OEM Part No: RZG020RK
OEM: Clark Reliance
Direct Replacement PN: DLRZ020BRZRK
100% interchangeable / compatible
Summary
The Clark Reliance RZG020RK probe is a gasket seal zirconia insulator based probe used in their EL1800 water column (this is NOT a brazed probe). The stated maximum rating is 1800 psi (124 bar) @ 438 degrees C (821 F). Drumline recommends the use of its DLRZ020BRZRK as an upgrade for the Clark Reliance Probe. The DLRZ020BRZRK is a brazed Zirconia probe that uses a spiral wound stainless steel and graphite gasket, instead of the cheaper gaskets used by Clark Reliance.Key Features

The Clark Reliance RZG020RK probe is a gasket seal zirconia insulator based probe used in their EL1800 water column (this is NOT a brazed probe). The stated maximum rating is 1800 psi (124 bar) @ 438 degrees C (821 F). Drumline does not produce probes that use internal gaskets to create the insulator seal, Drumline only uses brazed insulator joints because they are stronger and far more reliable. Clark Reliance uses multiple part numbers for the same probe, RZG020RK, ZG020RK, ZG020, ZG all refer to the same probe. Clark Reliance probes with model numbers ending in BRZ refer to the newer brazed probe they produce. Currently Clark Reliance are selling both the brazed and unbrazed version of this probe foraround $1000 each. Drumline sell the DLRZ020BRZRK direct replacement for 1/5 of that price.
Drumline recommends the use of its DLRZ020BRZRK as an upgrade for the Clark Reliance Probe. The DLRZ020BRZRK is a brazed Zirconia probe that uses a spiral wound stainless steel and graphite gasket, instead of the cheaper gaskets used by Clark Reliance.
The DLRZ020BRZRK is a direct upgrade for both the Clark Reliance RZG020RK and the RZ020BRZRK. Clark Reliance probes are extremely expensive at nearly $800 each and $25 for gaskets. Drumline can offer a better product at a much more realistic price.
