M-Flex Liner Kits
Standard Liner Kits
Each of our CB/CBF Standard Kits comes with easy to read installation
instructions and a lifetime warranty we take pride in. This lining kit has
been installed in venting applications since 1992 and continues to be the most
popular "all fuels" kit we offer. As you can see there are 3"-8" inside
diameters (ID) as well as 6", 7" and 8" outside diameters (OD). OD Kits
are the same price as ID, just add OD to the end of the part number when
ordering.
