SAE Threads
Similar to JIC except 45° conical sealing surfaces
SCFM
Standard Cubic Feet per Minute. Typically refers to the amount of compressed air a compressor
can produce.
Safety Factor
A ratio used to establish the working pressure of a hose based upon the burst pressure.
Typical Safety Factors are as follows:
1. Water hose up to 150 psi WP: 3 to 1
2. Hose for all other liquids, solid materials suspended in liquids or air and water hose over
150 psi WP: 4 to 1
3. Hose for compressed air and other gases: 4 to 1
4. Hose for liquid media that immediately changes into gas under standard atmospheric
conditions: 5 to 1
5. Steam hose: 10 to 1
Serration
The part of the shank (stem) that grips the hose tube.
Shank
The section of the fitting or coupling that is inserted into the hose.
Sintered
Process in which powdered metal is formed in a mold under extreme pressure to form a finished
part.
Styrene Butaline Rubber
Also known as SBR
Surge
A rapid rise and decrease of internal pressure.
Torque
Amount of force required to turn an object. Usually measured in inch pounds (in. lbs.) or foot
pounds (ft. lbs.)
Tube
The innermost part of the hose that’s purpose is to contain the media being transported.
Usually, rubber compounds or plastics are blended to give the tube specific properties so that
it is compatible with certain media.
UHMW
Ultra High Molecular Weight. Next generation of chemical hoses after cross-linked
polyethylene having a thin tube liner made from extremely dense material giving it excellent
chemical resistance properties.
Victaulic Groove
A style of couplings that has a groove cut near the end of the stem where threads would
typically be. The couplings are attached using a "C" shaped clamp that fits into the grooves on the
stem.
WOG
Water, Oil, Gas. Pressure rating for valves handling these products. This does not include
steam.
WP
Working Pressure
Working Pressure
The maximum pressure to which a hose assembly will be subjected to including pressure
surges.
XLPE
Cross-Linked Polyethylene tube material that has good chemical resistance properties.
