How to Choose the Right Fluid System Hose for Your Application
Choosing the right hose is essential to achieving safe, reliable, and efficient fluid system performance. Because hose requirements vary based on application conditions, understanding key selection criteria can help improve system longevity, reduce maintenance concerns, and minimize the risk of premature hose failure. In this video, you'll learn general guidelines for selecting the appropriate hose based on factors such as operating pressure, temperature, media compatibility, flexibility requirements, and environmental conditions. You'll also gain an overview of common hose construction options, including rubber, nylon, PTFE-lined, silicone-covered, and metal hose designs, and the applications for which they are best suited. Understanding these differences can help ensure optimal performance and safety.

One question that comes up quite regularly is, “How do I select the proper hose for my application?” Well, the right answer to that is actually application specific. However, there are some general guidelines that we can provide to help you with your hose selection.
Let’s start with the most general service applications of air, oil, and water. Swagelok’s general service line is our rubber hose, our PB series, that features a Buna-N inner core, fiber reinforcement, and push-on end connections for ease of installation.
If you need a little higher pressure, consider Swagelok’s nylon core hose. Swagelok’s nylon inner core hose features a crimped end connection for higher pressure applications.
For applications requiring more chemical compatibility, Swagelok has a wide variety of PTFE inner core hoses with additional features according to your system requirements, from a smooth-bore stainless steel braid hose to a convoluted bore stainless steel braid hose for more flexibility.
If the stainless steel braid is a problem for your application, Swagelok offers the same hose, a smooth bore or convoluted core, with a fiber reinforcement.
If an easy-to-clean cover is a critical application requirement, Swagelok has two hoses with a silicon cover. One of the hoses has an additional insulation layer for thermal applications.
For the more critical, severe service applications, Swagelok has four offerings of all metal, stainless steel braid hose from 1/4 in. up to 2 in. for vacuum applications to 6000 PSI.
