threads on the fitting. Which is which? Male threads are on the outside, like a bolt. Female threads are on the inside, like a nut. The male threads screw into the female threads.

What is JIC hydraulic fitting?

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.

Is UNF same as NPT?

Most North American hydraulic and pneumatic components are compatible with National Pipe Threads (NPT), or Unified Threads (UN/UNF).

What is UNF and NPT?

UNF is Unified Fine thread, the successor to the obsolete National Fine (NF) thread. UNEF is Unified Extra Fine thread. UNS is Unified Special thread. UNJ is Aerospace inch threads – ISO 3161. NPT National pipe thread is used (in the U.S.) for plumbing of water and gas pipes, and threaded electrical conduit.

What is the difference between SAE and USS?

USS are coarse threads, while SAE are fine threads. Check your state and local codes before starting any project. Follow all safety precautions. Every effort has been made to ensure the accuracy and safety of this information.

ARE AN fittings NPT?

NPT (or National Pipe Taper) is a U.S. standard for tapered threads widely used on pipes and fittings for over 100 years. NPT connections rely on thread deformation- a metal to metal sealing design where the threads of the connectors themselves form together.

How do you identify an fitting?

You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).

What is SAE vs metric?

SAE & Metric: What's the Difference? SAE sockets are sized in inches and fractions of inches. Metric and SAE wrenches have different systems of measurement. Metric sockets and wrenches use the metric measurement system.

What does SAE metric mean?

SAE or Standard: A standard or SAE (Society of Automotive Engineers) wrench is measured in fractions of inches. Small wrenches will be around 1/4 inches, while large wrenches will be 1 inch or larger. Metric: A metric wrench will work with nuts and bolts that have a metric measurement.

How do I know if my threads are standard or metric?

Metric threads are measured by their pitch. That is the distance from the crest of one thread to the crest of the next measured in millimetres. The pitch of a metric thread can be checked by direct measurement with a metric rule. Imperial threads have their pitch measured indirectly as a given number of teeth per inch.
