4 ISO 2015 All rights reserve Forewor ISO (the Interntionl Orgniztion for Stnriztion) is worlwie feertion of ntionl stnrs oies (ISO memer oies). The work of prepring Interntionl Stnrs is normlly crrie out through ISO technicl committees. Ech memer oy intereste in suject for which technicl committee hs een estlishe hs the right to e represente on tht committee. Interntionl orgniztions, governmentl n non-governmentl, in liison with ISO, lso tke prt in the work. ISO collortes closely with the Interntionl Electrotechnicl Commission (IEC) on ll mtters of electrotechnicl stnriztion. Interntionl Stnrs re rfte in ccornce with the rules given in the ISO/IEC Directives, Prt 3. Drft Interntionl Stnrs opte y the technicl committees re circulte to the memer oies for voting. Puliction s n Interntionl Stnr requires pprovl y t lest 75 % of the memer oies csting vote. Attention is rwn to the possiility tht some of the elements of this prt of ISO 8434 my e the suject of ptent rights. ISO shll not e hel responsile for ientifying ny or ll such ptent rights. Interntionl Stnr ISO ws prepre y Technicl Committee ISO/TC 131, Flui power systems, Sucommittee SC 4, Connectors n similr proucts n components. This secon eition cncels n replces the first eition (ISO :1994), which hs een techniclly revise. ISO 8434 consists of the following prts, uner the generl title Metllic tue connections for flui power n generl use: Prt 1: 24 compression connectors Prt 2: 37 flre connectors Prt 3: O-ring fce sel connectors Prt 5: Test methos for three hyrulic flui power connections (revisions will e pulishe s ISO 19879) Prt 6: 60 cone connectors n wel on nipples with or without O-ring seling NOTE: ISO will chnge its numer to ISO when the revision is pulishe. This prt of ISO 8434 is se on the USA stnr ANSI/SAE J514. The thres for the 37 flre connection re unifie inch thres to ISO 263. The inch thres were not chnge to metric thres to ISO 261 to llow connectors complying with this stnr to e use in existing pplictions without requiring chnge to tue or hose ssemlies. Also, the thre-to-nut overtorque n sel performnce hve een extensively teste; to chnge to metric thres woul require n extensive test progrm t consierle cost without proviing ny functionl improvement. The thres re integrl to themselves, connectors of this type mtch only to themselves, n other thn hving metric thres, no vlue in chnging coul e foun. Mjor interntionl compnies tht hve use these connectors hve opte the esign without noting ny prolems.

These connectors re for use in flui power n generl pplictions within the limits of pressure n temperture specifie in this prt of ISO They re intene for the connection of tues n hose fittings to ports in ccornce with ISO , ISO , ISO n ISO (See ISO for relte hose fitting specifiction.) These connectors provie lekproof, full-flow connections in hyrulic systems operting to the working pressures shown in tle 1. Becuse mny fctors influence the pressure t which system performs stisfctorily, these vlues shll not e unerstoo s gurntee minimums. For every ppliction, it is recommene tht sufficient testing e conucte n reviewe y oth the user n mnufcturer to ensure tht require performnce levels re met. NOTE 1 For new esigns in hyrulic flui power pplictions, see the requirements given in 9.6. NOTE 2 For use uner conitions outsie the pressure n/or temperture limits specifie, see 5.5. Both metric n inch tuing cn e ccommote y chnging the sleeve (see Figure 9). In the pst, these connectors hve een use preominntly with inch tuing. For new n future esigns, the use of metric tuing is preferre. This prt of ISO 8434 lso specifies performnce n qulifiction test for 37 flre connectors.
