If you want a straightforward bung for the boat, the Sam Allen Rubber Bung Size 10 keeps it simple and reliable for bung holes between 10mm and 20mm. The tapered rubber body bites into the drain fitting so water stays where it should when you are loading or launching. One bung covers a typical small hull drain, so you can carry a spare in the tackle box and get out there without fuss.

This size 10 bung is black rubber with a minimum diameter of 20.5mm at the tip and a maximum diameter of 25mm at the base. That taper gives enough compression to tackle standard marine drain housings without extra hardware. The one‑piece rubber construction handles regular contact with water around Australian ramps and estuaries. It is smart buy gear for anyone who wants simple drain control that just works on the boat.

Q: What bung hole size does this Rubber Bung Size 10 actually suit?

This bung suits bung hole sizes from 10mm to 20mm in diameter. This range covers many small boat drain fittings and transom bungs on tinnies and runabouts. The bung itself tapers from 20.5mm up to 25mm to create compression against the housing. Always measure the internal diameter of the bung hole to confirm it sits within the 10mm to 20mm range before use.

Q: How many bungs are included when I order this size 10 bung?

This listing supplies one rubber bung. The unit quantity is listed as 1, so each add-to-cart equals a single plug. If you want a spare for the tackle box or have multiple drains, order extra units. Many boaties keep at least one spare bung on hand in case one is misplaced at the ramp.

Q: What colour is the Sam Allen Rubber Bung Size 10?

This bung is supplied in black. The black finish matches most transom and deck hardware and keeps marks less visible in marine use. The colour also makes the bung easy to spot in the toolbox or side pocket. It is a practical choice for everyday boat setups.

Q: Does this bung use any metal parts or hardware?

No, this bung is a single piece of rubber. The design avoids metal components that can corrode in salty environments. A solid rubber body keeps the seal simple and reduces parts that might fail. This style works well where you just need a push-in plug for basic drain control on the boat.

• Suitable for plugging marine bung holes from 10mm to 20mm in diameter.
• Commonly used in boat drain and bung fittings where a tapered rubber plug is required.
• Check that the bung hole diameter falls within the 20.5mm to 25mm bung diameter range for proper compression fit.
