The Annovi Reverberi o-ring kit for AR70 diaphragm pumps and the Hypro D70 pumps they're based on. It replaces the Hypro 9910-KIT2365. AR is the Italian manufacturer behind Hypro's diaphragm pumps, and with Hypro phasing out its 9910 series parts, this AR kit is the go-to replacement. It includes the o-rings needed to fully reseal the pump during a rebuild.

When should I replace the o-rings?
Whenever you rebuild the pump's diaphragms or valves. Old o-rings flatten and harden over time and often leak once they're disturbed. They're inexpensive, so replacing them during every rebuild prevents leaks and a second teardown.
Does it include diaphragms or valves?
No, it's o-rings only. For a full rebuild, add an AR70 diaphragm kit and, if the valves are worn, the AR2364 valve kit.
Will it fit my pump?
It fits the AR70 and Hypro D70. Other AR and Hypro pumps use different o-ring kits, so check the model number on your pump's tag, or call us.
