And I've developed a safe, surefire method to replace diaphragms with new aftermarket on the plastic slide 250's. A good USA source for the new...but a tricky process nonetheless.....the factory uses a glued "cap" to ahem, capture and seal the diaphragm.
The rebuild requires removing/destroying the cap...while leaving the "2nd deck" (also plastic) intact.

Very carefully using a dremel with cutoff, I've developed a safe removal procedure, requiring taking them off piece by piece.

The well structured new diaphragm (not even listed for the 250!) has a center "tire" which replaces the cap and offers excellent sealing capability.

It is then glued and sealed, as was the factory diaphragm rubber.

Its a very tricky process, but effective as new diaphragm/slides are quite expensive.

So...within my service, I'm now stocking diaphragm rubbers for both EX250 and 500. Keep that in mind, folks.
