The XHose holds up to 500 PSI, and when filled with water flowing, the hose had some pliability and its spray was less powerful than the zero-G hose. The XHose does not come with a sprayer, so you'll need to purchase one separately.

This can be measured in mm (mm/Hg) or inches. 750 mm/Hg is regarded as full vacuum which would indicate a complete absence of pressure inside the hose. Most commercial pumps would not develop a full vacuum and 625 to 700 mm/Hg would be about the limit.

Temperature rating for these flexible rubber hoses is -65F° to 275F°. For an additional clear rubber hose option, see the static dissipative urethane hose.

In the U.S., the common standard to measure rough vacuum is inches of mercury ("Hg), which can be measured in two different ways. One method is as "Hg gauge ("HgV), where the scale starts at 0" Hg (atmospheric pressure) and goes up to 29.92" Hg, which is perfect vacuum.

29.92-in.-Hg The maximum vacuum that can be achieved in locations above sea level will be less than 29.92-in. -Hg. The force will be limited by the ambient atmospheric pressure. Vacuum pumps have maximum vacuum ratings based on sea level conditions and must be re-rated for operation at higher elevations.

Natural rubber should not be used in applications with continuous temperature of above 85 °C. For some high-temperature applications, that simply isn't high enough. However, certain synthetic grades of rubber have been chemically engineered to deliver superlative heat resistance in excess of 300 °C.

Rubber, like most other materials, has a temperature range in which it works the best. These temperatures vary by the type of rubber material used in the seal. Some have working ranges as low as -40 degrees and others can go as high as 150 degrees.

Strong suction: 600W High-powered Motor support strong suction of 15KPA, to pick up debris and deeply embedded dirt, such as cat litter, dog food crumbs, pet hair, and so on your marble and hardwood floor.

What is a Good Suction Power for a Vacuum Cleaner? An upright cordless vacuum cleaner should have at least 100 air watts to effectively clean a variety of floor surfaces, with the best Samsung vacuum cleaner reaching up to 280W¹.

The wattage of cyclone-type vacuum cleaners is mostly between 300-400W, while smaller stick-type vacuum cleaners typically have a wattage of 50-100W. It is said that a suction power of around 300W is needed to effectively vacuum small dust and debris, so keep this in mind as a reference.

This seems counterintuitive because most materials expand when they are heated and contract when they get cold. This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract.

Your results might have surprised you - the rubber band actually expands when it gets colder! This seems counterintuitive, since most materials expand when they heat up, and contract when they get cold. This occurs because of the unique polymer structure of rubber.
