Product Description
Rubber tubing is a tubular product primarily made from rubber, typically consisting of an inner and outer rubber layer along with a skeleton layer. It is used to transport gases, liquids, slurries, or granular materials. The core function of rubber tubing is to facilitate the transmission of media through its elastic sealing and pressure-bearing capabilities, and it is widely utilized in various fields such as industry, automotive, and medical treatment.
1. Introduction of rubber pipe material
crude rubber |
With high elasticity, wear resistance, bending and scratching characteristics, suitable for low pressure environment. |
Protobutadiene rubber (SBR) |
Excellent wear resistance, low cost, but poor oil resistance. |
cis-polybutadiene (BR) |
Good moisture resistance and outstanding low temperature resistance (still elastic at-50ºC). |
Nitrile rubber (NBR) |
Excellent oil resistance (resistance to mineral oil, lubricating oil), but weak ozone resistance and high temperature resistance. |
chloroprene rubber (CR) |
Oil resistance, ozone resistance, aging resistance, comprehensive performance balance. |
EPDM Rubber (EPDM) |
High temperature resistance (-50~150ºC), strong weather resistance, suitable for long-term exposure to the outdoors. |
fluorinerubber (FKM) |
High temperature resistance (-20~250ºC), chemical corrosion resistance, suitable for extreme environment. |
silastic (VMQ) |
High temperature resistance (-70~300ºC), high transparency, excellent electrical performance. |
Chlorinated sulfated polyethylene rubber (CSM) |
Resistance to strong acid and alkali (such as concentrated sulfuric acid, nitric acid), strong permeability resistance. |
conductive rubber |
Built-in conductive fibers or metal mesh to prevent static accumulation. |
Fire retardant rubber |
Add flame retardant (such as aluminum hydroxide), passed the UL 94 flame retardant certification. |
2.Structural composition of the rubber pipe
The glue layer |
Direct contact with the conveying medium, with wear resistance, corrosion resistance (such as oil resistance, acid and alkali resistance). |
casing pyl |
Enhance the strength of the tube body, including cotton thread, steel wire, synthetic fiber, etc., to determine the pressure bearing capacity (e. g., the steel wire woven layer can withstand 80~600MPa pressure). |
External glue layer |
Protect the internal structure from the external environment (such as ultraviolet light, mechanical friction). |
3. Structurally, rubber pipes are categorized into various types, including sandwich hoses, braided hoses, winding hoses, and full hoses.

Product Parameters
Working principle of rubber pipe
Pressure transmission and energy buffer |
The hydraulic hose transfers the force through the fluid pressure, and uses the elastic shape of the rubber to absorb the pressure pulsation, and reduce the vibration of the system. For example, the hydraulic pipe of construction machinery bears high pressure (up to 60MPa or above) through a multi-layer steel wire reinforced layer. |
Shock absorption and displacement compensation |
Rubber soft connection (e. g., flexible rubber joint) absorbs pipe displacement through the elastic deformation of the curtain layer and wire ring to reduce operating noise, which is suitable for pump valve connection and frequent vibration line. |
Media isolation and leakage prevention |
The compactness of the inner adhesive layer combines with the protection of the outer adhesive layer to prevent the leakage of water, gas or chemicals. For example, the mobility of the coolant between the car radiator and the engine. |
Application areas:
industrial circle |
Welding gas delivery, hydraulic system, mine ventilation. |
automotive filed |
Coolant circulation, fuel transmission, air-conditioning system. |
Medical field |
Infusion tube, surgical instrument catheter. |
The field of agriculture |
Irrigation system, aquaculture equipment. |
New energy field |
Automobile battery and wind turbine cooling system, etc. |
Standardization and security guarantee:
high-voltage insulation test |
Burst pressure is 3 times the working pressure (such as hydraulic hose). |
degradation testing |
Simulated high temperature / UV environment assessment life (theoretical value of more than 15 years). |
Environmental requirements |
Biological based rubber and low VOC (volatile organic compounds) formula meet the sustainable development needs. |
