Brass R410A AC Adapter Fitting - 1/4' Male To 5/16' Female For Mini Split Systems

About This Product

HVAC technicians and DIYers working on mini split systems, this brass adapter is one of those specialized tools that makes your life so much easier. It converts from 1/4 inch male SAE to 5/16 inch female SAE, which is exactly what you need for connecting standard charging hoses to many imported R410 mini split systems. The brass construction is durable and resists corrosion, which is crucial when you're dealing with refrigerant systems. The anti-backflow design prevents refrigerant loss and maintains system integrity during charging or vacuuming operations. Installation is straightforward - the SAE female nut with pressure drop connector makes it simple to attach to your mini split unit without any modifications. This is specifically designed for R410 refrigerant on the low pressure side, so make sure you're using it for the correct application. The gold-colored brass looks professional and the overall build quality feels solid, not cheap like some import adapters. Having this in your tool bag means you can service a wider range of mini split systems without needing multiple specialized hoses. Whether you're a professional HVAC technician adding to your service kit or a knowledgeable homeowner maintaining your own system, this adapter solves that common compatibility issue between standard tools and specific mini split fittings. Just remember to always follow proper safety procedures when working with refrigerant systems.
