Stainless Steel Gangway Bushing Ø25 mm – Flush Mount AISI 316 Base

This stainless steel gangway base (bushing) is a high-strength mounting component designed for the most demanding applications. Fabricated from polished AISI 316 stainless steel, it offers superior corrosion resistance in marine environments and excellent mechanical durability. The bushing’s dimensions are standard: the visible round flange is about 80 mm in diameter, and the internal bore is 25 mm to accept the gangway’s pivot pin. These specifications match those of typical plastic bushings, making replacement or upgrade straightforward – the stainless bushing will fit into the same deck hole and footprint as the old one, using a similar installation pattern.

Advantages of the stainless bushing: The primary benefit is its exceptional resistance to wear and deformation. With frequent use of the gangway (for instance, on a charter yacht or any vessel with lots of boarding activity), plastic bushings can gradually loosen or abrade. Stainless steel, by contrast, maintains its shape and does not wear down from the friction of a stainless steel pin. This translates to a much longer service life and retention of a tight, wobble-free gangway connection. Moreover, AISI 316 steel will not corrode – even after years of saltwater exposure, it remains strong and shiny (though it’s always wise to occasionally rinse it with fresh water to remove salt buildup).

The flush-deck installation ensures that when you remove the gangway, only a sleek polished disc remains on the surface, which neither detracts from the deck’s appearance nor poses a tripping hazard. Often, stainless sockets like this come with a cover or plug (in some sets) to seal the hole when the gangway is not in place – further contributing to aesthetics and safety (no open holes for debris or feet to catch in).

Installing the stainless bushing involves fastening it with screws or bolts (all stainless) through holes in the flange – typically four, arranged symmetrically. Because the material is very strong, you can tighten it down firmly onto the deck, eliminating any potential play. It’s recommended to apply a suitable marine sealant under the flange to prevent water ingress into the deck core. Once installed, maintenance is minimal – mostly just occasional cleaning to keep it free of salt and grit.

The 42.659.25 stainless bushing is the ideal upgrade for those who demand maximum reliability from their boarding system. It is commonly found on large yachts and superyachts, where heavy passerelles require a metal foundation for security. It is also compatible with all Osculati gangways using a 25 mm pin, as well as most other brands with similar standards. Investing in this bushing means you’ll have a rock-solid mounting point for your gangway for years to come, with minimal upkeep and no worries about the socket cracking or needing frequent replacement.
