QILIPSU Waterproof Junction Box IP67 Outdoor Plastic Electri

The Verdict

Let me be straight with you: most “waterproof” junction boxes on Amazon are plastic boxes with a rubber strip and a prayer. The QILIPSU IP67 is not that. This is one of those rare budget components that actually respects its rating.

I’ve installed a dozen of these across outdoor lighting, irrigation controllers, and a pool pump timer setup. Here’s what you need to know before you buy.

What you actually get

The box ships with the enclosure, a pre-installed EPDM gasket, and four Phillips screws. That’s it — no mounting hardware, no cable glands. You’ll want to grab your own. The ABS housing measures roughly 7.5" x 4.3" x 2.8" (the exact dimensions vary slightly by variant), which is enough for a couple of wire nuts, a small relay, or a basic timer module. The lid is opaque on most models, though some variants offer a clear lid option — handy for LED drivers where you want to check status lights.

Real-world performance

The IP67 claim isn’t marketing fluff. I pressure-washed a test unit for two full minutes at close range — water beaded off and the interior stayed bone dry. The gasket channel is deep and the lid compresses evenly across all four corners, which is where cheap boxes usually fail. The ABS material is noticeably thicker than the flimsy polypropylene you find on $8 enclosures; it doesn’t flex when you tighten the screws.

One detail that impressed me: the pre-scored knockouts are actually functional. You can pop out 1/2" and 3/4" conduit entries with a screwdriver, and they break cleanly without cracking the housing. That said, the edges after removal are sharp — run a file over them or use rubber grommets before pulling wire.

What buyers consistently say

Scanning 235 ratings at 4.7 stars, the pattern is clear: people use these for exactly what they should. One reviewer noted, “Used for a well pump control box outside. Survived a Texas summer and a full winter with zero condensation inside.” Another mentioned, “Finally a box where the gasket doesn’t bunch up when you close it.” The handful of negative reviews cluster around two issues: stripped screw holes (usually from over-torquing) and users who expected pre-installed cable glands.

Where it falls short

Let’s be honest about the weak points. The included screws are nothing special — they’ll corrode in coastal salt air within a year. Swap them for stainless #8s, which costs two dollars and saves you a headache. The gasket can shift if you’re careless during assembly; it’s not glued in place, so align it before cinching down. And if you’re running multiple cables, you’ll need to source your own IP67 glands — the knockouts alone don’t seal anything.

Who should buy this

• DIY homeowners wiring outdoor lighting, security cameras, or landscape transformers — this is your box
• Irrigation installers protecting solenoid valves and timer controllers from sprinkler overspray
• Boat/RV owners needing a corrosion-resistant enclosure for 12V accessories (after the screw upgrade)
• Skip it if you need pre-installed glands, DIN rail mounting, or a metal enclosure for heat dissipation — look elsewhere

FAQ

Is this truly IP67 or just “weather-resistant”? Genuinely IP67. I submerged a sealed unit in a bucket for 30 minutes — no water ingress. The gasket does the work, not hope.

Can I mount this directly to wood or concrete? Yes — the back has four external mounting tabs. Use stainless screws for outdoor wood; for concrete, use plastic anchors. The tabs are reinforced, so they won’t snap under normal tension.

Does it fit standard conduit? The knockouts accommodate 1/2" and 3/4" conduit, but you’ll need to buy separate weatherproof connectors. This is a box, not a complete conduit solution.

The Verdict

Buy it if you need a dependable, genuinely waterproof enclosure for outdoor electrical connections without paying Leviton or Hubbell prices. The QILIPSU delivers real IP67 protection, sturdy ABS construction, and enough interior space for most small projects.

Skip it if you expect a plug-and-play solution with glands and hardware included, or if you’re demanding about marine-grade corrosion resistance.

Rating: 4.6/5 — a half-star deduction for the weak included screws and sharp knockout edges. But for the price, this is the best value waterproof junction box I’ve tested in this class. Get the stainless screws, deburr your holes, and it’ll outlast whatever you’re wiring to it.
