Stop Sourcing Parts From Five Different Places

When you're installing a mini-split on your off-grid build, the last thing you need is a third trip to the hardware store because the communication wire doesn't match or the wall sleeve is the wrong size. The EZFlex™ Full Installation Kit eliminates that guesswork entirely. Every component in this bundle is pre-selected to work together — the lineset diameter, the wire gauge, the sleeve dimensions, the drain hose fit. We already did the compatibility work so you don't have to. Pick your length and diameter, and the rest is handled.

Flexible Stainless Steel That Handles Real Routing

Flexible Stainless Steel That Handles Real Routing

The core of this kit is the EZFlex™ flexible insulated lineset — stainless steel construction that bends around obstacles without kinking or compromising refrigerant flow. Available in four diameter combinations and three lengths (10, 16, or 25 feet), it covers the configurations most mini-split systems require. The insulation is field-tested for temperature stability, so it holds up through summer heat and winter cold without degrading. This isn't a rigid copper run that forces your routing decisions — it adapts to your build, not the other way around.

Professional Wall Penetration Without the Callbacks

Professional Wall Penetration Without the Callbacks

A mini-split install is only as good as the wall pass-through. This kit includes a super-tough wall sleeve and cap set for a clean, reinforced penetration point, plus two packs of wall-sealing putty for an airtight, pest-proof closure that keeps bugs and conditioned air where they belong. The reinforced 5/8" OD drain hose handles condensate runoff without collapsing. The 4-lead communication wire comes with pre-crimped terminal spade ends — no stripping, no crimping, no guessing which wire goes where. Everything is built to get the job done right the first time.

Compatibility Check

Verify these conditions before ordering to ensure a proper fit.

  • Mini-split unit requires a 1/4" liquid line
  • Wall penetration distance matches 10', 16', or 25' lineset
  • Suction line diameter matches your unit spec (3/8", 1/2", or 5/8")

“Installed a Pioneer mini-split on my 800 sq ft off-grid cabin last month. This kit had everything — lineset, wire, wall sleeve, putty, drain hose. No trips to town, no mismatched fittings. The flexible lineset made routing through my stud wall straightforward. Done in about three hours.”

Frequently Asked Questions

When you source a flexible lineset, communication wire, wall sleeve, sealing putty, and drain hose individually, you're paying separate shipping charges and spending time verifying that each part actually fits. The EZFlex™ kit rolls every component into one package at $127.95 with free shipping. You're paying for the parts — the coordination and compatibility are included at no extra cost.
Big-box stores sell individual HVAC parts off a shelf with no guidance on which diameter or length matches your specific mini-split unit. Off Grid Vault curates complete kits where every component is pre-selected to work together. If something doesn't fit your application, you have a real point of contact — not a return counter. We stand behind what we sell with a 30-day performance guarantee.
Check your mini-split unit's specification sheet for the required liquid and suction line sizes — that determines your diameter. Measure the distance between your indoor and outdoor units along your planned routing path to determine length. If you're unsure, take advantage of our free system design consultation. Tell us your mini-split model and your install layout, and we'll confirm the exact kit configuration you need.
The EZFlex™ flexible lineset uses stainless steel construction designed for real-world installation conditions. It bends around structural obstacles without kinking, which rigid copper cannot do without specialized tools and brazing. The insulation layer provides temperature stability across seasonal extremes. For off-grid and remote installations where professional brazing equipment may not be available, the flexible design delivers a reliable, field-tested connection that holds up.
The EZFlex™ kit is designed around standard mini-split lineset diameter configurations — the same sizes used across most major mini-split manufacturers. The communication wire uses a standard 4-lead configuration with pre-crimped spade terminals that match common wiring setups. That said, always verify your specific unit's line size requirements before ordering. If you need help matching components, our free consultation covers exactly this.
For a straightforward wall-through installation on a single-zone mini-split, most experienced installers complete the job in two to four hours. The pre-crimped communication wire and included wall sleeve eliminate the most time-consuming preparation steps. If you're a first-time installer, plan for a half day — the kit removes the parts-sourcing delays, so your time goes entirely into the physical install.
