100FT Liquid-Tight Conduit And Connector Kit
Product overview: 100 ft of flexible, non-metallic liquid-tight conduit with a 0.63 inch inner diameter and 0.83 inch outer diameter. Includes five straight and three 90-degree fittings. Made from corrosion-resistant PVC with a smooth interior for easier wire pulling. Thick 2.5 mm wall offers enhanced tensile and compressive strength. Suitable for outdoor, UV-resistant, and direct burial applications.
- Best for outdoor lighting, security systems, and long runs where moisture, oil, and abrasions are a concern.
- Limitations: Not metal; may not provide magnetic shielding or electrical durability in extremely high-temperature environments beyond PVC capabilities.
CrocSee 25ft Split Wire Loom Tube
Product overview: A 25 ft length of 1/2 inch split wire loom built from flame-retardant polypropylene. Includes a wire loom insertion tool for easier threading. Operating temperature range from -22 °F to 221 °F. Ideal for automotive, industrial, office, and home wiring protection.
- Best for quick wire management in tight spaces where split protection helps organize multiple cables.
- Limitation: May be shorter for long runs; buy additional length for larger projects.
Electrical Conduit Kit 3/4” 4FT
Product overview: Non-metallic PVC liquid-tight conduit kit. Includes a 4 ft gray PVC conduit along with a straight and a 90-degree connector. Designed to be flexible and corrosion-resistant, suitable for tight spaces and harsh environments where non-metallic protection is preferred.
- Best for small-space conduit runs where metallic options are impractical.
- Limitation: Limited length per kit; may require extensions for longer installations.
Liquid-Tight Conduit Kit 1/2 Inch 25 Ft
Product overview: 1/2 inch flexible conduit with a 25 ft length. Includes five straight and three 90-degree fittings, with a smooth interior for easier wire pulling. The conduit is described as corrosion, water, oil, abrasion, acid, and shavings resistant, suitable for direct burial and outdoor use with continued flexibility in extreme temperatures.
- Best for outdoor and industrial environments where long runs and robust fittings are needed.
- Limitation: PVC flexibility can degrade under extreme UV exposure without proper protection.
Wire Loom 1/2 Inch 10ft
Product overview: 10 ft length of split loom tubing in 1/2 inch diameter made from PE. Designed for easy insertion with a split design, offering protection in automotive, home, and office wiring applications. Operating range from -40 to 257°F (-40 to 125°C) with good chemical resistance to gasoline and oils.
- Best for automotive and small-to-medium wiring protection where quick access and maintenance are needed.
- Limitation: Shorter length may require joining or multiple pieces for larger projects.
Buying Guide
What to consider when selecting explosion-proof and flexible conduit:
- Environment and exposure: Choose PVC-based liquid-tight conduits for outdoor use and direct burial; metal conduits offer higher mechanical protection where lightning or strong impacts are concerns.
- Conduit size and length: Measure the required run length and diameter. Longer runs reduce the need for many fittings; ensure the inner diameter is sufficient for the wires being pulled.
- Chemical and temperature resistance: For oily, acidic, or chemical-rich environments, select conduits with proven chemical resistance and a tolerance to temperature swings.
- Flexibility vs. rigidity: In tight spaces, split loom and flexible LC conduits are easier to route. For exposed outdoor locations, rugged, thicker-walled conduits add durability.
- Installation accessories: Look for included fittings (straight and 90-degree) to ensure waterproof joints and easier installation.
- Direct burial readiness: If burying conduits, confirm suitability for direct burial and UV resistance where applicable.
Practical Tips For Buyers
- Plan runs with spare fittings to accommodate future changes.
- Check for compatibility with existing connectors and boxes before purchase.
- Prefer split loom for simple rework or upgrades to existing harnesses.
Frequently Asked Questions
- What is explosion-proof conduit?
Answer: Explosion-proof conduits are designed to resist harsh environments and prevent ignition in flammable atmospheres, while providing electrical protection and weather resistance. They may be non-metallic or metal-based depending on application needs. - Can I bury liquid-tight conduits directly in soil?
Answer: Yes, many are suitable for direct burial, but confirm the product’s UV resistance and suitability for burial in your region. - What size conduit should I choose for a given wire bundle?
Answer: Select a conduit with an inner diameter ample enough to pull wires without bending or rubbing. Overloading can cause insulation damage during installation. - Are split loom protectors heat resistant?
Answer: Split loom protectors are designed for moderate heat exposure; verify the operating temperature range to ensure compatibility with your environment. - What fittings are typically included in these kits?
Answer: Most kits include straight and 90-degree fittings, enabling waterproof joints and adaptable routing for complex runs. - Is PVC better than metal for outdoor conduit?
Answer: PVC is corrosion-resistant and lighter, making it easier to install; metal conduits offer higher physical protection in certain harsh environments. Choose based on project demands.
