MICRODUCT CONNECTORS

Microduct reducer coupler for different-size duct connections

This microduct reducer coupler is presented for connecting two microducts with different outside diameters, such as a direct-buried-to-indoor transition.

The source lists FPG reducer codes, push-fit technology, pre-installed safety clips, IP68 protection and a maximum working-pressure statement. Confirm both tube dimensions, the correct tapered-hole code and the route test conditions before ordering.

SELECTION GUIDE

Choosing a reducer coupler for a duct transition

Use these checkpoints to prepare a product-specific enquiry and close the fit, test and documentation questions before ordering.

  1. Measure both sidesSend the OD/ID and material of the larger and smaller microduct.
  2. Identify the transitionState whether the joint is DB-to-DI, house entry, chamber or another route point.
  3. Match the FPG codeRequest the correct reducer code and tapered-hole dimensions from the published table.
  4. Confirm the testsShare pressure, leak, pull and cable-blowing requirements plus current document needs.

FAQ

Frequently asked questions

What is a microduct reducer coupler used for?

It connects two compatible microducts with different outside diameters, often at a route transition.

Can it connect DB and DI microducts?

The source describes DB-to-DI transition use, such as entering a house. Confirm both tube specifications for the selected FPG code.

How do I select an FPG reducer size?

Provide OD/ID and material for both ducts and request the matching FPG code and tapered-hole dimensions.

What pressure data is published?

The source states 0–1.6 MPa operating pressure and 2.5 MPa proof pressure. Confirm the test method and project safety margin.

Does the reducer have outdoor protection?

IP68 is stated on the source page. Confirm environmental exposure and current model evidence before specification.

What should a reducer-coupler quotation include?

Send both duct dimensions, transition location, route conditions, tests, quantity, packing and drawing or compliance requirements.
