The selection of additional components for the Pu Air Hose should be given equal importance as the selection of the hose. The specifications like pressure of the hose, material type, diameter of the hose, etc. plays an important role in the selection of these additional components for accident prevention.
Hose reels are designed to provide protection to the hoses. Modern hose reels are retractable and provide complete encasing to the hose. These hose reels also help eliminate loose uncoiled hoses on the shop floor and reduces the risk of accidental damage to the hose.
An air pressure gauge or gas pressure gauge allows the user to know the system's pressure. This is important to ensure the pressure doesn't excceed the aplication requirements or other product specifications.
Fittings for air and gas hoses should be able to withstand the pressure required for the application to run smoothly and safely. Generally, brass, type 304/316 stainless steel or zinc plated steel are used as the material for the fittings. The material of the fittings should be resistant to the corrosive effect of the gas. Figure 5 is an example of a brass hose connection fitting.
