3/64 inch to 1/8 inch walls ± 1/64 inch.
Greater than 1/8 inch walls, tolerances vary.

Wall thickness greater than 1/8 inch are gauged on the
outside diameter tolerance.

Primeline offers natural rubber latex tubing in sizes which range from 1/16 inch inside diameter (ID) x 1/32 inch wall to

How To Determine Tubing Sizes

Calculation Methods:
O.D. (Outside Diameter) =
Inside Diameter+Wall+Wall

I.D. (Inside Diameter) =
O.D.(Outside Diameter)-Wall-Wall

Wall Thickness = (O.D. – I.D.)/2

Standard Tolerances:
Inside Diameter: ± 1/64 inch on sizes up to and including 3/8 inch.
Proportionately greater on larger sizes. 

Wall Thickness: 1/32 and 3/64 inch walls ± .007 inch.
1/16 inch and 5/64 inch walls ± 0.010 inch.
3/32 inch and 1/8 inch walls ± 0.015 inch.
Tubing with walls greater than 1/8 inch walls are gauged by the O.D..
