OrbitWaterMaster Underground 57473 Diaphragm, Jar Top Black

I ordered this for an old valve repair. The new ring did not fit in the housing but the membrane seems OK. Did not try the repaired valve

Take out the old, put in the new, walla!! No leaks! If you have an old (20 plus) Orbit sprinkler system, with the 'old' valves this diaphragm ROCKS.

Stopped the leaks from the jar top sprinkler heads.

This item fit perfect into the sprinkler valve.

Kept having leaks appear within my system, could not understand why, so I took a shot, ordered the seal kits and installed 4 kits into 4 manifolds and no more leaks.. Very happy with the product.
