The Peterson Fluid Systems O-Ring Kit for the 700 Series Filter is a dedicated sealing package for marine cooling system maintenance. It is engineered to replace the o-rings in Peterson 700 series filter housings, restoring a watertight seal that prevents coolant loss and contamination. Boat owners who perform their own engine service will find this kit essential for routine cooling system care.
Each seal in the kit is molded from marine-grade elastomer material selected for its resistance to saltwater corrosion, oil exposure, and temperature variation. The precision-formed profiles maintain consistent compression against the filter housing bore, creating a reliable barrier under the pressure and vibration typical of marine engine operation. Proper sealing prevents coolant bypass, which can lead to overheating and reduced engine efficiency.
This kit fits Peterson 700 Series filter installations found on cruising sailboats, power-driven center consoles, and displacement-hull vessels. Its compact dimensions of 1.75 x 0.35 x 2.95 inches and light 0.04-ounce weight make it easy to store in an onboard tool kit or engine compartment drawer. Basic mechanical knowledge is sufficient for installation, making it accessible to boaters of varying experience levels.
