The cutter isn't motorized? That's too difficult. The adbv seals to the solid steel end cap, and the bypass valve seals in what looks like a rubbery material on the inner circle of the other end cap? If so, that is good construction IMO. I have this same one ready to use on the Toyota Prius, usually I use the longer variation, but no worries here. I wonder why they make so many holes on the inlet of this small filter, yet on some of the larger filters they put fewer holes? Glad to see one cut and good pics posted.
Actually I just looked inside my same filter, and the bypass valve is surrounded by a ring of the rubbery material. I thought it was glue, but now see it is the end cap design. That's a good seal.
