This hose takes water from the water pump back towards the car heating system and is located directly underneath the oil filter.
Every time the oil filter is changed, inevitably some oil drops onto the hose. This causes the OE rubber hose to degrade. It will go soft, balloon under pressure, and eventually, burst.
Our solution is a hose that is protected from oil and other chemicals, outside as well as inside (Fluro silicone inner and outer).
