Nairn 6 inch Inspection Port O-Ring
Renew the rim seal in a matching Nairn 6-inch inspection port with this replacement EPDM rubber O-ring. It is a size-specific spare for maintaining the port’s existing sealing arrangement.
The 6-inch designation refers to the inspection-port family. Confirm the installed port is the corresponding Nairn model rather than using that nominal measurement as the O-ring’s physical diameter.
EPDM rubber provides weather resistance, and the seal fits in the port rim. Check the groove and lid contact surface when replacing the ring. This component supplies the replacement seal; it does not replace the lid or rim of the complete port.
Choosing and using this product
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.
Include the attachment points in routine boat inspections. Keep moving or seating surfaces clear where applicable, and follow the product’s care instructions for its material and finish. Retaining the size and part code is useful when replacing another fitting elsewhere on the boat.
The listed material, finish and dimensions help you select a version that suits the job and surrounding fittings. Measure the actual location rather than relying on a familiar-looking shape. Small differences in projection or spacing can change how comfortably the completed arrangement works.
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.
