1/4" Quick SealRight Coupler

Yellow Jacket 19109 SealRight 1/4" Straight Quick Coupler

The Yellow Jacket 19109 SealRight Coupler is designed to provide secure, leak-minimizing connections for high-pressure HVAC and refrigeration service. Featuring a straight, in-line configuration and a one-piece construction, this coupler enables faster attachment to standard 1/4" access ports while helping to limit refrigerant discharge during hose removal.

Key Features

• Automatic Shut-Off: Traps refrigerant in the hose to minimize venting when the coupler is disconnected.
• One-Piece Design: Simplifies connection and disconnection, reducing attachment time compared to two-piece assemblies.
• Burn Protection: Internal design helps reduce contact with hot pressurized components during disconnection.
• High-Pressure Rated: Suitable for applications up to 800 psi working pressure and 4000 psi burst pressure.
• Refrigerant Compatibility: Works with common refrigerants including R-12 and R-134a.

Technical Specifications

• Connection Size: 1/4" male flare x 1/4" female flare
• Design Angle: 0° (straight)
• Maximum Working Pressure: 800 psi
• Burst Pressure: 4000 psi
• Construction: One-piece, machined metal body with integrated shut-off valve

Application and Installation Notes

For optimal performance and regulatory compliance, installation of the SealRight coupler should be performed by qualified HVAC technicians. This coupler is intended for use with compatible refrigerant charging hoses and standard service ports. Always depressurize the system and follow applicable safety protocols before connecting or disconnecting service tools.

Contractor Considerations

• Time Savings: Single-body design streamlines hose attachment and reduces handling time in field applications.
• System Protection: Limits refrigerant release at disconnection to support EPA Section 608 compliance efforts.
• Service Port Integrity: Provides a consistent seal and reliable engagement under pressure.
