It ensures a tight, leak‑free connection between coolant hoses that help maintain optimal DEF temperature. Commonly found on Freightliner and Sterling trucks equipped with selective catalytic reduction (SCR) systems, this nylon connector handles the flow of engine coolant to the DEF tank or doser unit. Replace it if the original is cracked, leaking, or missing to keep your emissions system functioning properly.
