The Amflo 37L-30BD red rubber lead-in air hose has a 3/8" ID and is 30" long. It is designed to absorb the frequent pulsations and vibrations of air compressors and pulsating pneumatic tools, prolonging the life of the hose and its fittings. Its rubber tube and cover provide flexibility in cold temperatures and resistance to abrasion, and its polyester yarn reinforcement provides the strength necessary to reach and maintain its maximum pressure rating of 300 pounds per square inch (psi). This hose is capable of functioning effectively at temperatures ranging from -20 to +165 degrees F, and it comes equipped with one 1/4" factory-installed brass female National Pipe Thread Taper (NPT) fitting and one 1/4" factory-installed brass ball-swivel male NPT fitting for protection against damage caused by movement at the tool end. This hose is suitable for a wide range of commercial and industrial pneumatic applications where frequent pulsation and vibration occurs, such as with air compressors, impact tools, and nail guns, among others.Industrial hoses transfer or convey air or liquid in hose systems. When selecting industrial hoses, use the STAMPED method: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.Plews & Edelmann manufactures automotive and pneumatic hose, lines, reels, accessories, fittings, and lubricants under the Edelmann, Amflo, Omega, LubriMatic, and UltraLube brands.
