Plastic Corrugated Tubing Quick-Connect Fitting
GQTF-AD
Product Overview
Plastic Corrugated Tubing Quick-Connect Fitting
In high-volume wiring projects, the speed of each connector installation directly impacts the overall schedule. The GQTF uses a push-in quick-connect design — align the corrugated tube, push it in, and it locks instantly. No rotation, no tools required. When you are installing hundreds of fittings on an assembly line, that difference compounds into significant time savings.
Made from halogen-free UL94V-2 PA66 nylon, rated for -40°C to 100°C operation. Available in equal-bore and reducer configurations to handle same-size tube extensions and cross-size transitions. The distinctive profile makes it a widely adopted choice for CNC machining, machine manufacturing, electrical installations, and automation equipment.
Key Features
- Push-in, tool-free installation: Insert and lock in one motion — dramatically reduces per-fitting installation time on high-volume wiring jobs
- Equal-bore and reducer types: Handles same-size tube extensions and diameter transitions in one product family
- Halogen-free UL94V-2 nylon: Flame-retardant and environmentally compliant for industrial equipment wiring

Application Scenarios
CNC Machinery & Machine Manufacturing
High-volume wiring lines benefit most from push-in fittings — each connector installs in a fraction of the time compared to threaded types, significantly reducing total assembly labor.
Electrical & Engineering Installations
Reducer types simplify on-site tube transitions. Faster installation and flexible sizing reduce project cycle time and labor cost on large electrical wiring jobs.
Automation Equipment Wiring
Tool-free push-in installation improves throughput on automation assembly lines. Less manual dexterity required means fewer errors and faster operator training.
FAQ
Q1｜What is the difference between the GQTF quick-connect and the GWTF-AD waterproof coupling? How do I choose?
The GQTF prioritizes installation speed — push-in design for fast, tool-free assembly, best suited for general indoor industrial wiring where high-level waterproofing is not required. The GWTF-AD waterproof coupling (IP68/IP69K) is engineered specifically for enhanced sealing, suitable for outdoor, wet, or high-pressure washdown environments. If your application does not require IP68 protection, GQTF delivers higher installation efficiency; if waterproof sealing is needed, choose GWTF-AD.
Q2｜Is the push-in locking mechanism strong enough? Will the tube pull out?
The GQTF uses a specialized clamping structure that locks the corrugated tube upon insertion. This provides sufficient holding strength for standard industrial wiring applications. If your application involves strong pull forces (e.g., cables in frequent motion or dynamic environments), consider the waterproof coupling (GWTF-AD) or a long-thread type fitting for additional mechanical strength.
Q3｜How do I determine whether I need equal-bore or reducer type?
Check the outer diameter (OD) of each corrugated tube segment to be joined. If both ODs are the same, select the equal-bore type in the matching size. If the ODs differ, select the reducer type that corresponds to both OD dimensions (e.g., AD13 to AD21.2). Refer to the engineering drawing on this page or contact our sales team with your tube specifications for sizing assistance.
Q4｜The material is rated UL94V-2 — can it be used in UL-certified equipment?
UL94V-2 is a UL flame-retardant certification grade that meets the basic wiring material safety requirements for most industrial equipment, including many North American and EU market devices. If your equipment requires a specific flame class (such as V-0) or UL certification documentation, contact our sales team for material certification details.
Q5｜Can the GQTF be used alongside other Good Gi corrugated tube fittings or cable glands in the same system?
Yes. The GQTF is sized by corrugated tube OD and is compatible with Good Gi corrugated tubes and other brands of the same OD. In a mixed wiring system combining quick-connect (GQTF) and waterproof (GWTF-AD) fittings, you only need to ensure consistent tube sizing at each connection point — different fitting types can be used at different segments based on the local environmental requirements.
