* For Anti-Static Grade, add 10 to the 3-digit part number e.g. 70-100 becomes 70-110. For High Pressure Gas Grade, add 20, eg 70-200- becomes 70-220.

Note: A few of the sizes of hose and fittings listed above are available as ex-stock items and are priced accordingly. However, most of the items are not stocked, and will therefore incur a minimum order charge or a set-up charge for small quantities.

Temperature & Pressure

  • Temperature affects the Maximum Working Pressure (MWP) as listed above, so for temperatures above 130˚C reduce the MWP by 0.75% for each 1˚C above 130˚C. Example: at 180˚C, reduce the MWP by (180 - 130) x 0.75 = 37.5%.
  • Pressure Ratings above 100 Bar (1500 psi) only apply for the transfer of non-penetrating fluids. If gases or penetrating fluids are used in the application, or used during pressure testing at pressures above 100 Bar, HPG grade hose is required.
  • Maximum Working Pressures (MWP) listed are calculated on the basis of a 3:1 safety factor relative to the burst pressure, so Burst Pressure = 3 x MWP. If MWP is required based on a 4:1 safety factor (e.g EN 16643 requirement), multiply the listed value by 0.75.
