PTFE (polytetrafluoroethylene) is a high-performance fluoropolymer, renowned as the "King of Plastics" owes its title to exceptional properties including corrosion resistance, high temperature resistance, non-sticky, low friction coefficient .Fabricated from pure PTFE or modified compounds, widely used in chemical, medical, semiconductor and other sophisticated fields, is the "invisible champion" in the industrial transmission system.
PTFE Hoses exhibit near-universal resistance to chemical media,including strong acids,alkali,and organic solvents,making them indispensable in chemical processing ,electroplating,and corrosive gas exhaust systems.
Stable across extreme thermal conditions—from cryogenic environments to high-temperature steam,PTFE hoses maintain structural integrity,ideal for high-heat fluid transfer and heating applications.
The smooth inner surface minimizes fluid resistance,enhancing energy efficiency and flow rates,particularly for high-viscosity fluids.
With low dielectric loss in high-frequency settings,PTFE Hoses are critical for high-precision applications like semiconductor equipment and high-frequency cable shielding.
The non-adherent surface prevents residue buildup.ensuring purity in pharmaceutical systems and ultra-clean chemical transport for semiconductor manufacturing.
Resistant to UV degradation,oxidation,and fouling,PTFE Hoses reduce downtime and extend service life in demanding outdoor and industrial environments.
Advanced PTFE hoses: Material Modifications Boost Performance in Complex Industrial Scenarios.
Enhanced compressive strength,suitable for high-pressure hydraulic systems.
Improved wear resistance,extends the lifespan of mechanical components.

The hose matches the flow rate to ensure effective transmission efficiency.
Flanges, clamps, welds and other joints should be matched to your equipment
In the era of industry 4.0,PTFE hose is not only a breakthrough in material technology ,but also a strategic choice for enterprises to reduce costs and increase efficiency ,whether it’s to solve the pain point of corrosion discharge leakage,or to meet the stringent needs of semiconductor,medical and other high-end fields,which can easily be qualified,and redefine the standard of industrial pipes. This is not only an upgrade of engineering materials, but a revolution in industrial efficiency.
A hose can be defined as a flexible tube hollow from inside designed to carry fluids from one location to another. The shape of a hose is usually cylindrical which has a circular cross-section. Hydraulic hose is graded by pressure, temperature, and fluid compatibility.
Hoses are used when pipes or tubes can not be used, usually to provide flexibility for machine operation or maintenance. The hose is built up with rubber and steel layers. The exterior is designed for abrasion resistance. Careful consideration has been given while designing the bend radius of the hydraulic hose.
This is due to the fact that hose failures can be deadly. Hydraulic hoses generally have steel fittings that are held on to the ends. This is considered to be the weakest part of the hose and thus considerations should be given while installing or removing the fitting.
Hoses are made from one or in some cases many different materials. The most general material used to make a hose is nylon, polyurethane, polyethylene, PVC, or synthetic or natural rubbers, based on the environment and pressure rating needed.
Besides, Certain hoses on the basis of their applications can also be manufactured from special grades of polyethylene (LDPE and especially LLDPE). Other hose materials include PTFE (Teflon), stainless steel and other metals.
The hydraulic system pressure should not exceed the rated working pressure of the hose. Keep a check on the Pressure surges or peaks which exceed the rated working pressure as they can be destructive for a hose.
Burst pressures are pressures referred to in this catalog which were intended for destructive testing purposes and for design safety factors only.
Keep the hose safe from any internal or external temperatures exceeding the specified limits. Make sure to check the technical data when hydraulic fluids contain emulsions or solutions. The fluid manufacturer’s recommended maximum operating temperature for any given fluid must not be exceeded, regardless of the hose temperature range.
The hydraulic assembly (tube, cover, reinforcement, and couplings) must be fluid compatible. The correct hose must be used because phosphate ester and petroleum-based hydraulic fluids have drastically different chemical characteristics. Many hoses are compatible with one or the other but not all fluids. For example, Gates extreme Heat G2XH hose is capable of handling phosphate ester and petroleum-based hydraulic fluids.
Do not bend or flex hose to a radius smaller than the minimum recommended and do not subject hose to tension or torque. This can place excessive stress on the reinforcement and severely reduce the ability of the hose to withstand pressure.
Hose size (inside diameter) must be capable of handling the required flow volume. Too small an I.D. for a given volume of flow results in excessive fluid pressure and heat generation which can result in tube damage.
Make use of clamps to restrain, protect or to guide hose, and also to minimize the risk of damage because of any excessive flexing, whipping or any contact with other moving parts or corrosives. Determine hose lengths and configurations that protect from abrasion, snagging or kinking and provide leak-resistant connections.
The length of the Hose should include considerations for length in the case of any changes under pressure, hose assembly routing machine vibration and motion.
Select the proper hose for the application. Suction applications (Gates GMV or G4H) and special fluid or high-temperature capabilities are among the applications requiring particular consideration and a specific hose. When additional information is required, contact your local representative.
1. Establish a program of inspection, testing, and replacement of hose assemblies from factors including Severity of application, frequency of equipment use, past performance of hose assemblies.
2. Only properly trained persons should inspect, test or service hose assemblies. Update training periodically.
3. Avoid fuel injection injuries. Fluid under pressure can cause serious injury. It can be almost invisible escaping from a pinhole, and it can pierce the skin into the body. Do not touch a pressurized hydraulic hose assembly with any part of your body.
If fluid punctures the skin, even if no pain is felt, a serious emergency exists. Obtain medical assistance immediately. Failure to do so can result in loss of the injured body part or death.
