Tubing & Hose Buying Tips
#2: Pressure & Vacuum
It can be challenging to make sure you’ve covered all the bases during the tubing and hose selection process. Have you considered all the elements involved with the application? Temperatures, chemicals, pressures, flexibility needs? In Tubing & Hose Buying Tips we’ll address common selection factors, one at a time, in each issue of extrusions.
 This second tip focuses on pressure and vacuum requirements. Applications can range from simple drainage lines, well handled by gravity and involving virtually no pressure, to those requiring a robust product able to manage full vacuum (29.9 in./Hg.).
You’ll need to consider whether your application is one of these extremes or, more likely, one that falls in between. Some unreinforced tubing can deal adequately with low pressure situations; others cannot. It often depends on the tubing material and how hard or soft it is (i.e., polypropylene or latex).
Reinforced hose is frequently called for in pressure and vacuum applications. In fact depending on the type of reinforcement (braid, fabric, stainless steel wire, convolution), certain types of reinforced hose are well suited for pressure applications, while others are better for vacuum (see below). If you’re unsure of your application’s pressure or vacuum needs, you’ll need to ask questions, conduct tests, or find out from an informed source. Research the needs and usage to avoid situations where the tubing or hose ruptures – or even explodes – because it was not the right product for the application. Human injuries can occur depending on the severity of the rupture.
