Common Types of Reinforcements Found in Hoses


Most hoses are made up of three elements: tube, reinforcement and cover. Hose reinforcement is built in between hose tube and cover and act as a control for:

·         Axial and radial forces Pressure capabilities· Kink resistance

·         Strength and durability

·         Longevity

·         Flexibility

Hose reinforcement can come in different materials such as textile, plastic, metal or the combination of them.  It also has different shapes and forms such as braided or spiraled wire, braided or spiraled textile, cable and metal or plastic helix depending on requirements.

Some common reinforcements types:
1.       Yarn and Textile

Yarn Reinforcement

Figure 1 Picture of yarn-reinforced PVC hose.

Yarn reinforcement is built with fiber. Some example of the fiber used are aramid, cotton, glass, nylon, polyester etc. The yarn will then be weaved and built onto the hose to provide support
2.      Helical Spring

Plastic Helical Spring

Metal Helical Reinforcement

Figure 3 Picture of Metal Spring Wire Reinforced Hose

Helical spring wire uses a long wire that is helically wrapped into the hose. The wire can come from either plastic or metal such as PVC, Stainless Steel, etc.
3.      Piles of Steel Wire Cords

Plies of weaved wire cord is built into the hose creating multiple layers of reinforcement.
4.      Metallic Braids

Metallic Braid

Figure 5 Metallic Braid Reinforcement

Several steel wires are interwoven to form metallic braid. The braid will then coat the tube and give additional strength and protection. Metallic braid can come in different materials from bronze, stainless steel etc.
5.      Combination


Figure 6 Picture of Hose with Yarn and Spring Helix Reinforcement

Some hoses use and combine multiple reinforcements to create hoses with an improved property. The picture on the left shows a hose with both yarn and helix wire reinforcement.
6.      No Reinforcements

No Reinforcement

Figure 7 Non-Reinforced Hose

The Left picture shows a non-reinforced hose made from Silicone. This type of hose uses no reinforcement. Examples: Tubing.

Are You Using the Right Rubber Hose?

Rubber Trees

Using the right hose for the wrong application can be very costly because it may risk the safety of your workers and damage the equipment. This article will help you avoid the same mistakes made by other users and teach you how to choose the right rubber hose for the right application.

An industrial hose is always identical to rubber. Rubber is a polymer, either natural or synthetic, that can be shaped in high temperature (thermoplastic) and has high elastic modulus; meaning it can retain its original form when deformed. This elastic material has been used for hose construction due to its versatility in fluid transfer. This versatility is obtained from the wide variety of rubber types available. Since each type has its unique properties, it creates more opportunity to convey more chemicals.

There are plenty of rubber types on the market. The most commonly used are Natural Rubber (NR), Styrene-Butadiene Rubber (SBR), Nitrile Rubber (NBR), Ethylene Propylene Diene Monomers Rubber (EPDM) and Neoprene/Chloroprene Rubber (CR). For this article, we will base our discussion solely on these 5 types. Each of them has unique traits that make them applicable to a specific application. It is advisable to contact your salesperson to find the right rubber hose.


The table below summarizes the entire advantages and disadvantages of different rubber hoses.

Rubber Types Code Advantage Disadvantage Application
Natural Rubber NR 1. Excellent Physical Property
2. Excellent Abrasion Resistant
1. Poor Oil Resistant
2. Low Operating Temperature Range
1. Bulk Material/dry material Hose.
Styrene-Butadiene Rubber SBR 1. Good Physical Property
2. Good Abrasion Resistant
1. Poor Oil Resistant 1. Utility Hose (Air & Water).
Ethylene Propylene Diene Monomer EPDM 1. Excellent heat, ozone and weathering Resistant
2. Excellent steam resistant
3. Excellent acid & caustic resistance
4. High Operating Temperature Range
1. Poor Oil Resistant 1. Hose Cover.
2. Steam Hose.
Nitrile Rubber NBR 1. Excellent oil resistance
2. Good physical properties
1. Poor Weathering Resistance 1. Fuel Transfer Hose.
Neoprene CR 1. Excellent weathering resistance
2. Flame Retardant
3. Good Oil resistance
4. Good Physical Properties
1. Hose Cover.

Personal Take Away

As a personal rule of thumb, NBR is always the first choice for oil transfer hose; EPDM is mostly used for hot water/steam hose; NR is the best choice for dry material hose; Neoprene is good for its fire-retardant property; SBR is mostly used for utility transfer hose.
