<div>Years ago I made an accumulator piston to use an O
ring.
<div>The result was an abject failure as tiny chunks of
the O ring were sliced off each time it passed over the pressure
relief drillings in the housing.</div>
<div>Any clue as to how that has been overcome?</div>

<div>I have the DWM 'uprated' accumulator set; the housing has an
O-ring and the piston has four equally-sized metal rings. Don't
recall any others, but don't think it was any different than the
OEM one I took out.<br><br>
Too late now, but had I known of it I might have bought the AH
Spares version with O-ring(s?) on the piston instead of metal
rings. The metal rings will score the accumulator bore
eventually.<br><br><br><br><div>On 6/21/2023 7:35 PM, John Spaur via Healeys wrote:<br></div>

four narrow to make up two ring sets for the piston?</p>
