Yellow Jacket 18996 Shut-off Stem for 19000 Manifold

Product Description

The YELLOW JACKET 18996 is a replacement shut-off stem designed for use with the 19000 series manifold gauge set. The stem controls refrigerant flow at the manifold valve, allowing technicians to open and close the circuit during charging, recovery, or evacuation procedures. It provides a secure seal to prevent refrigerant loss or contamination when connecting or disconnecting hoses and service tools. HVAC/R technicians install this part as a direct replacement when an existing stem is worn, damaged, or leaking past the valve seat.

This shut-off stem is intended for use with the YELLOW JACKET 19000 manifold gauge set in HVAC and refrigeration service applications. It is a service and maintenance part, suited for field repair of the manifold rather than full unit replacement. Typical use cases include repair of manifolds that have developed valve leakage or stem failure after extended field use.

Key Features

• Designed as a direct replacement shut-off stem for the YELLOW JACKET 19000 manifold
• Controls refrigerant flow during charging, recovery, and evacuation operations
• Provides a secure seal to prevent refrigerant loss during hose connection and disconnection
• Allows field repair of the manifold valve without full unit replacement

Compatibility

Designed for use with the YELLOW JACKET 19000 series manifold gauge set.

Installation Notes

Installation should be performed by a licensed HVAC/R technician familiar with refrigerant handling and manifold service procedures. Before replacing the stem, recover all refrigerant from the system or isolate the manifold from the circuit to prevent exposure to refrigerant under pressure. Follow EPA Section 608 requirements for refrigerant handling during service. Use appropriate tools to avoid damaging the valve body threads during stem removal and installation.
