Put the year and model number of your vehicle in your info and also post it when you ask questions.

See post 2 in the below thread. The rounded bulbus male end I have only read it refried to as an Acorn. However, that is a shop name. Nothing in my 18 years as a diesel mechanic in my experiences uses those but Mercedes.

I have seen a Choline chart where they sold the fittings but don't remember the real name for it.

The threaded end on the Oil Cooler is referred to here on the forum as the Oil Cooler nipple.
The Nipples used to repair the oil cooler nipples are actually the fittings at the base of the Oil Filter Housing that the Oil Cooler Hose screws onto. They have a name and are called screwed nipple.

Oil cooler nipple size and pitch

The ones in the attached picture were listed as conical hose nipples in a catalog. It sells Choline products (Choline Oil Cooler Hose is used on many aftermarket oil cooler hoses including the ones for Mercedes).

Good morning,

I don't have a Mercedes but I do have a large cooler in great shape I removed from a car in a salvage yard many years ago. I thought I would use it on an old BMW I am renovating. The local hydraulic shop said he could re-use the fittings from the old lines and I found the metric beadlock o-ring fittings I need to fit the adapters on my oil filter canister.

Cooler is too nice not to use but maybe I should re-consider and look at using a new cooler with generic AN fittings. I guess I could always sell it on ebay.

Thanks for the help, Diesel911!

I don't own a Mercedes but I pulled a large cooler out of a salvage yard years ago along with the lines I thought I could use on one of my old BMWs.

The cooler is in great shape and I found the metric female beadlock o-ring fittings that will fit the OEM oil filter canister that I will install on the car. Hydraulic shop said he could re-use the MB fittings and make up new lines for me.

I guess I could purchase a new generic cooler but this Behr unit is large and cleaned up well.
