Build your own AN4 oil feed hose

Make your own turbo oil inlet hose

Here you can easily make your own steel braided hose for toubo oil feed. All hoses are crimped in special crimping machines at Speeding, these can not be made yourself at home.

Do this:

1. Carefully measure how your hose should be.
2. Enter the information in this guide. (5 steps)
3. Get a professional machine made hose according to your own measurements.

Step 1 - (Fitting 1 / Fitting 2)

Choose what fittings you want at both hose ends. Drawings of each fitting is available in the pictures.
Swivel means that the fitting can spin around the shaft without twisting the hose.

Step 2 - (Hose length)

Enter the length you want, then enter the "type of measurement" the length refers to.

Step 3 - (Type of measurement)

Step 4 - (Hose type)

There are two different hoses availible.

1. Stainless steel braided hose with PTFE core.
2. Stainless steel braided hose with PTFE core. + nylon braid cover.

All hoses can handle oil forever so there is nothing that will need to be replaced in the future. These hoses are market leading and pass all known tests for steel braided plastic hose that is known today. Since the hoses are have a plastic core, extreme heat can cause the plastic to melt, so be sure to protect the hose closest to the turbo!

Specify if you want the fittings twisted.
In the example below, the fittings are twisted / rotated 90 degrees.
