Proflow's Oil Breather / Catch cans are specially designed with a quenching plate to cool hot oil vapour and turn it into a liquid so it can be collected in the base. It comes with a washable stainless screw on filter with o-ring to stop it coming loose with vibration. The high volume tap allows quick draining and is threaded for attaching a barbed adaptor and hose for hard to get to installations. Has AN12 male top port and two female AN10 ports.
