| *Property specifications of Caplugs parts are subject to change without notification. |
| DIMENSIONAL TOLERANCES* |
| Caplugs parts are designed in accord with functional dimensions and will perform to dimensions listed in this catalog. In view of the flexibility and stretch of most of the materials used in Caplugs parts, it is recommended that the following tolerances be used for checking purposes, especially by those unfamiliar with measuring this material. |
| **Independent Third Party Testing supports our published claims of Flex500PLUS successfully performing under intermittent service temperatures of over 500º F. |
Tolerances for Inch dimensions given to three decimal places.
±.010’’ per each inch of length. Minimum is ±.010’’ where dimension is less than one inch.
Examples:
Tolerance for .750’’ dimension is ±.010’’
Reason: Although .750’‘x ±.010’’ = ±.0075’‘, ±.010’’ is the minimum. Tolerance for 1.000’’ is ±.010’‘.
Reason: 1.000’‘x±.010’’ = ±.010’‘. Tolerance for 1.500’’ dimension is ± .015’‘.
Reason: 1.500’’ x ±.010’’ = ±.015’‘. |
Tolerances for Inch dimensions given to two decimal places.
±.020’’ per each inch of length. Minimum is ±.020’’ where dimension is less than one inch.
Examples:
Tolerance for .75’’ dimension is ±.020’‘.
Reason: Although .75’’ x ±.020’’ = ±.015’‘, ±.020’’ is the minimum. Tolerance for 1.00’’ dimension is ±.020’‘.
Reason: 1.00’‘x±.020’’ = ±.020’‘. Tolerance for 1.50’’ is ±.030’‘.
Reason: 1.50’‘x±.020’’ = ±.030’‘. |
Tolerances for metric dimensions given to two decimal places.
±.25mm per each 25.40mm of length (.01 mm per mm). Minimum is ± .25mm where dimension is less than 25.40mm.
Examples:
Tolerance for 19.00mm dimension is ± .25mm.
Reason: Although 19.00mm x ± .01 is ± .19mm, .25mm is the minimum. Tolerance for 25.40mm is ± .25mm.
Reason: 25.40mm x ± .01mm = ± .25mm. Tolerance for 38.10mm is ± .38mm.
Reason: 38.10mm x ± .01mm = ± .38mm. |
Tolerances for metric dimensions given to one decimal place.
± .5mm per each 25.4mm of length (.02 mm per mm). Minimum is ± .5 where dimension is less than 25.4mm.
Examples:
Tolerance for 19.0mm dimension is ± .5mm.
Reason: Although 19.0mm x ± .02mm = ± .38mm, ± .5mm is the minimum. Tolerance for 25.4mm dimension is ± .5mm.
Reason: 25.4mm x ± .02mm = ± .5mm. Tolerance for 38.1mm dimension is ± .76mm.
Reason: 38.1mm x ± .02mm = ± .76mm. |
