S1 Coupling Kit – 3/4" & 3/8" Refrigerant Line Connectors (2-Pack)

The S1 Coupling Kit includes two precision-engineered fittings—one 3/4" and one 3/8"—designed for clean, secure connection of refrigerant lines and valves in your S1 split-system air conditioner installation.

These couplings are made to fit Nomadic S1 AC units and provide a reliable interface for both the high-pressure and low-pressure lines, ensuring consistent refrigerant flow and minimizing risk of leaks.

Kit includes: (1) 3/4" coupling and (1) 3/8" coupling.

Features & Benefits

  • Precision-Machined Fit: Designed specifically for S1 refrigerant line specifications.
  • Two Sizes Included: One 3/4" coupling for high-pressure, one 3/8" for low-pressure lines.
  • Leak-Resistant Design: Threaded ends ensure tight seals when properly torqued.
  • Durable Construction: Built from corrosion-resistant metals for long service life.
  • Essential Installation Component: Required to connect refrigerant lines during S1 AC setup.

Frequently Asked Questions

Q: Are these the couplings I need to install the S1 AC unit?
A: Yes. These two couplings—one 3/4" and one 3/8"—are required for connecting the refrigerant lines between the indoor and outdoor units.

Q: Are the couplings included with the S1 AC unit?
A: No. This coupling kit is sold separately and is required for first-time installations or replacements.

Q: What tools do I need to install these?
A: A torque wrench and compatible flaring or compression tools may be required, depending on your specific installation method and system pressure.
