B Series Flange O-Ring

Replacement O-Ring for B series Upper Water Neck Flange and/ or any products fabricated using said flange. You can either purchase these Dash 130, 131, and 132 o-rings or try to find them locally. NOTE: If you plan to look for your own, ensure the material is compatible with Ethylene Glycol. The o-rings come in a set of three as a result of multiple changes that have been made to the flange and its o-ring grove over the years and being to difficult to identify which generation customers own, so you get all of them!
