Only dimensions shown in photo are machined down during manufacturing, to ensure a smooth fit.
If opposing OD/ID's are used, edges may not be smooth; therefore, fitment is not guaranteed.
Advertised OD/ID's are guaranteed. We cannot guarantee the presence of indents as shown
and/or indent/expansion points may not be centered.
Product is man-made and no two items will be exactly identical,
although, every effort is made to ensure a consistent and quality product.
