Answer:
When installing a Senville mini-split, it’s important to follow the correct torque specifications for the refrigerant line connections to ensure a proper seal and avoid leaks. In our experience, using a torque wrench is essential to achieve the manufacturer-recommended tightness. The typical torque specs for Senville mini-splits using R-410A refrigerant are as follows:
- 1/4-inch line: 10-13 ft-lbs (13.6-17.6 Nm)
- 3/8-inch line: 24-30 ft-lbs (32.5-40.7 Nm)
- 1/2-inch line: 36-42 ft-lbs (48.8-56.9 Nm)
- 5/8-inch line: 50-62 ft-lbs (67.8-84.1 Nm)
Always double-check your model’s manual for specific values and ensure connections are properly aligned before tightening.

Using the correct torque specifications during installation is critical for the performance and longevity of your mini-split system. Over-tightening the flare nuts can crack or damage the fittings, leading to refrigerant leaks, while under-tightening may cause the same problem by failing to seal the connection. In our experience, flare connections are one of the most sensitive parts of the installation process, and mistakes can be costly.
We always recommend investing in a quality torque wrench calibrated for HVAC work. Ensure the connections are clean and burr-free before tightening, as imperfections can also lead to leaks. Additionally, applying a small amount of refrigerant oil to the flare fittings before tightening can help create a better seal. If you’re unsure or don’t have the right tools, it’s always best to leave the job to a certified HVAC technician, as they have the expertise to ensure everything is installed correctly and safely.
