CSST Manufacturer Fittings Question

[Marshdale007]

Does anyone recognize the manufacturer of this 3/4' CSST natural gas line?

I'm replacing an older Rinnai tankless hot water heater, and once I disconnect the old CSST fitting, it is my understanding that a new fitting must be installed on the end of the CSST line.

The existing CSST line is about 13 years old, but does not list the manufacturer, so I'm not sure which brand of fitting I'll need. The attached photo shows the line with a Trademark, but no manufacturer name.

In many cases CSST fittings can be taken apart and reassembled. Done it many times.
We always use a gas sniffer to check, so for you, at least use soapy water.

I'll check with soapy water and hopefully it will reseal. Thanks.
