How do I know what size hydraulic fittings I need?
How to Measure Your Hydraulic Fitting
- First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it.
- Next, determine the outside diameter of the fitting by using your ID/OD calipers.
How do I choose a hydraulic fitting?
Six Things to Consider When Picking the Hydraulic Fittings:
- The Security of the Connection Including Sealing Type. Be careful if you use NPT (National Pipe Taper) pipe threads fittings.
- Pressure Rating.
- Vibration.
- Temperature.
- Chemical Compatibility and Operating Fluid.
- Availability.
What fittings are used for hydraulic system?
The most commonly used fitting materials are brass, aluminum, steel, or stainless steel. NBR (Nitrile) O-rings are the most widely used sealing materials. Temperature: The hydraulic fittings should be suitable for your temperature range.

Are hydraulic fittings standard?
NPT hydraulic fittings: NPT (or National Pipe Taper) is a U.S. standard for tapered threads widely used on pipes and fittings for over 100 years.
Why is it important to select properly the size of pipes valves and fittings in hydraulic systems?
In many fluid power applications, energy losses due to flow in valves and fittings exceed those due to flow in pipes. Therefore,a proper selection of fitting is essential. In general, the smaller the size of pipe and fittings, the greater the losses.
How many types of hydraulic fitting are there?
There are two fitting types: permanent (crimped) and reusable (re-usable / returnable). In most cases, the crimped type of hydraulic hose is used because the second one is considered as the old-school one. New equipment requires a permanent type of fitting that is installed with the help of the crimping tool.
How do I choose an fitting?
Selecting Your Fittings
- Consider the Tubing Used. Barbed fittings work best with flexible tubing such as silicone or PharMed®.
- Determine Material Compatibility. Fluids that are incompatible with fitting material may cause leakage or system damage.
- Check Temperature and Pressure Conditions.
What size is #8 hydraulic fitting?
Hydraulic Hose Fitting: -8 For Hose Dash Size, 3/4 in x 1/2 in Fitting Size, JIC x Hose, Straight.
How do you size an fitting?
AN Fittings and Hose Sizes Chart
| AN Size | Hose / Tube O.D. | SAE Thread Size |
|---|---|---|
| -5 | 5/16 in. | 1/2 in.-20 |
| -6 | 3/8 in. | 9/16 in.-18 |
| -8 | 1/2 in. | 3/4 in.-16 |

What does JIC mean in hydraulic fittings?
Joint Industry Council
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.
How do you select hydraulic pipe for a hydraulic system?
Six Criteria for Hydraulic Hose Selection
- Size. Size, especially inside diameter, should be appropriate to remain pressure loss at a minimum level and prevent extremely high temperature and excessive turbulence.
- Pressure.
- Impulse pressure.
- Temperature.
- Chemical compatibility.
- Bend radius.
What type of pipe is used for hydraulics?
Steel pipes, copper pipes, stainless steel pipes, and rubber hoses are used in piping for hydraulic equipment. Copper pipes are not used in common practice because it accelerates oxidation of petroleum-based hydraulic fluids.
