• Thread Type :Metric and PG. • Material Data :Halogen-free Nylon PA 66 ( Flammability UL 94V-2 ) for A.C.E.F parts. ( Contact us for Flammability V0 material )Standard in weather-resistant EPDM rubbers for B.D parts. ( NBR rubber is optional for oil-resistance applications )Our black cable glands are suitable for outdoor use have been subjected to UV light exposure and water immersion same as UL746C (f1) rating. UV ( Irradiance 340 nm ) exposure is performed by using a xenon-arc weatherometer for 1000 hours and intermittent exposure to water spray. • IP Protection :IP68 - depending on the less differences between cable diameters & sealing-hole openings. ( Less is Better ) • Working Temp. :- 40 °C to 105 °C ( - 40 °F to 221 °F ). Short-Term to 160 °C ( 320 °F ). • Application :Yongcun’s smart multi-hole cable glands allow several cables water-tightly to be lead through in one gland simultaneously. From Yongcun’s widest variety size choices, no need to use one gland for each wire, so the spaces of wire entry can be reduced to minimize costs & working time
