Umm, OK. Why? LdeN--or Austin, who knows--went from metal rings to
O-rings--$0.49/ea from MM (maybe the reason)--on the operating pistons
for the later cars. The ones in my BJ8's OD at about 210K miles were
somewhat flattened on the expected side, but still worked.

<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>
