Yellow Jacket 19011 – 3/8" Quick Coupler Hose Gaskets, 10-Pack

The Yellow Jacket 19011 gasket set includes ten replacement rubber gaskets designed for 3/8" quick coupler hose ends used in HVAC/R charging and recovery applications. These gaskets are engineered to maintain a tight seal under high-pressure refrigerant flow and to resist degradation caused by system oils, moisture, and thermal cycling.

Product Features

• Application: Designed specifically for 3/8" quick coupler hose fittings
• Material: High-grade rubber compound provides compression set resistance and extended service life
• Function: Maintains a pressure-tight seal to help prevent refrigerant leaks during charging, evacuation, or recovery operations
