*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 to the 3-digit part number (e.g. 70-100- becomes 70-120-)

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 set-up charge for small quantities.

Temperature & Pressure

Temperature affects the Maximum Working Pressure (MWP) as listed above, so for temperatures above 130C reduce the MWP by 0.75% for each 1C above 130C. Example: at 180C, 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 at higher pressures, 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, multiply the listed value by 0.75.
