Product Details

The Sierra 18-4218 is a brass drain cock designed for marine engine cooling systems. This petcock-style drain valve features 1/4 inch NPT threading for direct installation into OEM engine manifolds and block drain ports.

Key Features:

  • Premium brass construction for corrosion resistance in marine environments
  • 1/4 inch NPT male threads for standard engine block fitment
  • Gold-colored brass finish
  • Petcock design allows easy winterization and cooling system drainage
  • Direct replacement for OEM drain taps on inboard and sterndrive engines

This drain cock is an essential component for seasonal maintenance, allowing quick and complete drainage of engine coolant for winterization or cooling system service. The brass construction ensures long-term durability in harsh marine conditions.

My husband found the part we needed for an older model vehicle and it was reasonably priced. The item was shipped in a very timely manner and we will definitely consider ordering from here again.

Fast and easy

The best prices on the net.

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

1st time shopper order shipped quickly very satisfied

Good price. So far so good

quick, easy

Had a great price on the parts that I wanted, informed me immediately that the products were back ordered from the manufacturer, and wanted to know if I wanted the parts dropped shipped from the manufacturer or what. They said if I wanted to wait it would take around 2 weeks to ship, they arrived in a week.

Ordered a exhaust and a pressure sensor for my 6.0 diesel. Excellent customer service. Fast shipping, cheapest price on the internet. I will buy from autoplicity again. Thanks!<br><br>Joe
