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.
If you need assistance identifying the correct thread standard or measuring an existing fitting, contact our support with photos and measurements and we will help confirm the correct variant.
