Continental ContiTech Whitewater Black Rubber Pressure Washer Hose Assembly, Male NPT Couplings

This branded hose is manufactured for use on either steam cleaner machines or combination steam cleaner/pressure washer machines. Its tube is constructed of Pyrosyn, a special form of EPDM (ethylene propylene diene monomer) synthetic rubber for high heat resistance. Its cover is made Hysunite hypalon synthetic rubber, which is resistant to chemicals and has an RMA Class B (medium oil resistance) rating, which means that it will undergo a maximum volume change of +65% and will retain a minimum of 50% of its tensile strength after exposure to oil. It is reinforced with braided steel wire, which provides the strength necessary to reach and maintain the maximum pressure ratings appropriate for its service. If employed for steam cleaning, this hose will function effectively with water temperatures up to 325 degrees F (163 degrees C) at a maximum pressure of 350 psi. For pressure washer service, this hose is rated for water temperatures up to 250 degrees F (121 degrees C) at a maximum pressure of 2500 or 3000 psi. This hose comes fitted with two male NPT swivel couplings.

Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method:

S = Size (ID, OD, and length)

T = Temperature (maximum and minimum temperatures of material being transported)

A = Application (industry or process)

M = Material (to be conveyed, type and concentration)

P = Pressure (maximum working pressure)

E = Ends (type of end connectors or couplings on hose)

D = Delivery method (volume and velocity)

The inside diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose due to heat generation or excessive turbulence. The hose must be capable of withstanding the minimum and maximum temperatures that occur within the hose system. Some applications require specialized oils or chemicals to be conveyed through the system. In this case, hose selection must ensure compatibility of the hose tube, cover, couplings and O-rings with the fluid used. Industrial hoses are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.
