When using hydraulic tools, many accessories are required to be used together. So do you know what common accessories there are? Generally speaking, these commonly used accessories include hydraulic hoses, digital impact sockets, quick coupler, square sockets, silicone oil shockproof pressure gauges, hollow sockets, adapters, etc.

Now, TorcStark will detail these accessories.

Hydraulic hose

At TorcStark, hydraulic hoses are mainly used to connect hydraulic wrenches and wrench pumps, bolt tensioners and tension pumps, hydraulic cylinders and jack pumps, etc. The oil output by the hydraulic pump is input into the corresponding tool through the hydraulic hose to fasten the bolt or lift the heavy object.

The hydraulic hose is mainly composed of nylon tube, polyurethane wrapped polyamide fiber, and steel wire reinforcement, which can pass water, oil, and other media. When the hose is high pressure, the hydraulic hose can transmit power safely, and its bend is very small, and easy to store and use.

Other applications of hydraulic hoses include mine hydraulic supports, oilfield mining, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and mechanization of various industrial sectors. Transportation of petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, and water) with certain pressure (higher pressure) and temperature in automated hydraulic systems wait.

Digital impact socket

Digital impact sockets are mainly used in hydraulic wrenches to tighten bolts by mounting them on hydraulic wrenches. The biggest difference between the digital shock socket and the normal socket is whether the torque value can be displayed. Digital impact sockets measure and display peak torque values and can be used to test hydraulic tools in place of torque calibration equipment. Moreover, the saved data can be read after the mobile phone or computer is connected to the sleeve via Bluetooth. In terms of accuracy, the torque accuracy of the digital impact socket is as high as ±1%.

A digital impact socket is not a must-have accessory for hydraulic tools, but if you are using it for torque calibration of hydraulic wrenches, it is an excellent replacement for torque calibration equipment. It has the advantages of lightweight, high precision, convenient movement and simple operation.

Quick coupler

At TorcStark, quick couplings are mainly used to connect hydraulic hoses and pumps, plate thicknesses, tensioners, hydraulic jacks and other equipment.

The quick coupler is used in combination with two, including a female coupler mother body, a through hole is arranged on the mother body, and a steel ball is embedded in the through the hole. The male coupler cylinder is provided with a groove and a clamping sleeve on the surface of the cylinder. When in use, the female coupler body and the male coupler cylinder are sealed and matched, the steel ball on the mother body is clamped into the groove on the surface of the cylindrical body, and the male and female coupler are tightly connected by threads.

The use of quick coupler saves time and effort. When disconnecting and connecting oil circuits through quick coupler, the action is simple, saving time and labor. When the oil circuit is broken, the one-way valve on the quick coupler can close the oil circuit, and the oil will not flow out, avoiding the loss of oil and oil pressure. Large equipment or hydraulic tools that need to be portable can be disassembled and transported using quick coupler, and then assembled and used after arriving at the destination.

Square socket and Low profile socket

These two sockets are mainly installed on hydraulic wrenches to tighten bolts of different specifications. Hydraulic wrenches adapt to different diameter bolts or nuts by changing sockets. The hydraulic wrench socket is made of high-strength chromium-molybdenum alloy steel, forged and formed, with reasonable and uniform hardness and high precision, which can effectively reduce the wear of bolts. Through standard heat treatment, the quality of the socket is better, safer, more reliable and more durable. . TorcStark offers custom non-standard wrench sockets and can manufacture the right socket for your actual needs.

Silicone oil filled shockproof pressure gauge

In TorcStark, the silicone oil shockproof pressure gauge is mainly used to install on the hydraulic pump to measure the output pressure of the hydraulic pump. The pressure gauge has good shock resistance, especially in the case of strong mechanical vibration and violent pulsation of medium pressure.

The silicone oil anti-vibration pressure gauge is composed of a pressure guiding system (including joints, spring tubes, current limiting screws, etc.), a gear transmission mechanism, a number display device (pointer and dial) and a shell (including watch case, watch cover, watch glass, etc.) . The case of the watch is an air-tight structure, which can effectively protect the internal parts from environmental influences and contamination. The damping fluid (usually silicone oil or glycerin) is filled in the shell of the watch, which can resist the vibration of the working environment and reduce the pulsation of the medium pressure.

Silicone oil shockproof pressure gauge can also be used in heavy machinery, mining, petroleum, chemical, metallurgy, electric power and other industries.


Adapters are accessories used to connect hydraulic hoses and quick connectors. The high-strength pressure that the adapter can withstand ensures the normal operation of the hydraulic system. adapters are widely used in hydraulic piping systems in military industry, energy, petrochemical, electric power, ships, automobiles, rail transit, construction machinery, mining, metallurgy, steel mills, marine engineering and other industries.
