These are "heavier duty" than standard N Series Black Polypropylene Camlocks. They feature a thicker body and fiberglass reinforcement fibers for added impact/crush resistance; it should be noted that black polypropylene camlocks are still relatively easy to crush or break so special precaution when crimping/assembling should be used. Always close both coupler arms in an even manner at the same time when engaging. They are typically used in certain suction/low pressure discharge chemical applications where polypropylene is the best suited material. All types of camlocks are NOT for use with compressed air or gases, and polypropylene dust caps and plugs should not be used in pressure applications. The rated working pressures at 20°C (70°F) are: 1/2" to 1" sizes 100psi, 1-1/2-2" is 75psi, 3" is 50psi, and 4" is 50psi. As a guide only, polypropylene may be suitable for -26°C (-15°F) to +93°C (+200°F) (WATER) but rated working pressures drop significantly with polypropylene camlocks. **Polypropylene are low pressure rated camlocks. Special precaution must be taken when using with chemicals at elevated temperatures and/or pressures - consult factory. Always confirm if gasket material is compatible with fluid.

Temperature Range: As a guide only, polypropylene may be suitable for -26°C (-15°F) to +93°C (+200°F). Always confirm if gasket material is compatible with fluid & temperature.

Detail Comments: In the 1/2" & 8" sizes there is no international standard; however, there are 2 standard interchanges in North America. The most common is the PT interchange, however, there are also separate Ever-Tite/Andrews/Dixon/Bayco patterns.
