The only time I've seen a filter like this fail to seal is when they are not tight or if the seal was not oiled to prevent bunching and tearing. 25 NM = 18 lbs/ft

If it's leaking around the top of the bolt on to the top of the housing, then it's leaking due to lack of proper torque or bad washer. Usually the washer can be used more then once without problems. I have seen these type of fittings (banjo) that have a score under the bottom of the bolt head or on the fitting and cause leaking, which no amount of tighting can prevent. I also have seen some of these type of fittings have a steel washer used by mistake on occasion, and they will leak as mine did when I bought the car. The PO or tech had used a steel washer instead of copper washer on the car and it would leak. I just went to a local and bought several to have just in case.
