Engine Block Drain Petcock BBC SBC BBF BBO Marine WinterizeThese 1/4 npt brass drain valves are a must if you own a inboard marine engine of any kind. This is also a common replacement item for mercrusier, volvo, omc, berkeley, indmar, hardin, harman, guardian, and crusader engines.
Add one of these to each side of your engine block to ensure 100% winterization. In some cases marine exhaust manifolds can have npt threads to add a drain as well.
This petcock drain doubles as a small drain when twisted slightly open, or the insert can be removed for full block discharge.
This listing is for a pair (2) brass 1/4 npt drain valves. Some engines may need a reducer added to accommodate 1/4 thread size.
