PF35W is one of the three elementary conduits used in the composite Fx176 Herschel conduit. It converts an input pi-heptomino into an output wing in 35 ticks.

In November 2017, Aidan F. Pierce discovered the compact PF35W variant shown in the infobox, which improved the repeat time of the Fx176 to 73 ticks and allowed gliders from following dependent conduits to escape freely. A previous non-Spartan PF35W variant had permitted a repeat time of 75 ticks, but did not allow a following dependent-conduit glider to escape.

Several variants of the new key catalyst are known, including welded additions for the Fx176 that absorb the following Herschel's first natural glider, since a standard fishhook eater doesn't quite fit. An eater 5, sidesnagger or dependent conduit can also be used instead of a weld.

The pi output is symmetrical, and the new PF35W can connect to it in either of two mirror-image orientations (unlike the original PF35W). This means that an F176 conduit is equally possible, also with a 73-tick repeat time.
