Overview
This plastic drain plug is a compact, reliable solution for bilge and cockpit drainage on small craft. The moulded black base and bung are designed for repeat use, while the coarse four point thread copes well with sand and sediment. Part Number 192412 identifies this exact variant with a 25mm cut-out. Because installation is simple and maintenance is minimal, the plastic drain plug suits quick repairs as well as new builds.

Compatibility and Fitment
This unit suits 25mm cut-outs in transoms, cockpits and bilge wells. Because the base is 52x35mm, it usually covers existing holes from similar rectangular drain plugs. Pre-drill for the specified 5 c/s mount screws, then bed the base on a suitable marine sealant before tightening evenly. Therefore, the plastic drain plug installs cleanly without special tools.
Compliance and Safety
Always position the plug so it can be reached quickly from the cockpit or boarding platform. Check seating and thread engagement before every launch. After use in sandy locations, rinse the plug and seat to ensure the coarse thread remains clear. Consequently, you maintain a positive seal and reduce the risk of water ingress.
Marine Applications
Use this plastic drain plug in tinnies, runabouts, sailing dinghies and small RIBs where a light, corrosion free bung is preferred. It is ideal as a primary hull drain, yet it also works as an auxiliary cockpit or fish-well drain. Because the design is simple, spares can be carried and swapped in seconds.
