Quick Summary
This is a 2 pack of 1/2 in. NPT solid brass drain plugs for boat hull transom drain holes. The main buying check is fit, since the plug is meant for a standard transom drain hole and the stated thread size matters for compatibility.
The solid brass build and deep threads are presented as the key features of the plug. If you are replacing a drain plug, compare the thread size and the drain hole opening before choosing an offer.

What to Compare Before Buying
- Thread size: This plug is stated as 1/2 in. NPT. Compare that with the size needed for your drain opening.
- Drain hole fit: It is meant for a standard transom drain hole, so the opening should match the plug you plan to replace.
- Pack quantity: This is a 2 pack, which matters if you want one installed plug and one spare.
- Material: Solid brass is the stated material, so compare it with the material you want for the replacement.
Before You Decide
Confirm the 1/2 in. NPT size, the transom drain hole fit, and the 2 pack quantity before choosing an offer. If you are replacing existing hardware, match the thread size to the part already in use.
Understanding 1/2 in. NPT
The 1/2 in. NPT designation identifies a nominal pipe-thread size; it is not a measurement of the drain-hole diameter. When checking a replacement, confirm that the mating fitting uses the same NPT thread type and nominal size rather than relying on an opening measurement alone.
