Do I need to seal the fitting threads before connecting this to my engine block?

Thread sealant or PTFE tape is recommended for any oil line fitting connection to prevent leaks under pressure. Use appropriate strength for oil applications — check your engine's service manual for specific recommendations.

Will this work with both braided and rubber hose configurations?

This kit ships as a complete assembly with 90-degree hose pre-bent and fitted. If you need to swap hose types after purchase, test-fit your alternative hose to the fittings first — verify the 4AN barb or JIC connection matches your replacement hose.

What do I connect to the outlet side of this line?

The outlet fitting accepts standard 4AN male or female connections depending on your oil cooler or filter head setup. Verify your cooler's inlet fitting size and thread type before final assembly to avoid leaks.
