Glossary of terms | Central States Hose
the use of liquid pressure to test a hose or hose assembly for leakage, twisting, and or hose change in length.
the abbreviation for inside diameter.
an application of force in a manner to produce sudden strain or motion, such as hydraulic pressure applied in a hose.
a temporary or permanent distortion of the hose induced by bending beyond the minimum bend radius.
the line of printed information that runs parallel on the side of a manufactured hose giving details such as part number, PSI rating, hose size and manufacturing data.
a form, usually of elongated round section, used for size and support hose during fabrication and or vulcanization. It may be rigid or flexible.
to which a hose may be bent without compromising the integrity of construction
Mine Safety and Health Administration.
NBR Buna-N. A family of acrylo-nitrile elastomers used to make industrial hose.
National Stock Number
The total length of a hose assembly, which consists of the free hose length plus the length of the couplings.
the process of migration of a substance into and through another, usually the movement of a gas into and through a hose material; the rate of permeation is specific to the substance, temperature, pressure and the material being permeated.
pounds of pressure per square inch of area (lb2/in).
polytetrafluoroethylene, a high molecular weight fluoroplastic polymer with carbon atoms shielded by fluorine atoms having very strong inter atomic bonds, giving it chemical inertness.
polyvinyl chloride. A low cost thermoplastic.
Society of Automotive Engineers
That part of the coupling which fits into the I.D. of the hose.
a document setting forth pertinent details of a product.
a method of applying reinforcement in which there is not interlacing between individual strands of the reinforcement.
wire incorporated in a hose to conduct static electricity.
a rapid and transient rise in pressure.
the innermost continuous all-rubber or plastic element of a hose.
a non-reinforced, homogeneous conduit, generally of circular cross-section.
the measure of a hoses ability to resist negative gauge pressure.
a process during which a rubber compound, through a change in its chemical structure, improves or extends elastic properties over a greater range of temperature.
A hose containing wires to give added strength, increased dimensional stability and crush resistance.
maximum pressure at which a hose is designed to operate.
