发明名称 Valve stem extension
摘要 A valve stem extension for extending the length of a valve stem, the valve stem extension including an extension member and a rotation resisting member. The extension member has a first end for engaging the valve stem and defines an opening which exposes two opposing flat sides of the valve stem when the extension member is engaged with the valve stem. The rotation resisting member includes two opposing flat sides and is configured to be insertable within the opening of the extension member after engagement of the extension member with the valve stem. When positioned in the opening of the extension member, the two opposing flat sides of the rotation resisting member engage the two opposing flat sides of the valve stem to resist rotation of the extension member relative to the valve stem.
