Product Description

The Coilhose Pneumatics PU14-50B-B Flexcoil coiled polyurethane air hose has a 1/4" inside diameter (ID) and is 20 ft. long. This hose is a single-component tube made of blue polyurethane, which provides resistance to kinking, weathering, and abrasion; sensitive treatment of delicate surfaces; and resistance to chemicals, oil, and other petroleum-based fluids. The tails of this hose are straight, offering the protection to fittings and hose ends that are a feature of standard air whip hoses. This hose provides both durability and flexibility at temperatures ranging from -40 to +165 degrees F, and it has a persistent coil memory. It has a maximum pressure rating of 125 psi, and comes equipped with two 1/4" factory-installed, brass reusable strain relief Male Pipe Thread (MPT) swivel fittings. This hose is manufactured as a lighter-weight alternative to bulkier rubber and plastic hoses for use in a wide range of industrial applications, such as manufacturing, auto repair, robotics, and others.

Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method to help determine the type of hose needed:

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.

Coilhose Pneumatics manufactures straight and coiled hoses, couplers, connectors, fittings, filters, regulators, and lubricators for pneumatic tools and applications. The company, founded in 1969, is headquartered in East Brunswick, NY.
