PSS Shaft Seal Hose Barb Plug

The PSS Shaft Seal Hose Barb Plug is a critical maintenance component for any serious boater running a through-hull shaft seal system. After years on the water, you learn that a properly maintained shaft seal is the difference between a trouble-free season and an unexpected haul-out. This plug serves as a protective barrier and diagnostic access point for PSS shaft seal installations, allowing you to monitor seal condition and maintain system integrity without constant bilge checking.

Designed specifically for the PSS shaft seal system, the hose barb plug connects directly to the cooling/lubrication line and provides a secure, leak-free interface. The barb design ensures a tight grip on hose material without requiring hose clamps in all installations, though marine-grade hose clamps are always recommended for added security in rough conditions. This plug is engineered to withstand the pressures and salt-water exposure that come with extended offshore use, maintaining its seal integrity regardless of whether you're running freshwater lakes or ocean passages.

If you own a vessel with a PSS shaft seal system—whether it's a cruising sailboat, trawler, or offshore sportfisher—keeping replacement plugs on hand is sound seamanship. The lightweight component weighs just 1 pound and takes up minimal locker space, making it an ideal spare for extended offshore passages where hardware failures can strand you far from port. Installation is straightforward: simply disconnect the cooling line, remove any existing plug, and barb the new plug firmly onto the hose, then reconnect. This is standard maintenance that any conscientious skipper should handle annually before the season begins.
