100シリーズバルブダイヤフラム（逆流防止機能なし）57045

Fixed a leaking valve in about ten minutes with this diaphragm, and the fit on the 3/4 in. internal bleed body was spot on. The rubber feels thick enough to actually last a few seasons instead of cracking like the old one did.

Swapped this into my 1 in. internal bleed valve in about five minutes and the zone stopped weeping completely. The rubber seats flush just like the original, no leaks after two weeks of daily watering.

Wasn't sure a $10 piece of rubber would fix my sticking valve, but it seated perfectly on the first try. Ten minutes with a screwdriver and the zone runs dry again instead of dribbling all night.
