Today they manufacturer a complete line of injection molded polypropylene fittings, which includes male adapters, female adapters, couplings, elbows, tees, bushings and hose adapters. 140°F—32 °F @ 75psiMaximum continuous use temperature for a material is typically derived from a testing procedure developed b y Underwriters Laboratories, In c. The UL temperature index is reported for three different categories: electrical, mechanical with impact, mechanical without impact. The evaluation for each category represents the temperature at which specific properties will decrease to ½ of their original values after 60,000 hours of exposure. These guidelines should not be used as specific limits or used alone to determine suitability for end use. It is impossible to anticipate all factors that can influence the maximum and minimum continuous temperature. Therefore, Green Leaf inc. can make no guarantee of results and can assume no liability in cfonnection 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
