long term Electrical AC Whip Assembly -1/2" x 4ft Non-Metallic Liquid Tight Electrical Conduit and 10 Gauge Wire A/C Hook-up Whip Kit

Why this whip earned a spot in my HVAC kit

A good A/C hook-up whip should disappear after the install—quietly doing its job without leaks, kinks, or callbacks. That’s been my experience with this nonmetallic, liquid-tight 1/2-inch, 4-foot whip with preinstalled #10 THHN conductors. I’ve used it on small condensers and mini-split outdoor units where a short, flexible connection from the disconnect to the equipment makes all the difference. It’s straightforward, code-friendly, and it trims real time off a job.

What’s in the kit

• 4 feet of liquid-tight flexible nonmetallic conduit (LFNC-B), 1/2-inch trade size
• Three #10 THHN conductors with distinct color coding
• One straight and one 90-degree nonmetallic connector
• Pre-stripped leads trimmed for termination
• UL listing and UV-resistant Type B conduit rated 80°C dry, 60°C wet, 70°C oil

There’s nothing exotic here—just the right pieces, ready to go. The connectors are the typical nonmetallic liquid-tight style, and the fittings seated well on standard knockouts.

Build quality and materials

The conduit is the star. It’s flexible without collapsing, and it holds its shape when you route around tight corners or set a gentle bend toward a knockout. I’d place the stiffness right in the sweet spot: not so floppy that it sags, but not a wrestling match either. The jacket feels dense and consistent, with clean cut ends and no burrs inside to scrape conductors.

The Type B LFNC rating matters outdoors. Between UV resistance and those temperature ratings (80°C dry, 60°C wet, 70°C oil), it’s built for the condenser pad, pool equipment pad, or a spa equipment bay. I also appreciate that the conduit jacket didn’t chalk up or get brittle after sitting in direct sun for a few weeks before install—an easy way to spot cheaper formulations.

The THHN conductors are standard fare, with clear, durable print and proper strip lengths out of the box. Insulation nicks are a non-issue when the ends are prepped correctly, and that’s the case here. Color coding is obvious and saves you from second-guessing once you’ve got your hands inside a tight disconnect enclosure.

Installation experience

I used this whip on a 12,000 BTU mini-split condenser and on a small conventional condenser with a 25A MOCP. Both installs went smoothly.

Highlights:
- The pre-stripped leads were trimmed to a practical length—long enough to land in a disconnect and swing into a condenser’s service compartment without splices, but not so long that you’re stuffing excess wire into the can.
- Having both straight and 90-degree connectors is genuinely useful. In one install the straight fitting hit the sweet spot from the disconnect, while the 90 got me a clean drip loop into the condenser.
- The locknuts seated squarely, and the connectors’ gaskets compressed evenly. I give nonmetallic fittings a quarter-turn past hand-tight and check for wobble; these stayed put.
- The 1/2-inch trade size matched the knockouts on the equipment and disconnect. No bushings or step adapters were needed.

If you’re used to assembling whips from scratch—cutting conduit, fishing conductors, gluing PVC, and sourcing fittings—you’ll notice the time savings. On a routine condenser swap, I’d estimate this kit trims 20–30 minutes, especially if you account for fewer trips back to the truck.

Compatibility and sizing

With #10 THHN conductors, the whip is best suited for circuits up to 30A (check your equipment nameplate and the 75°C lug rating on the equipment). That puts it in the comfort zone for many mini-splits in the 9,000–12,000 BTU range and a chunk of smaller condensing units, plus outdoor pumps and similar loads. If you’re connecting a larger 4–5 ton condenser with a 40A or higher MOCP, you’ll need a heavier-gauge whip.

The 4-foot length covers typical distances from disconnect to condenser without droop. If your disconnect lands behind the unit or you’re navigating around a vertical gas riser, measure the run; 4 feet can be tight if you need a generous service loop or a long drip.

Where it fits

I’ve found it ideal for:
- Small split condensers and mini-splits (outdoor units)
- Pool and spa pumps/controllers
- Outdoor lighting power drops from a weatherproof box
- Small motors and control boxes on exterior walls
- Short exterior runs where flexibility and a liquid-tight seal are key

It’s also a clean replacement when you’re removing a cracked metallic whip. Because the conduit is nonmetallic, you’re not relying on the conduit as an equipment grounding path; the included green conductor handles grounding.

What it’s not

• Not a long-run solution. Four feet is meant to bridge from disconnect to equipment—not to substitute for conduit runs back to a panel.
• Not for high-amperage HVAC equipment that calls for #8 or larger conductors.
• Not a bonding path. Nonmetallic conduit and fittings don’t provide equipment grounding continuity; you must land the green conductor properly on both ends.

Safety and code notes

• UL listing and the LFNC-B rating tick the compliance boxes I’m looking for outdoors. Always verify your local code preferences, but this style of whip is standard practice in residential and light commercial HVAC.
• Check your conductor sizing against the equipment nameplate (MCA/MOCP) and termination temperature ratings. #10 THHN is commonly good for 30A circuits under 75°C terminations, which is where most HVAC gear lives.
• Make a drip loop into the unit and keep the connectors oriented so the seal doesn’t collect water. It’s easy to get lazy on the last 10 minutes of an install—don’t.
• Tug-test your terminations and torque to manufacturer specs. The pre-stripped ends invite speed; still take the time to torque properly.

Value

The value proposition is simple: it saves time without sacrificing quality. Buying conduit, fittings, and wire separately can be economical in bulk, but for one-off installs or service calls, the convenience more than makes up the price difference. The included 90-degree connector is a small but meaningful add; those are too often missing from cheaper kits, and it keeps your finished run tidy.

Longevity matters, and while I can’t fast-forward a few years, the material quality inspires confidence. I’ve had no issues with connector creep, jacket cracking, or moisture intrusion during commissioning and follow-up visits.

Alternatives and considerations

• Need more length? Look for a 6-foot variant, but mind voltage drop and cable management if you introduce big service loops.
• Need more ampacity? Choose a whip with #8 conductors and confirm the fittings and conduit trade size match your knockouts.
• Prefer metallic? Armor whips are fine, but they’re heavier, harder to shape neatly in tight spaces, and don’t buy you much if the equipment already requires a dedicated grounding conductor.

The bottom line

This AC whip checks the boxes I care about: flexible LFNC-B conduit that behaves well during routing, #10 THHN conductors with clean prep, and both straight and 90-degree fittings that actually seal. It simplifies a common task, keeps installs tidy, and holds up outdoors. The limitations are clear—4 feet of reach and 30A-class conductors—but those are reasonable constraints for its intended use.

Recommendation: I recommend this whip for small-to-medium HVAC and outdoor equipment hookups where a 1/2-inch, 4-foot, #10 THHN solution is appropriate. It’s a time saver with solid build quality, and it delivers a clean, code-compliant connection without fuss. If your application demands longer runs or higher ampacity, step up to a longer or heavier-gauge kit; otherwise, this one belongs in your standard install kit.
