Reinforced Non-Metallic Conduit Construction
The conduit combines a flexible thermoplastic body with an embedded reinforcing member inside the conduit wall.
This construction provides mechanical support while allowing the conduit to follow equipment connections and wiring routes where rigid conduit may be less convenient.
The smooth inner surface helps cables pass through the conduit, while the corrugated outer profile provides flexibility for routing around equipment and installation obstacles.
Liquid-Tight Protection with Compatible Fittings
The conduit is intended to work together with compatible liquid-tight fittings as part of the electrical wiring system.
The current product information states that improved water protection for the complete wiring system is achieved when the conduit is correctly connected with the appropriate liquid-tight fitting.
Actual environmental protection depends on the conduit, fitting, enclosure, installation method and the requirements of the electrical system. Buyers should confirm the required fitting type and applicable electrical code before installation.
Nylon Liquid-Tight Connectors
DABUND also supplies liquid-tight connectors for use with compatible non-metallic conduit.
According to the current product information, the connectors are made from nylon and are designed for resistance to salt water, weak acids, alcohol, oil, grease and common solvents.
The conduit size, connector size, enclosure entry and thread configuration should be confirmed before ordering to ensure that the components match the intended wiring system.
Why Use Non-Metallic Liquid-Tight Conduit?
Flexible Wiring Protection
Flexible conduit can simplify wiring routes around HVAC equipment, motors and other installations where rigid raceway routing may be difficult.
Smooth Interior for Cable Routing
The smooth inner surface helps reduce obstruction when electrical conductors or cables are routed through the conduit.
Reinforced Wall Construction
The embedded reinforcing member provides additional support and helps improve resistance to crushing during normal installation and service conditions.
Lightweight Non-Metallic Design
The non-metallic thermoplastic construction provides a lightweight conduit option for compatible electrical wiring applications.
Applications
Non-metallic liquid-tight conduit can be considered for compatible electrical wiring and equipment connections in applications including:
Air-conditioning outdoor unit connections
Ductless mini split systems
Heat-pump equipment
Motors and control equipment
Outdoor lighting systems
Pool and spa equipment where permitted by applicable electrical requirements
Solar equipment wiring
Generator equipment
Short-run exterior electrical connections
General electrical cable and wire protection
The current product information also references use with some 9,000–12,000 BTU mini split installations. Conduit selection, however, should be based on the electrical wiring requirements, cable size, conduit size, fittings and applicable electrical code rather than BTU capacity alone.
How to Select Non-Metallic Liquid-Tight Conduit
Confirm the Required Conduit Size
Determine the conduit size required for the conductors or cable being installed. Consider conductor quantity, cable dimensions and the applicable electrical installation requirements.
Confirm the Matching Connector Size
The liquid-tight fitting must match the conduit and the equipment enclosure or junction box connection.
Check the Installation Environment
Confirm whether the conduit will be installed indoors, outdoors or in an area exposed to moisture, oil, sunlight or other environmental conditions.
Check Flexibility and Routing Requirements
Plan the conduit route and allow suitable space for bends and equipment movement without excessively bending, crushing or twisting the conduit.
Confirm Applicable Electrical Requirements
Buyers and installers should confirm the applicable electrical code, project specification and required product documentation before selecting the conduit for a particular installation.
How to Install Liquid-Tight Conduit
Step 1: Plan the Wiring Route
Determine the route between the electrical enclosure and the connected equipment before cutting or installing the conduit.
Step 2: Select the Correct Conduit and Fittings
Confirm that the conduit, fittings and enclosure entries are compatible in size and configuration.
Step 3: Cut the Conduit Cleanly
Prepare a clean conduit end according to the fitting installation method and remove material that could interfere with cable routing or fitting engagement.
Step 4: Route the Electrical Cable
Route the required conductors through the conduit while avoiding excessive pulling force, sharp bends or conduit damage.
Step 5: Install the Liquid-Tight Fittings
Assemble the compatible fittings according to the fitting manufacturer's installation method and ensure that the conduit is properly seated.
Step 6: Inspect the Completed Connection
Check the conduit routing, fitting engagement and enclosure connections before the electrical system is placed into service.

Non-Metallic Conduit for HVAC Installations
HVAC outdoor units, mini split systems and heat pumps frequently require a protected electrical connection between equipment and the disconnect, junction box or other electrical enclosure.
Flexible non-metallic conduit can simplify short equipment connections where the selected conduit and fittings meet the electrical and environmental requirements of the installation.
Conduit selection should be based on electrical requirements rather than air-conditioning capacity alone.
