got a 21.3 mm line, is this the right clamp size or am i thinkin about that backwards

Question by: Gary R on Dec 7, 2025, 8:01 AM

For a 21.3 mm outside diameter, the 21.3 mm size clamp is the match. The note on these clamps is that mm size times 0.03937 gives you the inch size, so 21.3 mm works out to about 0.84 inch OD.
