SEE REPLACEMENT PART: OBSOLETE

The Laing Housing O-Ring 909 is a sealing component used with compatible Laing pump housing applications. O-rings are small parts, but they are often essential to stopping leaks after a pump has been opened for inspection, rotor replacement, cleaning, or other service. Reusing a flattened or stretched seal can create avoidable water seepage, so replacing the O-ring during pump maintenance is a practical way to support a better repair. Match the Laing 909 reference and part number 7997 to the original seal before installation.
