How do I know what size hydraulic hose I need?
In the vast majority of common hydraulic hoses, the I.D. measurement is divided into 1/16” increments known as the “dash size.” For example, a hose measuring 3/4” ID will be shown as a “-12” coming from the numerator of the fraction of 3/4″=12/16”. A 1” ID would be 16/16 or a -16, and so on.
What size is a hydraulic fitting?
Hydraulic Fitting Dash Sizes The expression of fitting connection size is typically in dimensionless terms representing 1/16 of an inch. For instance, if someone calls out a “-0.6 thread,” they man the size is 3/8 or 6/16 of an inch. A “dash 32” size is a 2 inch connection or 32/16 of an inch.
What size is a 4 hydraulic hose?
How to Interpret Hose, Tube & Fittings “Dash Sizes”
| HOSE I.D (Inches) | ||
|---|---|---|
| All EXCEPT Transportation & Refrigerant Hoses | Transportation & Refrigerant Hoses | |
| -4 | 1/4 | 5 |
| -5 | 5/16 | 6,3 |
| -6 | 3/8 | 8 |
Is standard for hydraulic hose?
The ISO 18752 Standard has nine pressure classes for maximum working pressure, ranging from 500 to 8,000 psi. Hydraulic hoses meeting ISO 18752 specifications are classified according to their resistance to impulse pressure in four grades: A, B, C, and D.
What is the difference between 2 wire and 4 wire hydraulic hose?
Hydraulic hoses are rated for different pressures, temperatures, fluids and/or environments. For example, R2T hose has 2 wire braids and is commonly used for low to medium pressure hydraulic fluid. 4SP hose has 4 wire braids in within the rubber and is capable of higher pressures.
Does hydraulic hose size affect flow?
Size. The hose I.D. must be sized accurately to obtain the proper flow velocity. A flow that’s too slow results in sluggish system performance and a flow that’s too high causes excessive pressure drops, system damage, and leaks.
How do you identify hydraulic hose threads?
There are six types of threads commonly used on hydraulic tube fittings: UN/UNF….Four Steps to Thread Identification
- Step 1 – Determine if the thread is tapered or parallel.
- Step 2 – Determine the pitch.
- Step 3 – Determine the size.
- Step 4 – Designate the thread.
What does a JIC fitting look like?
JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.
How do I choose a hydraulic hose?
When choosing a hose you should consider the pressure rating, temperature range, cover material and bend diameter among other factors. Before assembling a rubber hydraulic hose, clean it internally! Use brackets and supports wherever required to maintain the best hose position, and to avoid unnecessary flexing.
What is the id of hose?
Inner diameter
Inner diameter (I.D.) is the span of the empty space in a circular hose cross-section that affects the flow velocity of the fluid within the hose.
What is standard hydraulic hose?
SAE standards provides general, dimensional and performance specifications for the most common hoses used in hydraulic systems on mobile and stationary equipment. The majority of hydraulic machines are not exotic, and typically your standard 100R1 or 100R2 (“1-wire” and “2-wire” respectively) hoses are appropriate.
How much psi can a garden hose handle?
The PSI rating on garden hoses is the amount of pressure the hose can safely handle. Lower-quality hoses are rated around 200 PSI, and high-quality hoses can be rated up to 600 PSI. If you’re looking for a hose this durable, check out zero-G hoses! These hoses can withstand a PSI rating of up to 650!
What kind of cover do I need for a hydraulic hose?
Meets or exceeds SAE 100R16 performance specifications. Tube: Black, oil resistant, Nitrile (NBR). Reinforcement:Two wire braid of high tensile steel. Cover: Black, oil and abrasion resistant Neoprene (CR).
What are the different types of cat hose assemblies?
Cat Hose Assemblies are available in a broad line of high, medium and low-pressure options, and are engineered and tested far beyond industry standards for top performance and long life. Cat ToughGuard™ hoses feature a highly abrasion-resistant polyethylene cover that has surpassed two million cycles of abrasion testing without failure.
What does the part number on a cat hose mean?
Each Cat hose assembly has a part number on a label or tag. This enables easier ordering of a replacement hose assembly built to same-as-new specifications. You will see a wide range of assemblies listed, including all of our popular hydraulic hose assemblies.
