The reinforcement layer provides strength to the hose and helps maintain its structural integrity, especially under high pressure. This layer is usually made of textile fibers or braided steel wires, which give the hose its flexibility and the ability to withstand pressure.

Outer Cover: The outer cover of the welding hose serves as a protective layer, guarding the inner layers from external factors like abrasion, heat, and sunlight. This layer can be made of synthetic rubber or a combination of synthetic rubber and plastic materials. It's designed to resist cracking, melting, and other damage that could be caused by the harsh welding hose manufacturers conditions of welding environments.

Color Coding: Welding hoses are often color-coded to differentiate between different gases and their specific use. For example, oxygen hoses might be green or black, while acetylene hoses might be red. This color coding helps prevent mix-ups and ensures safe usage of gases.

Reinforced Cord: Some welding hoses may include an additional layer of reinforced cord in between the inner tube and outer cover. This cord provides extra strength and stability to the hose.
