Micro ducts are small diameter conduits ranging from 3-16 mm outer diameter (OD) that provide a pathway for fiber cables. Our Micro duct Connectors are designed to provide simple, 2-click plug-and-play coupling of micro ducts, enabling longer runs and excellent pushing/pulling performance. The micro ducts to be linked with can be either of the same outer diameter (OD), or of different OD using hybrid Micro duct Connectors.
Micro duct connectors and enclosures contribute to link your micro duct conduits. It’s designed to easy-to-install and disconnect with lock and nut, or plug-and-play mechanism. Transparent, it allows you to visually inspect micro cables passing through during installation.
Micro duct connectors and enclosures are used for coupling micro-ducts together fast and easily, with just push/pull or plug-and-play mechanism. Simply push the micro ducts into the centers of the coupling and no special tools are required.
Micro-duct Connectors come in four different versions:
This is the Micro duct Straight Connector . Straight Connectors are used to join sections of micro-ducts.
This is the Micro duct Push Fit Reducer Connector. Reducer Connectors are used to join micro-ducts of different dimensions.
This is the Micro Duct Connector End Stop. It’s Round with Clear Body. End Stops are used to block open duct ends and prevent water and dirt from entering the micro-duct.
This is the waterproof air/ gas block micro duct connector. The gas blocks (water blocks) are normally used between indoor and outdoor environments to prevent air flow that may result in condensed water getting into ducts.
Micro duct connectors have so many advantages that I can introduce to you. Such as:
1. Easy “Push-In” Installation
2. Simple, 2-click plug-and-play coupling, no special tools required.
3. Transparent Plastic Body, Easy to observe the situation inside the connector.
4. Secure Mechanism
5. Secured by locking rings or nut to prevent accidental removal of connector.
6. Airtight And Waterproof, Connections are watertight up to 5 meters below water surface.
7. High Environmental Resistance
8. High temperature resistance minus 45 to 50 degrees
10. High pressure resistance greater than 25 bar.
11. Long Service Life, Useful life for at least 25 years

2026 selection update: start with the duct interface and sealing duty
A اتصالدهنده میکروداکت is selected by duct OD and geometry, sealing duty and the installation environment. A push-fit mechanism does not remove the need to check cut quality, insertion depth, retention and the completed route test.
| Buyer question | Evidence to capture |
|---|---|
| Same or different sizes? | OD at each port and straight, reducer, branch or end-stop geometry. |
| What must be sealed? | Air, water, gas, dust or only mechanical continuity, plus the test method. |
| Where is it installed? | Chamber, cabinet, direct burial, indoor route, temperature and access. |
Use the site’s اتصالدهندههای میکروداکت range to shortlist the part, then compare the drawing with the measured duct. If a run leaks or blocks blowing, inspect the joint before changing machine settings.
Can one connector fit every microduct?
No. Confirm OD, tolerance, wall condition, seal range and the approved drawing for the exact connector.
What does push-fit change?
It describes the installation mechanism; it does not replace inspection of sizing, insertion, retention or leak performance.
What should an RFQ include?
Include duct OD and wall, connector geometry, environment, sealing requirement, quantity and the continuity or leak-test method.
Frequently asked questions about microduct connectors
What does a microduct connector join?
It joins compatible microduct sections, connects different approved sizes through a reducer, or closes an open end when the selected design supports that task.
Does push-fit mean that no inspection is needed?
No. Push-fit describes the installation mechanism. OD, cut quality, insertion depth, retention and leak testing still need to be checked.
How can an installer find an air leak?
Isolate the test section, confirm all ends are closed, stabilise the test condition, inspect each joint and repeat the test after one change at a time.
Can one connector fit every microduct?
No. Confirm outside diameter, tolerance, wall condition, seal range and the manufacturer’s approved drawing.
Why can a connector cause fiber blowing trouble?
An incorrect size, damaged seal, incomplete insertion or misalignment can disturb the air path or create a physical snag point.
خواستهٔ نقل قول باید شامل چه مواردی باشد؟
Include duct OD and wall data, connector type, route environment, pressure or leak-test method, quantity and any cover, clip or end-stop requirement.

Summary
Microduct connector selection begins with measured duct interfaces and a clear sealing duty. Choose the geometry for the route, prepare each duct end carefully, seat and lock the joint, then test the completed section. If air escapes or a cable stops, check sizing, insertion, alignment and route continuity before replacing parts. This turns a simple definition into a practical engineering and procurement guide.
