About this part

Product Details

This is a Peterson Fluid Systems water neck spacer, part number 10-2257. It's machined from billet aluminum and is designed to fit a 1 1/4 inch water neck opening. This spacer is useful for custom cooling system setups, especially when you need to route cylinder head water lines using AN fittings. It's built to accommodate a thermostat, so you can maintain proper engine temperature control.

The flanges on this spacer are o-ringed, which helps create a solid seal against the water neck and cylinder head. You can choose different port sizes for your water lines, and this particular model features -10 AN ports, which are common for higher-flow applications in custom builds. It's a well-built component for anyone fabricating or modifying their engine's cooling system.
