HOSE CONSTRUCTION 4.1 Coupled and Uncoupled Synthetic Rubber Tube and Cover (SAE 30R2) 4.1.1 Type 1 The construction of this hose em
41、bodies a smooth bore tube of suitable synthetic rubber material, reinforced with one ply of braided, knit, spiral, or woven fabric, and finished with a suitable oil- and ozone-resisting synthetic rubber cover. 4.1.2 Type 2 The construction of this hose embodies a smooth bore tube of suitable synthet
42、ic rubber material, reinforced with two braided plies or multiples of woven fabric, and finished with a suitable oil- and ozone-resisting synthetic rubber cover. 4.1.3 Type 3 The construction of this hose embodies a smooth bore tube of suitable synthetic rubber material, a single braided ply of text
43、ile reinforcement, and finished with a suitable oil- and ozone-resisting synthetic rubber cover. 4.2 Lightweight Braided Reinforced Lacquer, Cement, or Rubber Covered Hose (SAE 30R3) The construction of this hose embodies a smooth bore tube of suitable synthetic rubber material, reinforced with one
44、braided ply of cotton or other suitable material and finished with a gasoline-, oil-, and water-resistant flexible coating of lacquer, cement, or synthetic rubber. 4.3 Wire Inserted Synthetic Rubber Tube and Cover (SAE 30R5) A wire inserted hose for fuel and oil filler and vent use in mobile, statio
45、nary, or marine applications. The hose is furnished uncoupled in specific lengths and is secured in application by the use of suitable clamps. The hose is particularly useful in applications where it must be installed in a curved configuration and where resistance to collapse is desirable. The const
46、ruction of this hose embodies a fuel- and oil-resistant tube, a helical high-carbon steel wire embedded in the convoluted section of this hose and running out into the plain 1 ends and an ozone- and oil-resistant cover. A ply of fabric or cord may be applied between the tube or cover and the helical
47、 wire. A ply of fabric must be used to reinforce the ends. 4.4 Low-Pressure Coupled and Uncoupled Synthetic Rubber Tube and Cover (SAE 30R6), (SAE 30R7), (SAE 30R8) Hose which may be supplied either coupled or uncoupled for use with gasoline, diesel fuel, lubrication oil, or the vapor present in eit
48、her the fuel system or in the crankcase of internal combustion engines in mobile, stationary, and marine applications. Exposure of these hoses to gasoline or diesel fuel which contain high levels, greater than 5% by volume, of oxygenates, i.e., ethanol, methanol, or MTBE (methyl tertiary butyl ether
49、), may result in significantly higher permeation rates than those listed for 30R6, 7, or 8. This hose is for maximum working pressures of 0.34 MPa (50 psi) up to and including 9.53 mm (3/8 in) ID and 0.24 MPa (35 psi) for over 9.53 mm (3/8 in). For 30R6 hose in excess of 25.40 mm (1 in), the working press
