White threaded thru-hull flange with a 72 mm (2.83 in) threaded body for secure thru‑hull mounting and a neat deck/hull finish. Durable, UV‑stabilized construction and a flush flange reduce snagging and water intrusion when paired with the correct gasket and fittings.

• Material: UV‑stabilized marine‑grade nylon (PA66) - corrosion resistant, good resistance to saltwater, oils and common fuels; typical continuous service range −20°C to +80°C.
• Body length: 72 mm (2.83 in) - this is the threaded mounting depth (not the thread diameter).
• Thread options and size: offered in common marine thread standards (BSP or NPT/NPSM). Thread diameter/standard varies by variant-select the correct thread standard (BSP or NPT/NPSM) and nominal size for your existing fittings.
• Flange and cutout: flange outer diameter (OD), recommended cutout/through‑hole diameter and internal bore (ID) vary by thread size and manufacturer; consult the product dimensions on the variant or drawing before installation.
• Max hull/deck thickness: accommodates up to the 72 mm threaded depth; use with the supplied/backing nut for thinner decks as required.
• Included: gasket and locking/backing nut are typically supplied with this flange-see the product variant details for exact inclusions.
• Application: replacement or new thru‑hull installations for plumbing, vents or wiring passthroughs; confirm compatibility with mating fittings and sealant requirements.
• Notes: measure existing fittings and confirm thread standard, thread diameter, flange OD and cutout diameter before purchase; select the product variant that matches your thread standard and size.
