Flexible Liner - I.D. or O.D.??

[Rob From Wisconsin]

A question I'm sure that's been asked before, but for me, it's perhaps criticle.

When a Mfr. spec's a 6" dia. liner, are they talking "inside" or "outside" diameter??

Thanks..

Inside.

Ok, with that being said, what would the typical addition to the I.D. to get the O.D. on flex liners??

Usually around 3/8" depending on what brand.

It actually depends and you should contact the manufacturer... I know of a manufacturer that makes all of his liner 6" O.D. .... It is all based on the type of mandrel the company is using..
