Dura-line 20005735 Straight Coupler 16mm 13mm

Product Description

The DURA-LINE 20005735 is a straight coupler designed to join conduit sections in microduct and innerduct installations. It provides a secure, in-line connection between 16mm and 13mm conduit segments, maintaining a clean pathway for fiber optic cable, low-voltage wiring, or communication lines. This fitting is sold individually and is intended for installation by telecommunications contractors, electrical contractors, and data network technicians working with modular conduit systems. The straight coupler design eliminates the need for adhesive or additional fittings at standard in-line joints.

This coupler is suited for use in underground, direct-buried, or enclosed conduit runs where microduct or innerduct systems require segment-to-segment connections. It is commonly used in fiber optic network builds, campus cabling infrastructure, and utility corridor installations. The 16mm to 13mm sizing makes it appropriate for transitional or reducer-style in-line connections within modular conduit assemblies. Each unit is sold as a single piece.

Key Features

• Straight in-line coupler design for clean, secure conduit-to-conduit connections
• Fits 16mm and 13mm conduit segments for transitional or matched joining
• Modular connector style compatible with microduct and innerduct systems
• Single-unit packaging allows for precise quantity purchasing
• No adhesive required for standard in-line joint assembly

Compatibility

Designed as an OEM-style replacement and standard fitting for modular microduct and innerduct conduit systems requiring 16mm and 13mm straight in-line connections.

Installation Notes

Installation is typically performed by telecommunications or low-voltage electrical contractors following applicable NEC and local conduit installation codes. Ensure conduit ends are clean, deburred, and free of debris before seating the coupler. Verify conduit diameter sizing matches the fitting before installation to prevent improper seating or pathway compromise. Do not overtighten or force the fitting onto mismatched conduit sizes.
