GUIDI 1260 series bronze skin fitting is a threaded through-hull connection for marine water, seawater, and piping systems. It is mounted through the hull and connects the external water contact with the internal piping system for, for example, an engine, generator, watermaker, toilet, water intake, or drain. The product is a skin fitting without an integrated valve or hose barb.
The fitting is made of solid bronze with a rounded external head, a wide flange, and a flanged lock nut for fastening on the inside of the hull. The parallel, cylindrical G/BSPP thread follows ISO 228/1 and BS 2779 and must be connected to compatible valves, fittings, or pipe parts. BSPP must not be confused or combined with tapered BSPT or NPT. Sealing must be performed with a suitable gasket, O-ring, sealing washer, or thread sealant depending on the installation design.
The series is available with nominal pipe threads from 3/8" to 3". The variant-specific dimensions range from 64 to 158 mm in total length, 60 to 150 mm below the flange, 28 to 122 mm in flange diameter, and 11 to 76 mm in clear internal passage. The solid bronze construction is suitable for maritime installations where resistance to seawater is important. The use of compatible bronze components throughout the system is recommended to limit the risk of galvanic corrosion.
The fitting can be combined with matching, separately sold Manta or Goccia bronze water intakes as well as relevant lock nuts. These components are not included. Regular inspection and cleaning are recommended to remove fouling, plastic debris, and other blockages. Bonding or galvanic protection can be applied where the installation design allows it.
Series 1260 is patented and covered by RINA type approvals according to ISO 9093:2020, including DIP235223CS/002, as well as Lloyd’s Register approval LR2556185TA-01. The series also complies with UNI EN ISO 9093-1 where applicable. Installation in recreational craft with a hull length of up to 24 meters must be performed according to the manufacturer's instructions and ISO 9093:2020. The Lloyd’s approval does not include fire extinguishing or flammable media.
