This part of ISO 8434 specifies general and dimensional requirements for the design and performance of 24° cone connectors with O-ring weld-on nipple that are suitable for use with steel and stainless steel tubes with outside diameters from 6 mm to 42 mm, inclusive. These fittings are for use in fluid power and general applications where elastomeric seals can be used, within the limits of pressure and temperature specified in this part of ISO 8434. S series fittings in accordance with this part of ISO 8434 may be used at working pressures up to 63 MPa (630 bar¹). L- series fittings in accordance with this part of ISO 8434 may be used at working pressures up to 25 MPa (250 bar) (see table 1).
They are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149-1, ISO 1179-1 and ISO 9974-1.
NOTES
1 For new designs in hydraulic fluid power applications, see the requirements given in 9.6.
2 For use under conditions outside the pressure and/or
temperature limits specified, see 5.4.
