Hydraulic Hose Fittings
|Publication Date:||1 March 2019|
This SAE Standard provides general and dimensional specifications for the most common hose fittings used in conjunction with hydraulic hoses specified in SAE J517 and utilized in hydraulic systems on mobile and stationary equipment.
The general specifications contained in Sections 1 through 17 are applicable to all hydraulic hose fittings and supplement the detailed specifications for the 100R-series fittings contained in the later sections of this document.
This document shall be utilized as a procurement document only to the extent agreed upon by the manufacturer and user.
Refer to SAE J517 for specifications of hose and information on hose assemblies. SAE J1273 contains information on application factors affecting hose fittings, hose, and hose assemblies.
The rated working pressure of a hose assembly comprising SAE J516 fittings and SAE J517 hoses shall not exceed the lower of the two working pressure rated values.
The following are hose fitting types contained in this document:
Section 18 O-ring face seal hose fittings shall be as shown in Figures 4 to 7 and in Tables 2 to 5.
Section 19 Flareless 24-degree cone hose fittings shall be as shown in Figures 9 to 10 and in Tables 7 to 8.
Section 20 Four-bolt split flange hose fittings shall be as shown in Figures 11 to 17 and in Tables 9 to 15.
Section 21 Straight thread O-ring hose fittings shall be as shown in Figure 18 and in Table 16.
Section 22 37-degree flare hose fittings shall be as shown in Figures 19 to 22 and in Tables 17 to 20.
Section 23 Dryseal pipe thread hose fittings shall be as shown in Figure 23 and in Table 21.
Male and female 45-degree flare hose fittings shall be as shown by the 37-degree flare figures and tables.
It is recommended that where step sizes or additional types of fittings are required, they be designed to conform with the specifications of this document insofar as they may apply. The following general specifications shall supplement the dimensional data contained in the tables with respect to all unspecified detail.
