This filter housing is generally well built but suffers from overly sloppy connections that require more than just wrapping teflon tape around each thread. Once installed, the case did not cause any problems after 3 years of use, apart from the non-standard gasket size. Replacement seals are extremely difficult to find and the manufacturer rarely lists their actual size. But I finally found one that fits: Uxcell Nitrile Rubber O-rings, 145mm OD, 135mm ID, 5mm wide, Metric Buna NO-Ring, 5-pack.
