This part of ISO 9093 specifies requirements for metallic through-hull fittings, seacocks and hose fittings that specifically form part of water intake and discharge lines, and for wet exhaust outlets used insmall craft of up to 24 m length of hull. Through-hullfittings for other purposes are not covered.
This part of ISO 9093 applies to seacocks and through-hull fittings with cylindrical pipe threads in accordance with ISO 228-1, and with joints for conical pipe threads in accordance with ISO 7-1, with nominal diameters of 1/4 in, 3/8 in, 1/2 in, 3/4 in, 1 in, 1 1/4 in, 1 1/2 in, 2 in, 2 1/2 in, 3 in or 4 in.
NOTE 1 The reasons for developing this part of ISO 9093 are that detail dimensions of components of water intake and discharge lines, and wet exhaust outlets passing through a craft hull differ considerably, thus limiting the interchangeability of these parts.
