Nylon Corrugated Tubing Quick Fitting – Female Thread
GITF-AD
Product Overview
Nylon Corrugated Tubing Quick Fitting – Female Thread
The GITF-AD combines two time-saving features in a single fitting: female (internal) threads that screw directly onto male-threaded equipment ports — no adapter required — and a clamping jaw structure that locks the corrugated tube the instant it is pushed in. No tools, no rotation of the tube, immediate secure lock. Ideal for automation equipment and machine wiring engineers who value assembly speed without sacrificing retention strength.
Made from halogen-free UL94V-2 PA66 nylon. Static operating temperature -40°C to 100°C (peak 120°C), dynamic -20°C to 80°C. V-0 upgrade available for high-safety applications. Standard color black; custom colors on request.
Key Features
- Clamping jaw instant lock: Push the corrugated tube in — the jaws grip automatically with greater force under tension; no tools needed
- Female thread direct mount: Threads onto male-threaded equipment ports without an adapter for cleaner mechanical integration
- Halogen-free UL94V-2; V-0 upgrade available: Flame-retardant and compliant; upgradeable for high-safety-class devices

Application Scenarios
Automation Equipment & Machine Wiring
Push-in clamping jaw installation removes the need for tools on the assembly floor. One push locks the tube — speeds up wiring work on automation equipment and simplifies maintenance.
Control Panels & Distribution Systems
Female thread mounts directly onto male-thread ports in control cabinets. Combined with the clamping jaw, it delivers secure tube retention at multi-point wiring entry positions.
Industrial Machinery & Factory Wiring
The high pull-out resistance of the clamping jaw structure keeps corrugated tubes locked in place even under mechanical vibration, maintaining reliable cable protection long-term.
FAQ
Q1｜What is the difference between a quick-connect fitting and a standard threaded fitting?
A standard threaded fitting requires manual rotation to tighten the corrugated tube. The GITF-AD quick-connect uses a clamping jaw — push the tube in and it locks automatically, no tools required. Especially valuable in automation equipment wiring or large-scale installations where many fittings need to be installed quickly or where maintenance requires frequent re-wiring.
Q2｜How strong is the clamping jaw? Can the tube be pulled out under load?
The clamping jaw features a self-reinforcing grip — the harder the tube is pulled, the tighter the jaws clamp onto the corrugated tube's outer wall. This provides reliable pull-out resistance for standard industrial wiring. For extremely high pull-force requirements, contact our sales team or consider a threaded-lock type fitting.
Q3｜Which equipment interfaces is the female-thread type compatible with?
The GITF-AD has internal (female) threads and is designed for equipment with external (male) threaded ports — such as machine housings or structural members with threaded tube ports. Before ordering, confirm the thread type (Metric) and size on your equipment port, then verify it matches the fitting's internal thread specification.
Q4｜The standard rating is UL94V-2. Can it be upgraded to V-0?
Yes. UL94V-2 is the standard flame-retardant self-extinguishing grade. UL94V-0 extinguishes faster and produces no flaming drips — preferred for high-safety power devices, medical instruments, and applications requiring fire safety class certification. Confirm your equipment's fire safety requirements before ordering.
Q5｜How do I select the correct tube size for GITF-AD?
Selection is based on two criteria: ① The corrugated tube outer diameter (OD) must fall within the clamping jaw's applicable range — refer to the engineering drawing. ② The equipment port thread size must match the fitting's internal thread specification (e.g., M20, M25 Metric). Contact our sales team with your tube model and port dimensions if you need sizing confirmation.
