Maximum and Minimum Continuous
Use Temperature
Maximum continuous use temperature for a material is typically derived
from a testing procedure developed by Underwriters Laboratories, Inc.
The UL temperature index is reported for three different categories: electrical,
mechanical with impact, and mechanical without impact. The value
for each category represents the temperature at which specific properties
will decrease to 1/2 of their original values after 60,000 hours of exposure.
Minimum continuous use temperature for a material must be based on the
property requirements of the end use product. Properties such as: Tensile
Strength, Elongation at Break, and Yield Strength are published down to
-40˚F in some cases.
We have taken the above information into consideration and developed
the following guidelines for use with Green Leaf, Inc ® Proprietary fittings
(not including GatorLock ® Cam Lock Couplings and Valves):
Nylon 6/6 Fittings:
Polypropylene Fittings:
167˚F—32˚F @ 75psi
140˚F—32˚F @ 75psi
These guidelines should not be used as specific limits or used alone to determine
suitability for end use. It is impossible for Green Leaf, Inc® to
anticipate all factors that can influence the maximum and minimum continuous
use temperature. Therefore, Green Leaf, Inc ® can make no guarantee
of results and can assume no liability in connection with the use of this
information. Confirmation of the validity of this information and the suitability
of our products for any specific end use should be attained independently.
