ASTM test methods apply. Caps'n Plugs cannot be held responsible for the accuracy of these figures.
* = Hydrocarbons will cause thermoplastic rubber to swell if soaked; it will not affect the properties. It is resistant if only splashed with hydrocarbons.
-
Tolerances on all decimal dimensions ±0.010 per inch.
Example: 1.000 ±0.010 = 0.010"
Example: 2.500 ±0.010 per inch = 0.025"
- Tolerance for fractional dimensions ±1/32" per inch.
