How to Select the Right Hydraulic Hose

A Hydraulic Hose is meant to transmit pressurized fluids to machinery, but choosing the proper hose and hydraulic hose fittings is crucial before purchasing. this will be done through using the STAMPED method.A mechanism is merely as strong as its weakest hose, which suggests selecting the proper one for your ship could make the difference between operating an efficient ship and handling a defective system.On the surface, hoses look relatively simple and possibly even interchangeable. actually , hoses are multi-layered, sophisticated tools designed and made for specific applications. deciding which hose is true for your system depends on several key factors, including size, temperature, compatibility and selecting the proper hose fitting connection


When selecting a replacement assembly, it’s important to think about both the ambient temperature and therefore the media temperature. The ambient temperature is that the temperature round the hose where it’s getting used . The media temperature is that the temperature of the media conveyed through the hose. The hose that’s selected must be ready to withstand the minimum and maximum temperature of the system.Hoses got to be ready to accommodate two temperature areas that of the hydraulic fluid which of the environment during which the hose exists (ambient temperature). Hoses that aren’t designed to face up to both the minimum and maximum temperatures of the fluid, also as those not designed to figure near hot manifolds, are likely to fail.Temperature conditions of the fluid also as in some cases the surface temperature is additionally vital. The temperature condition of the fluid will assist you choose between our wide selection .All of our hoses are supported application. they’re designed to be perfect for a group of features. this is often why we’ve a good range. A hose specifically designed for steam, oil, water, gas, fuel etc


For a hose to function optimally, its inside diameter must be large enough to accommodate hydraulic fluid, minimize pressure loss and avert heat generation or excessive turbulence, both of which may damage the hose. within the hydraulics industry, the “Dash Numbers” measuring instrument is employed to point hose size and therefore the proper accompanying couplings.In order to take care of optimum function, the within diameter of the hose must be large enough to accommodate hydraulic fluid, whilst minimising pressure loss. This lowers the warmth generated by the losses, and reduces the turbulence. many of us within the industry recommend employing a Dash Numbers/Dash Sizes measurement to spot the dimensions of the hose fitting. This measurement is that the inner diameter in sixteenths of an in. .The most important element while you’re trying to find your hydraulic hose. the dimensions of the hose play a really important role.To optimise your process, the inner or inside diameter has got to be large enough to let the fluid undergo it without obstruction. If there’s an obstruction within the passage, it’ll cause loss of energy / pressure and damage your hose.All other parameters will largely depend upon the dimensions of the hose, just like the pressure rating, end fittings, flexibility etc.

Pressure Rating:

This is the most important thing you should look for in the hydraulic hose. The pressure of the fluid that will be passed through the hose. It is very important.If you choose a hose pipe with a higher pressure rating, it will not cause much of a problem. Your problem will begin if the pressure in the fluid is more than what the hose can sustain.Every hydraulic hose will have two things, working pressure and bursting pressure. You can check out our technical specification under each product and find the ones that meet your pressure requirements.We always advice that you should consider working pressure while purchasing your hose pipe because the life of usage depends on it. A higher working pressure will drastically reduce the working life of your hose.

Compatibility :

Generally, replacement hoses should be duplicates of the first hoses. However, there are circumstances when employing a different sort of replacement hose is desirable. this is often very true if the hose failed prematurely thanks to excessive abrasion, unusual mechanical loads, routing challenges, temperature fluctuation or another environmental factor. With advancements in hose engineering, there could also be a far better hose available.As mentioned previously, a typical hydraulic hose consists of multiple tubes, including one inner, one outer and a number of other reinforcement layers. Since the hose tube must are available direct contact with the fluid it carries, the tube should be compatible with the system’s fluids to perform reliably. Furthermore, the threads and mechanical interfaces of ends and couplings got to be compatible with the hoses and other system components. If they’re not, leaks and other hose failures can occur.

Inside diameter:

It’s vital to use a hose of the right inside diameter. If the diameter is just too small for a given rate of flow, the linear velocity are going to be too high. Excessive velocity will translate into friction and turbulence, which when combined will surely end in noticeably higher system pressure and warmth .Hose manufacturers typically supply a table that permits for the straightforward calculation of the optimum diameter for a given flow and hose length. Long hose lengths require a bigger inner diameter to avoid excessive restriction and friction.


Flexibility means the bends that you simply require for your hose to satisfy . This variable is roofed altogether technical specifications under the bend radius heading.This metric informs what proportion are you able to hose bend, in other words it’s the pliability f the hose. The “U” shape that’s formed is measured for this calculation.If you are doing not have much space and sharp bends, it’s the time where you’ll decide if you would like to travel ahead with R13 or 4SH, teflon straight or convoluted.Flexibility may be a vital element, as we all know that the majority of the time, hydraulic hoses will tend to maneuver around with the machines. it’ll enter the direction and provides the power of the machines to be flexible.We do understand the importance of flexibility and the way important is it for the hose to sustain the load and pressure on the bends. Therefore, we sell only highest quality products which you’d know if you see the brands we provide . Quality is one among our driving factors and that we don’t compromise thereon .


Next, consider the conditions that a hose will operate under. The outer layer or cover of a hose can are available a spread of rubber materials. Some compositions can help with applications where abrasion may occur but might not bend as readily. Neoprene is one popular synthetic cover material that is still flexible across a good range of temperatures, yet handles abrasion well. Most rubber hoses perform reasonably well from –40°C (–40°F) to 100°C (212°F). search for the date of manufacture code on any rubber hydraulic hose that you simply are considering. the utmost time period is usually ten years at the foremost .


Ends of couplings must be properly matched to their components, to ensure that the connection is leak-proof. Do not mix ‘n match! It is recommended that you choose couplings that are of the same manufacturer as the hose. Hoses and couplings vary between manufacturers, and so mixing manufacturers can lead to assembly failure. Identify the type of threads used by the system, and then choose couplings that are compatible with those types of threads. Determine the seat type: thread interface, O-ring, mated angle or mechanical joint, mated angle with O-ring. Visually identify, and then measure threads.


Determining the quantity of fluid that’s getting to undergo the hose helps to work out the dimensions of hose that you simply got to use. If you select a hose that’s too small, it can cause increased pressure loss. Choosing a hose that’s overlarge will cause unnecessary costs and weight.
