Thread specifications: Metric, PG, G (PF) and NPT.
Static temperature: -40℃ - +100℃, up to +120℃ for a short time; Dynamic: -20℃ - +80℃, up to +100℃ for a short time.
Product features:
This intelligent extension spring coil, when extended, can achieve a protective effect similar to that of a sleeve. It can not only achieve waterproof and tensile effects, but also prevent the wire from having a dangerous bending angle. The nickel-plated material is corrosion-resistant and resistant to acids and alkalis. This new concept of a new connector can be applied to all wire outlet fields.
Product materials:
Part A.C.F is made of high-grade copper alloy with nickel plating, and parts B and D are made of high and low temperature resistant silica gel.
Protection level:
Within the specified bayonet range, use an O-ring to fasten the fastening head to IP68 - 5Bar.
