Primeline’s natural rubber latex tubing meets or exceeds the physical properties of Commercial Item Description A-A-52047C Type I Class 1, 2, and 3, Type III, Type IV, and Type V Class 1, 2, and 3 which replaced Federal Specification ZZ-T-831D.

Primeline’s amber natural rubber latex tubing is in compliance with USP Biological Classification IV.

Standard Tolerances:

± 1/64 inch on sizes up to and including 3/8 inch.
Proportionately greater on larger sizes.

1/32 inch wall ± .007 inch.
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
1 inch ID x 1/4 inch wall.

Primeline Industries supports the world-wide goal to eliminate the use of ozone depleting chemicals. We do not knowingly use a Class I or Class II ozone depleting chemical as identified in the U.S. Clean Air Amendments of 1990 in the manufacturing process of our natural rubber latex tubing.

How To Determine Tubing Sizes

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..
