Class Vocabulary

Term	Definition
active component	A component characterized by being a source of activity in a fluid system. Active fluid components such as pumps perform an action on hydraulic and pneumatic fluids.
AISI	The American Iron and Steel Institute. AISI is an association responsible for setting standards and creating numbering systems for various ferrous metals.
ASTM	The American Society of Testing and Materials. The ASTM writes and updates specifications for a broad range of materials, including fluid conductors.
brazed	Joined using a filler metal melted at a temperature above 1540°F (840°C), but below the melting point of the base components.
burst pressure	The pressure rating that indicates the pressure at which a conductor failed during a pressure rating test.
cartridge valve	A fluid valve that is screwed directly onto a manifold port.
conductor	A component such as pipe, tube, or hose that conveys liquids within a hydraulic system.
contaminant	Any foreign substance that may cause a loss of efficiency or a breakdown in a fluid system.
cover	The outermost layer of hose that protects the inner layers from the environment and wear.
crest	The high point or peak of a thread.
drilled metal block manifold	A manifold made of steel, aluminum, or cast iron that is drilled to make fluid passages.
dryseal	A sealing condition caused by the crest of one thread contacting the root of another thread. Dryseals do not allow fluid to leak from a fluid system.
external leakage	The unintentional movement of fluid from a system into the environment.
fatigue life	The length of time a conductor remains in service. Conductors with a low fatigue life do not last long under normal working conditions.
fitting	A fluid component that connects, redirects, extends, or terminates the run of a fluid conductor.
flank	The side of a thread between the root and crest.
flow rating	An indication of the volume of fluid that a conductor can handle in a given time.
force multiplication	The exponential increase in available power usually associated with tools and power transmission systems.
hoop strength	The resistance of a fluid conductor to inside pressure. Hoop strength indicates the ability of a conductor to maintain its structural integrity.
hose	A type of hydraulic fluid conductor that joins other components usually in a non-linear fashion. Hose bends and flexes and is the most versatile hydraulic conductor.
inner tube	The innermost layer of hose which contacts the fluid.
inside diameter	The interior surface of a cylindrical part or hole.
internal leakage	The unintentional movement of fluid from one component to another.
laminar manifold	A manifold that is comprised of several layers of metal that are brazed together.
leakage	The unintended movement of fluid either out of a fluid system or from one fluid component to another. Leakage causes a loss of effiency and often leads to system failure.
manifold	A block of metal with multiple integrated channels designed to conduct fluid in confined spaces.
minimum bend radius	A value indicating the limit beyond which a hose should not be bent. If a minimum bend radius is exceeded, a hose will not perfom properly.
modular-block manifold	A fluid conductor that usually supports one valve and is designed to be used in conjunction with other manifolds and fluid components.
nominal size	The size by which pipe is known and sold in the fluid component market. The nominal size of pipe differs from the actual size of pipe.
nonpositive seal	A seal that allows a small amount of fluid to pass through.
outside diameter	The exterior surface of a cylindrical or round feature.
passive component	A component characterized by inactivity. Passive fluid components such as conductors do not perform an explicit action on fluids, but allow fluids to act upon them.
pipe	A type of hydraulic fluid conductor that joins other components, usually in a straight line and on a permanent basis.
plug	A pipe fitting that terminates a run by closing an end. A plug has male threads.
positive seal	A seal that does not allow any amount of fluid to pass through.
pressure rating	An indication of the amount of pressure a fluid conductor can withstand.
radius die	A bending mechansim used to bend a tube to a particular radius specification.
reinforcement	A layer of woven material used to strengthen a hose. Hose may have several layers of reinforcement.
root	The bottom of a thread valley.
SAE	The Society of Automotive Engineers. SAE writes specifications and other data used in a broad range of industries.
safety factor	The ratio of burst strength to working strength. A conductor with a safety factor of 5:1 has a burst pressure that is 5 times the working pressure.
schedule number	A number that describes the thickness of a pipe wall.
single-piece manifold	A fluid conductor that contains the fluid passages and valves of a complete system.
socket weld flange	A device that is welded to the end of pipe so that the pipe can be bolted to another pipe with a similar flange. Socket weld flanges enable a pipe to be disconnected and reconnected with ease.
spiral clearance	The presence of space between the root of one thread and the crest of another along the entire length of the thread. Spiral clearance allows fluid to leak from a fluid system.
support	A mechanical device that fixes and stabilizes the position of a fluid conductor.
tapered	Gradually decreasing in size from one end of the object to the other.
tensile strength	The ability of a metal to resist forces that attempt to pull apart or stretch it.
threads	A raised, helical ridge around the interior or exterior of a cylindrically shaped object. Threads are found on conductors and fittings and are used to join components of a fluid system.
threads per inch	TPI. The number of threads in a linear inch along the length of a workpiece.
tubing	A type of hydraulic fluid conductor that joins other components usually in a non-linear fashion. Despite being stronger than pipe, tubing is easily bent.
wall thickness	A value that indicates the thickness of the tubing wall. Wall thickness may remain unchanged as the outside diameter and inner diameter change.
working pressure	The pressure rating that indicates the maximum pressure a conductor should experience in service.
