Yellow Jacket 19090 1/4 Inch Flare Snap-it Coupler

Product Description

The YELLOW JACKET 19090 is a 1/4-inch flare Snap-It coupler designed for quick, secure connections on refrigerant lines and manifold gauge hose assemblies. This coupler uses the standard 1/4-inch flare fitting size common throughout HVAC refrigerant service work. It is built for use by licensed HVAC technicians during system charging, recovery, and evacuation procedures. The snap-style engagement mechanism allows faster hose connections compared to threaded couplers, reducing connection time on the job. The coupler is yellow in color, consistent with standard HVAC service hose and fitting color conventions.

This coupler is intended for use in commercial and residential HVAC refrigerant service applications. It connects to 1/4-inch flare fittings found on manifold gauge sets, vacuum pumps, refrigerant recovery machines, and service ports. HVAC technicians use snap-it style couplers when frequent connect-and-disconnect cycles are required during system diagnostics and refrigerant handling. It is suited for use in both field service and shop environments.

Key Features

• 1/4-inch flare connection size for compatibility with standard HVAC service equipment
• Snap-It design enables quick connect and disconnect without full thread engagement
• Yellow color for easy identification in a multi-hose service setup
• Compact coupler form factor for use in tight equipment access areas

Compatibility

Designed as a standard 1/4-inch flare service coupler for use with HVAC manifold gauge sets, refrigerant hoses, and service equipment that accept 1/4-inch flare fittings.

Installation Notes

Installation and use of this coupler should be performed by a licensed HVAC technician familiar with refrigerant handling regulations under EPA Section 608. Always recover refrigerant and relieve system pressure before disconnecting service hoses or couplers. Inspect the coupler seating surface and O-ring condition before each use to prevent refrigerant leaks at the connection point. Do not overtighten or force the snap mechanism if resistance is felt, as this may indicate misalignment with the fitting.
