Good oil filtration makes hydraulics last longer - just like engines. Return line is usually preferred - you can use a finer filter. Prince filters come in 10 micron (fine), & 25 micron paper, and 150 micron stainless mesh elements. Heads have internal bypass: 5 PSI suction or 15 PSI return. Elements will replace many other brands with 1"-12 or 1 1/2"-16 threads. NPT ports. Heads and elements sold separately.
NOTE: Prince FB-25 discontinued - use U3L6FE
