In daily life, hoses can be seen everywhere, and they are even filled in every corner of our lives. When choosing hoses, we are more inclined to choose hoses with high cost performance and good quality. So, how should we choose high-quality hoses? What are the characteristics of high quality hoses? Next, let’s explore it!
1、 Check the material of hose
Times are changing, technology is progressing, and various types of hoses have also been introduced into the market. For example, stainless steel hose, nylon hose, corrugated hose, plastic hose, etc. What are the characteristics of hoses made of different materials?
Stainless steel hose
It mainly refers to the hose made of 304 stainless steel or 301 stainless steel, which is resistant to high temperature and abrasion, has good flexibility, corrosion resistance, tensile resistance and waterproof, and provides a certain explosion-proof effect.
Stainless steel braided hose
Stainless steel shower hoes
Nylon Braided Flexible Hose
It is mainly made of PET nylon fiber, which has the characteristics of high toughness, high impact resistance, good bending performance, high temperature resistance, bright surface, friction resistance, chemical corrosion resistance, flame retardancy and electrical insulation.
Nylon Braided flexible hose
PVC flexible hose
It is generally made of synthetic resin (polyester) as raw material, and extruded in the pipe making machine by adding stabilizer, lubricant, plasticizer, etc. It has the characteristics of light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction.

2、 Check appearance of the hose
When we purchase flexible hoses, we must first focus on whether there are any defects on the hose surface. Therefore, the good or bad appearance of the hose can directly determine the quality of the hose, and to a certain extent, the good or bad appearance will even affect consumers’ purchase desire. For example, when purchasing a stainless steel metal shower hose, be sure to check whether its stainless steel outer surface is flat, whether the gap is evenly distributed, and whether it feels smooth and does not sting.
When purchasing braided hoses (including nylon braiding and stainless steel braiding), the weaving effect must be observed. The weaving must not have such undesirable phenomena as jumping, breaking, and overlapping, and the higher the weaving density, the better. Then how to see the density of braided hose is to see whether the gap and diameter between each strand of silk and the braided pattern are smooth and even.
In addition to the external surface of the tube body, the appearance of the connectors at both ends of the hose shall be checked to see if there are any defects. The connector surface shall be free of stains, oxidation and damage, because these defects may even affect the installation effect of the hose to a certain extent.
3、 Check the material of the inner tube
In daily water use, both hot and cold water need to pass through the hose, so the material of the inner tube is very important. On the market today, the inner tube is mainly made of PVC, PE, silica gel and EPDM. Why do you choose these materials for the inner tube? What are their characteristics and similarities?
PVC is the abbreviation of Polyvinyl chloride. Its main component is polyvinyl chloride. It is a material that enhances its heat resistance, toughness and corrosivity by adding other components. PE is the abbreviation of Polyester, which is mainly composed of polyethylene. It is a non-toxic, harmless, ductile, corrosion resistant, aging resistant, high temperature resistant and low temperature resistant material. Silica gel is a new non-toxic, harmless, high polymer elastic material with excellent performance of high temperature resistance, low temperature resistance, aging resistance and corrosion resistance. EPDM, also known as EPDM, is a copolymer of ethylene, propylene and a small amount of non conjugated dienes. It is a material with low density, toughness, aging resistance, corrosion resistance and heat resistance. It can be seen that they all have the properties of heat resistance, aging resistance and corrosion resistance.
Nowadays, in the market, the ordinary shower hose is made of EPDM, and the inner pipe is best made of PE. Compared with the other three materials, this material has the advantages of outstanding aging resistance and heat resistance, is not easy to expand and deform, and has good toughness, shrinkage, and smooth feel. Therefore, you can pay special attention to this when selecting hoses.
4、 Check the certification certificate of the hose
What is certification? “Certification” refers to the activity of a third-party organization with professional capabilities to prove that products, services, management systems and personnel conform to relevant standards and technical specifications. It is an internationally accepted means of quality management and trade facilitation. It can prove that the product will not change the sense, chemical composition and microbial characteristics of water. The more certificates passed, the more it can prove that this hose is safer and healthier for water quality.
Therefore, when we choose hoses, we will prefer to choose products with certification marks, because with these certifications, it is equivalent to proving that this product is safer to use, more reliable in quality, and provides a favorable guarantee for our daily water use. The main sanitary certification in the world are:
UPS, CE, WRAS, ASC, DVGW, WATERMARK, etc.
