Hydraulic Hoses Compact Steel Wire Braided HCH Series
Hydraulic Hoses Compact Steel Wire Braided
HCH Series
Introduction
HCH Series Compact Steel Wire Braided Hydraulic Hoses are design with a synthetic rubber core for oil base or water base fluids. They feature
multiple layers of high-tensile steel wire braiding for reinforcement, along with a weather-resistant, oil-resistant synthetic rubber cover. This construction provides excellent high-pressure resistance and a minimal bend radius. These hoses are primarily used with oil-based liquids such as hydraulic oil, gasoline, diesel, lubricating oil, as well as biodegradable hydraulic fluids, fire-resistant synthetic polyol esters, and other similar media.
Features
◎ Cover: Weatherproof, oil-resistant synthetic rubber
◎ Reinforcement: Double-layer of high-tensile steel wire braid
◎ Core tube: Synthetic rubber for oil based or water based fluids
◎ End connection material: Stainless steel
◎ Nominal hose size: 1/4″ to 2″
◎ End connection sizes: 1/4″ to 1″ and 6 mm to 25 mm
◎ Working pressure up to 5800 psig (400 bar)
◎ Working temperature: -40°F to 212°F (-40°C to 100°C)
Hose Technical Parameters
Testing
Every FITOK hydraulic hose assembly is factory tested with pure water at 2 times the maximum working pressure.
Cleaning and Packaging
FITOK hydraulic hose components are cleaned in accordance with FITOK Standard Cleaning and Packaging Process (FC-01).
Shorter hoses are packed in cartons with suitable protective material, longer hoses are coiled, bagged and boxed or crated.
Knowledge refences :
Note: “Ordering Number Description” is a reference to understand the combination rules of FITOK product part number.
Not all combinations are available.
Example: SS-HCH4-FL4-NS4-F36
SS: End connection material is 316 stainless steel
HCH4: HCH series, nominal hose size is 6.4 mm
FL4: End connection 1 is 1/4″ tube fitting
NS4: End connection 2 is 1/4″ male NPT
F36: Overall length is 36″
Connections are described based on the following rules:
1. Metric Tube Fitting – Fractional Tube Fitting – Metric Tube Adapters – Fractional Tube Adapters –
NPT Threads – BSPT Threads – BSPP Threads – SAE/MS Parallel Threads – 37° Flare – Others
2. Put the sizes from the biggest down to the smallest if they are of the same type.
3. Put the female before male if they are of the same type and size.
Hose & Fitting Failure
While rare, it is possible for a hose or fitting to fail under pressure.
Hose or fitting failures can have a number of different causes.
To avoid failures, replace hoses as soon as there are any signs of fatigue, cracking, blistering or there are any signs of the hose slipping out of a crimped fitting.
A failed hose can strike at high velocity resulting in injury or even death as a pinhole leak can easily pierce the flesh or damage an eyeball!
