Nairn 6 inch Inspection Port White
Choose an Australian-made Nairn 6 inch inspection port with a white finish for a clearly specified marine access fitting. Its ABS plastic rim and coloured lid are paired with a wide caulking flange, helping you plan the surrounding mounting and sealing area.
The EPDM rubber O-ring is located in the rim. This seal material is selected for weather resistance and forms part of the port’s watertight closing arrangement. Inspect the seal and mating surfaces when servicing an existing port so the replacement is fitted to a suitable assembly.
This version uses a 150mm hole and measures 195mm across the outside. The 195mm outside diameter is worth checking carefully when replacing a different six-inch port, as nominal size alone does not establish the same flange footprint.
Select code 404621 for this white standard Nairn variant. Match the size, finish and mounting arrangement together when replacing an older fitting; a port from another range should not be assumed interchangeable because it shares the same nominal diameter.
Choosing and using this product
Check the stated supply quantity and inclusions when ordering. Some listings describe an individual component, while others supply a pair, pack or complete assembly. Match any additional fixings and supporting parts to the installation requirements rather than assuming they accompany the visible fitting.
Consider how the fitting will be used in the normal boat layout. Allow room for hands, tools and any intended movement, and check that it does not obstruct an access opening or another control. Offer the parts into position before marking or making permanent changes.
Check the mounting area as well as the visible size of the fitting. Space behind the panel, access for fixings and clearance around neighbouring hardware all affect a practical installation. For a replacement, compare the existing hole pattern before assuming the new item will cover it.
