Connection Configuration:

The T-style design allows you to connect multiple hoses or gauges simultaneously whilst maintaining a secure connection to your vacuum pump or system. The adapter screws onto any standard 1/4" flare fitting and provides both 1/4" flare and 1/2" ACME connections, giving you maximum flexibility in your HVAC/R service work.

Applications:

• Vacuum pump to manifold gauge connections
• HVAC/R system evacuation
• Refrigeration service and maintenance
• Air conditioning installation and repair
• Connecting multiple hoses to single port
• Mini-split system evacuation
• Commercial refrigeration service

Swivel Advantage:

The swivel action on both connection points prevents hoses from twisting and kinking during evacuation procedures. This ensures consistent vacuum flow, reduces wear on hoses, and makes it easier to position equipment in tight spaces. The swivel mechanism maintains a leak-free seal whilst allowing free rotation.

Why Use a T-Style Adapter?

• Versatility – Connect different hose types simultaneously
• Efficiency – No need to disconnect and reconnect different hoses
• Compatibility – Works with both 1/4" FL and 1/2" ACME fittings
• Professional Setup – Enables proper manifold and vacuum pump configurations
• Time Saving – Quick connections without adapting between jobs

Installation:

Thread the adapter onto your existing 1/4" flare fitting, ensuring threads are clean and free from debris. Tighten securely but do not over-tighten. Connect your 1/4" flare hose to one port and your 1/2" ACME hose to the other. The swivel action allows hoses to rotate freely whilst maintaining leak-free seals.

Maintenance:

Keep threads clean and free from refrigerant oil buildup. Inspect O-rings and sealing surfaces regularly for wear or damage. Replace if leaks develop. Store in a clean, dry location to prevent contamination and corrosion.
