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>
