Thanks, jackĢ005 E150 4.6If you have new OEM hoses from Ford they'll have the associated ancillary parts as well. Where can I find an o-ring kit for new OEM heater hoses? They are not included with the hoses. It is probably the book that Ford engineers consult as well. This is an area of my expertise and I have found this book to be very helpful. Though I respect many Ford choices with regards to their truck engines, unfortunately these quick connect heater hose fittings are a poor design choice.įor further information on the properties of rubbers, I refer you to Schweitzer's book 'Mechanical and Corrosion Resistant Properties of Plastics and Elastomers ', chapter 4.

Nor can one guarantee that the clip will hold, but if the fitting was removed carefully, it should. Of course, one can never guarantee that they were manufactured properly or that the packaging is accurate, but that is always the case for almost anything. Fortunately, standard nitrile plumbing O rings are rated compatible for the temperatures and fluids encountered in this application. To replace these hoses or seals, it is necessary to improvise a compatible replacement. It is impossible to find some of these parts from aftermarket sources as well. They do not sell the hoses, the quick connect assemblies, or the O rings. OP you'll need to visit the dealership to obtain the correct size and compound of the seals you need, also check into obtaining the locks holding the OEM connectors to the heater core tubes.Unfortunately, The original heater hose equipment is no longer available through the dealer for many of the older truck engines. No that's not true at all-household plumbing parts are not compatible with automotive uses.
