This Sam Allen bung with snap handle in 35mm size slots straight into a 35mm drain socket so you can keep water out of the hull while you get out there. The snap handle throws roughly 40–50mm to expand the bung and hold against the drain wall. The kit suits standard above drain sockets where a 35mm bore is already fitted through the transom.

The handle and top plate use tough nylon about 8–10mm thick, giving you solid grip without corroding in salt water. The bung body is sized to match the 35mm socket for a snug mechanical seal. The compact overall height around 45–55mm keeps it low profile so it will not crowd the cockpit. It is simple gear, built tough enough for regular use on Aussie runabouts and tinnies.

Q: Does this bung fit any 35mm drain socket?

It fits drain sockets with a 35mm internal diameter. As long as the socket bore is 35mm, the expanding body can grip the wall properly. If the bore is smaller, the bung will not insert. If it is larger, the bung may not expand enough to seal, so measuring the socket before buying is important.

Q: Can I use this bung as a spare on board?

Yes, it works well as a spare bung for 35mm drain fittings. Many skippers keep an extra bung in a side pocket or hatch. A spare helps if the main bung is lost at the ramp. Carrying a known 35mm size keeps changeovers simple when you are loading up in a hurry.

Q: What material is the handle made from?

The handle is made from nylon. Nylon stands up to regular contact with water and standard marine cleaners. It will not rust like mild steel in a wet bilge. The material also keeps weight down, which suits small open boats and tinnies that already carry a lot of gear.

Q: Is any safety cord attachment included on this part number?

This specific part number 23134 does not list a safety cord tie-off feature. Other part numbers in the same family include a tie-off point, but this one focuses on a simple expanding bung. If you want to secure it, you can mount the bung somewhere reachable. Keeping it in a set spot on the boat helps avoid misplacing it.
