This straight adapter converts a one quarter inch SAE hose to a five sixteenth inch SAE service port with a swivel female nut and a built in depressor tip. It is a tidy fix for mixed fittings on R410A and R32 gear and it keeps jobs moving with clean connections, no worries.
Key Features and Trade Benefits
- One quarter to five sixteenth conversion — bridge older hoses to newer minisplit ports in seconds.
- Swivel female with depressor — opens the core for flow and seats neatly for fewer leaks.
- One half twenty UNF thread spec — common service thread for five sixteenth SAE ports.
- Compact and durable — built for daily van use and quick change overs on site.
Why This Product Matters
Real world scenario: in Sydney you arrive to charge a wall split and discover your hose set is one quarter while the service port is five sixteenth. Instead of a dash back to the shop, spin this adapter on, crack the valve, and you are charging in minutes. Fair dinkum time saver. For more fittings, see our HVAC fittings valves and service tools.
Pro Tip
Seat the flare lightly first, then snug to spec to protect the gasket and avoid distortion. Keep a spare gasket kit in the van and replace at the first sign of micro bubbles on a leak test. She will be right when the seal is fresh.
