Choosing PVC BRAIDED HOSE 600PSI: Medium, Dimensions and Operating Conditions

1. What the product is built from

The published product description gives this construction:

• Tube and cover: PVC or rubber
• Reinforcement: high-tensile polyester braiding

The listing says the compound is either PVC or rubber. Ask which one applies to your order, because this choice can affect fluid compatibility and how the hose handles.

The description also says the hose is light, flexible, non-kinking and non-twisting. It calls the hose UV and ozone resistant and weather resistant, with a smooth outer surface. According to the listing, a four-season soft formula keeps the hose usable as the seasons change.

2. Medium: what the hose may carry

The listing names these applications:

• welding machines
• architecture and building work
• lacquer factories
• jackhammer hose use, and wind drilling hose use because the hose is flexible and resists damage

3. Pressure rating

The product text describes the hose as working under high pressure in a range of 300 PSI to 600 PSI. The published size table gives the same rating for every listed size:

• Working pressure (W.P.) at 23°C: 40 bar / 600 PSI
• Burst pressure (B.P.) at 23°C: 120 bar / 1800 PSI

These ratings are stated at 23°C. The source gives no derating for higher temperatures, so if your system runs hot, ask for pressure data at your actual operating temperature. Choose a hose whose working pressure covers the highest pressure your system reaches, including any surges. Do not plan to run the hose close to its burst pressure.

4. Temperature range

The stated working temperature is -20°C to +65°C. One note on the source text: it prints the Fahrenheit equivalent of -20°C as "-68°F". The correct conversion of -20°C is about -4°F, so confirm the intended low-temperature limit with the supplier. The upper limit of +65°C is given as +150°F, which matches a standard conversion.

5. Dimensions: choosing a size

The published size table lists nine sizes. All are rated 40 bar / 600 PSI working and 120 bar / 1800 PSI burst at 23°C.

Things to check when choosing a size:

• Match the inner diameter (I.D.) to your fittings, not just the nominal inch size. The 5/16" size comes in 8 mm and 8.5 mm I.D. versions. The 3/8" size comes in 9.5 mm and 10 mm versions. Quote the I.D. and O.D. in millimetres when you order.
• Check the outer diameter (O.D.) when the hose has to fit clamps, guides or reels.
• Use weight per metre to estimate handling effort and shipping weight for long runs. For example, the table lists 110 g/m for 1/4" and 630 g/m for 1".

6. When this hose is not the right choice

Based on the published data, look for a different product or get further confirmation if:

• your working pressure is above 40 bar / 600 PSI, or you need ratings above 23°C that have not been published
• your operating temperature is below -20°C or above +65°C
• you need an I.D. smaller than 6 mm or larger than 25 mm, which are the limits of the published table
• you need compatibility with a specific medium, or a certification for your market.
