1/8" Brass Drain Spigot (std size for Pontiac blocks) FSC-135

Replaces the block drain plug with a small T-handle spigot, so draining the block is a matter of turning it open by hand and catching the coolant instead of getting a wrench onto a fitting low on the block with the headers in the way.

Brass, 1/8" NPT, the standard drain size for Pontiac blocks. Brass will not seize into the block the way a rusted steel plug does, which matters at a location that sits at the lowest point of the water jacket where the rust and casting sand collect.

There is one drain port on each side of the block, so order two. Use sealant on the pipe threads and do not overtighten into cast iron.
