Beginning in July 2020 we will replace P/N 510-017 O-ring with P/N 510-018 O-ring in the 455 Balanced Regulator and KM Diamond and associated kits. This O-ring is found in the SuperFlow® 450, 455 Balanced Regulator and KM Diamond adjustment knob/packing assembly. We have found an enhancement in using the new P/N 510-018 O-ring in creating a more positive seal. Any remaining stock of the P/N 510-017 O-ring can be used without issue.
Please contact your authorized KMDSI dealer or e-mail [email protected] for more information.
