Do you have a question about this Accessories and Part?

Is The Metric-To-Standard Brake Line Tee Included In The Second Motor Home Kit For F-53 Chassis?
If your motorhome brake line has metric fittings, it will be necessary to use a metric-to-standard T-fitting to attach the proportioning valve. This fitting is not supplied in the RoadMaster BrakeMaster Second RV Kit for Hydraulic Brakes # RM-98300. Before you install the kit, you need to identify the size of the metric brake line. If it is 10mm you can use the Roadmaster Metric-to-Standard Brake Line Tee # RM-7923. If it's 12mm, you can use the Roadmaster Metric-to-Standard Brake Line...

Metric Brake Line Fitting to Use Roadmaster BrakeMaster System on Ford Econonline Van
The fittings that are included with the Conversion Regulator Kit for # RM-9060, part # RM-900001, includes standard fittings but not metric fittings or adapters. You would need # RM7921.

Metric to Standard Brake Line Adapter Recommendation
We don't have any metric brake lines, but we do have some metric to standard adapters that could work for you. The part # RM7921 will work for a 12 mm brake line and the part # RM-7923 will work if you have a 10 mm thread. The brake line # BH-3MFS-3-5 that you referenced is 3-1/2 feet long too.
