The YELLOW JACKET 18001 is a cylinder gasket designed for use with valve hoses in refrigerant and HVAC service applications. Sold in a 10-pack, this gasket provides a reliable seal at the connection point between refrigerant cylinders and service hoses or manifold valves. Maintaining a proper seal at these connections is critical for preventing refrigerant loss during recovery, charging, and transfer operations. HVAC technicians and refrigeration service professionals install this gasket as a consumable replacement during routine hose and valve maintenance.
This gasket is suited for use in residential and commercial HVAC service work where refrigerant cylinder connections must be leak-free. It is a standard consumable for technicians who regularly connect and disconnect service hoses from refrigerant cylinders. Keeping a supply on hand reduces downtime during service calls where worn or damaged gaskets need immediate replacement.
Designed as an OEM-style replacement gasket for cylinder valve hose connections used in refrigerant service applications.
Installation is performed by qualified HVAC technicians or refrigeration service professionals. Before replacing the gasket, recover any remaining refrigerant pressure from the hose assembly and depressurize the connection point. Inspect the valve seat and hose fitting for damage before seating the new gasket. Follow applicable EPA Section 608 regulations and equipment manufacturer guidelines when working with refrigerant systems.
