*OTHER COLORS ARE AVAILABLE IN THESE MATERIALS UPON REQUEST.

**FLAMMABILITY TESTING:
Our suppliers classify their raw materials (based on the UL 94 Standard Tests for Falmmability of Plastic Materials) as follows:

[All classifications are per ASTM test methods for the raw material only (not the finished product).]
--Materials classified as 94 HB, meet requirements of the Horizontal Burn Test for classifying materials.
--Materials classified as 94V-2, 94V-1, or 94V-0 meet requirements of the Vertical Burn Test for classifying materials.
(with 94V-2 as the least stringent classification, and the 94V-0 as the most stringent or highest classification for this test)

***Due to the flexural modulus properties of other nylons, 1 5/8" and 1 7/8" I.D. sizes are available only in Nylon 6 Copolymer (09).

Square peak/Square valley provides increased crush resistance.
Square peak/Round valley provides an increase in flexibility.

All dimension tolerances on this chart are +/- .015"/.381mm
Typical outer wall thickness–Peak (.008" - .020"/.203mm-.508mm) Valley (.012" - .025"/.305mm-.635mm)
All dimensions are based on OEM drawing #'s BST-0056 and BST-0057.
