GM 10253680 Heater Hose Insulator


This is a new, 100% accurate reproduction of the GM 10253680 heater hose insulator/washer. It's made of black EPDM rubber that's designed for under-hood use. Your GM vehicle used two of these insulators to attach the heater hose assembly to the firewall. The price listed here is for a single insulator - please be sure to add two to your cart if you need a complete set. Note that this part is obsolete from GM and is no longer included with the 10256543 and 10256544 heater hose assemblies. We also have the 22536997 attaching screw.
