Can i use rubber hose for transmission cooling lines? Indeed, you can but you must ensure it is the proper size and rated for use.
Rubber hoses are comparatively cheap and safe. Transmission rubber pipes are different from other rubber line variants because they have to endure the fuel pressure for a long time.
A rubber tube is easy to use among aluminum, steel, or nylon braided hoses. It lasts a long time, and the users are satisfied with this. This article gives you the necessary information about the appropriate rubber line for your automobile transmission cooler.
Can I Use Rubber Hose For Transmission Cooling Lines? Is It Safe?

Why Use Rubber Hose For The Transmission Cooling System?
- Comparatively cheap
- You can get a rubber hose nearby a hardware store
- Easy to install to the transmission
- Convenience to use
Rubber hose can’t take too much heat and chances to damage the line. That’s why it should be away from the exhaust and other hot types of machinery.
Note: If you have high performer vehicle, the rubber hose can’t be a long-lasting solution. You should use a metal hose and AN fitting.
What Kind Of Rubber Hose Is For The Transmission Line?
Not all rubber hose is appropriate for the trans line. Ordinary rubber melt over on excess heat of the radiator and engine. So, when you look for the specific rubber hosepipe in your nearby shop, check some specific issues.
Rated For Transmission
The rubber hose rated for trans is used for the transmission line. You can see the word “transmission” is printed on the hose. The other varieties of rubber can melt and leak because of heat.
3/8” Size With 10 Miter Length
The appropriate size of a trans cooler line is 3/8”. Most of the time, 5/16” won’t fit and get small for the cooling line. So it is better to buy the 3/8” size line. It’s also 10 meters in length. There is an ID (inner diameter) and OD (outer diameter) of the hose. Make sure about the diameter of it.
Rubber Line Can Take Minimum 150 PSI Pressure
A transmission cooler rubber hose can endure a minimum of 120-150 PSI of hot fluid pressure from the transmission. Generally, the cooler hose pressure should remain around 30 PSI. More than 70 is alarming. Ordinary rubber tubes can’t take this pressure and leak quickly.
Barb And AN Fittings
There are two types of fittings for the rubber line: Barb and AN fitting. Barb fitting is a standard push-fit for the rubber transmission. It’s easy to fit and cheap. For more security, use double fuel injection clamps.

Frequently Asked Questions (FAQs)
Can I use a fuel hose for the transmission line?
No, you should not. Some people install a fuel hose in the cooling transmission line instead of a transmission rubber hose. Some may be lucky that they found no issue or problem with it. But in most cases, there is a chance of an accident. The fuel hose is less thick than the rubber hose and does not take much pressure. Using a rated trans rubber hose for this cooling line will be wise.
Are transmission cooler lines high pressure?
Not entirely. A transmission cooling line has around 20-30 PSI pressure during operation. But it can take up to 150 PSI pressure. And remember, 70 PSI is frightening for your vehicle. Also, remember that the higher performer your vehicle, the more pressure your transmission.
What kind of hose can I use for transmission fluid?
You can use a PTFE hose for transmission fluid. It’s used as a liner of the rubber hose. A good quality hose of shock-resistant and temperature resistant. Also more durable for any chemical reactions.
What size are transmission cooler lines?
The useful size is a 3/4” hose for the transmission cooling line. But there are 5/16” sizes also available. These pipes are generally 10 meters long. The ID and OD have differences. Buy fittings according to the ID.
Final Words
Do you have any questions about using a rubber hose for transmission cooling lines? Hopefully, no. The rubber hose is secure and tolerable to a lot of heat. Its DIY work is to set a rubber pipe for a cooler system of a vehicle.
Moreover, you can save your budget for hardware and maintenance. Experienced folks are satisfied with using rubber lines in their automobiles. In general, it is okay to set the rubber for transmission but find other metal for hard and heavy runs.
