HydroMaxx 3/8″ Flexible Non Metallic UL Liquid Tight Conduit
The HydroMaxx 3/8″ flexible, non-metallic liquid-tight conduit is designed for extremely tight installations. Its flexible construction helps reduce bending stress and wire pulling in cramped spaces. Being non-metallic, it is lightweight, which can lower overall installed costs and minimize labor effort during routing and termination. The conduit resists moisture intrusion and is suited for indoor use in damp locations, making it a practical choice for basements, crawl spaces, and outdoor enclosures when protected from direct exposure.
Key features include: non-metallic material for easy handling, flexibility for tight quarters, and a focus on lightweight installation. Consider compatibility with compatible fittings and seals to maintain a watertight assembly in areas subject to splash or moisture exposure. This option pairs well with nylon fittings designed for rugged environments where chemical resistance is important.
ULTRA FLEX PVC 3/8″ Liquid Tight Conduit (100 Ft)
The Flexible PVC non-metallic liquid-tight conduit from ULTRA FLEX PVC PIPE provides a robust option for environments with exposure to oil, water, and potential chemical contact. It combines UL-rated performance with a lightweight design that eases installation, especially in cramped spaces where traditional rigid conduits are impractical. The smooth interior helps reduce friction during wire pulling, contributing to faster and cleaner terminations in both indoor and outdoor applications where a weather-resistant seal is needed.
The conduit is designed to resist corrosion and environmental wear while remaining flexible enough to adapt to complex routing. It pairs effectively with corresponding liquid-tight fittings and gaskets to ensure a reliable, leak-resistant assembly over long runs, including outdoor installations where UV stability is a factor.
Hydromaxx 4 Pack: Non Metallic Liquid Tight Conduit Fittings
This 4-pack includes 2 straight fittings and 2 angle fittings, all nylon construction with strong resistance to saltwater, weak acids, gasoline, and common solvents. Nylon 6 provides a balance of durability and temperature tolerance, while the sealed design aids quick, tool-free installations. The domed sealing nut and locknut system streamline securing the conduit to chassis openings or NPT-threaded holes, contributing to a reliable seal in compact assemblies.
Ideal for installations requiring quick assembly and durable performance in marine or industrial settings. The included fittings help maintain proper conduit alignment and leak resistance without disassembly, supporting efficient field repairs and maintenance where space is limited.
Electriduct 3/8″ PVC Coated Liquid-Tight Galvanized Steel Flexible MCT Conduit (25 Feet)
This conduit blends a galvanized steel core with a liquid PVC coating, delivering enhanced tensile strength and leak-proof performance. The steel core improves durability in high-flex situations and industrial environments, while the PVC coating provides weather resistance and a smoother interior for easier wire pulling. Specifications indicate waterproofing, corrosion resistance, and flame/UV resistance, with a wide operating temperature range compatible with various indoor and outdoor settings.
Ideal for installations where a robust metal core is preferred, yet a flexible, liquid-tight solution is required to accommodate complex routing or movement in machinery, vehicles, or outdoor enclosures. Ensure compatibility with UL-listed fittings to maintain the overall integrity of the system.
uxcell 6Pcs 3/8″ NPT Liquid Tight Connectors, 90 Degree
This 6-pack of 3/8″ NPT liquid-tight connectors provides 90-degree elbow fittings for efficient turns in tight runs. Made from sturdy plastic, they offer waterproofing, corrosion resistance, and reliable sealing with multiple components that contribute to improved leak protection. The connectors are designed to permit a solid grip while allowing for angle routing, which can be essential when wiring around obstacles in compact electrical panels or enclosures.
These connectors are a practical option when you need flexible angles without committing to larger or rigid fittings. Pair them with compatible conduits and gaskets to optimize seal integrity in moisture-prone or dust-prone environments.
uxcell 3Pcs 3/8″ NPT Liquid Tight Connectors, 180 Degree
This set provides three 180-degree liquid-tight connectors in the 3/8″ NPT size, suitable for straight or near-straight conduit runs. The plastic construction emphasizes durability, waterproofing, and resistance to corrosion, with a design that supports secure sealing and resistance to liquid ingress. The 180-degree angle helps accommodate changes in direction without kinking or stressing the conduit.
As with all fittings, match the connector size and thread type to your conduit and enclosure to ensure compatibility and a reliable seal over time in damp or outdoor environments.
Electriduct 3/8″ PVC Coated Liquid-Tight Galvanized Steel MCT – 10 Feet
This 10-foot length offers a shorter alternative to longer runs while maintaining high strength from a galvanized steel core and a liquid PVC coating. The combination yields a durable, flexible conduit that resists water, corrosion, and UV exposure. It is designed for easy wire pulling with a smooth interior and a protective outer coating that helps prevent leaks and abrasion in busy electrical installations.
Consider this option when you need a compact, resilient solution for quick installations or retrofit projects where space is constrained but reliability remains critical.

With an emphasis on ease of use and reliable sealing, this set supports rapid field installations and maintenance tasks, reducing downtime without sacrificing performance in damp or potentially corrosive environments.
Buying Guide: Key Purchase Considerations
- Conduit Material: Non-metallic vs galvanized steel. Non-metallic is lighter and easier to handle in tight spaces, while coated steel provides higher tensile strength for dynamic environments.
- Flexibility vs Rigidity: Flexible conduits simplify routing in cramped areas but ensure compatibility with fittings that maintain a watertight seal.
- Temperature and UV Exposure: Check operating temperature ranges and UV resistance for outdoor or sun-exposed installations.
- Chemical Resistance: If exposure to oils, solvents, or saltwater is expected, choose materials with proven chemical resistance (e.g., nylon, PVC-coated steel).
- Fittings and Accessories: Include compatible elbows, straight fittings, seals, and locking nuts to minimize assembly time and ensure a reliable seal.
- Installation Environment: Indoor vs outdoor, damp locations, and potential vibration or movement—these factors influence material choice and sealing methods.
- Code Compliance: Verify UL ratings and NPT sizing consistency with your electrical panels and enclosures to maintain compliance and safety.
- Cost and Labor: Lightweight, easy-to-install options can reduce labor time; consider total cost of materials plus installation complexity for long runs.
