Waterproof corrugated pipe joint
What is a waterproof corrugated pipe joint?
Compatible with unslit corrugated tubes (N-GPA Series).
It secures nylon corrugated tubes in precision machinery, switchboards, and similar equipment while protecting cables.
The nylon 66 material provides dustproof and waterproof performance and supports use in cutting-fluid environments.
The purpose of waterproof corrugated pipe joints
The locking clamping ring and special clamping claws secure the nylon corrugated tube and help prevent dust or moisture intrusion.
The threaded design allows easy mounting to wall-mounted corrugated pipe interfaces and similar connection points.
Metric (M), PG, and PF thread options are available for different applications.

About fire protection and flame resistance grade UL94 V-0/V-1/V-2
Test method: Vertical burning test (20mm)
The test sample (length 125±5mm × width 13.0±0.5mm) is held vertically and burned with a 20mm long flame from below for 10 seconds.
If burning stops within 30 seconds, burn it for another 10 seconds.
