The STORM 15013 is a stainless steel bleed screw with an O-ring, designed for use with brass valve bodies. Bleed screws serve as manual vent points that allow trapped air or pressure to be relieved from a valve or line without fully disassembling the system. The stainless steel construction provides corrosion resistance in wet service environments, and the included O-ring ensures a leak-free seal when the screw is reseated after venting. This component is typically installed by licensed plumbers or HVAC technicians during system commissioning or maintenance.
The 15013 is suited for use in residential and light commercial plumbing and hydronic heating systems where brass valves are present. It is a common service part used during air purging of hydronic loops, pressure relief testing, and routine valve maintenance. Because it is compatible with all brass valve configurations per the manufacturer designation, it serves as a practical replacement or spare for service vans and shop inventory.
Designed as a replacement bleed screw for all brass valve bodies as specified by the manufacturer. Consult the original valve documentation to confirm thread size and O-ring dimensions before installation.
Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and relieve any residual line pressure before removing the existing bleed screw. Inspect the valve seat for damage or debris before threading in the replacement screw, and ensure the O-ring is properly seated to prevent leaks upon restart.
