The YELLOW JACKET 41095 is a sight glass tool designed for refrigeration and air conditioning service work. Known in the field as the Ritchie Sight Glass Tool, it allows HVAC technicians to properly install, remove, or service sight glass fittings in refrigerant lines. Sight glasses are critical diagnostic components that let technicians observe refrigerant flow and moisture indicator color changes without opening the system. The 41095 provides the mechanical leverage and fit needed to work with these fittings cleanly and without damage to the sight glass or surrounding line components.
This tool is intended for use by licensed HVAC and refrigeration technicians during system installation, commissioning, and service calls. It is applicable to both residential and light commercial refrigerant line applications where sight glasses are present. The Ritchie Sight Glass Tool name is associated with professional-grade refrigeration service tooling, making the 41095 a recognized choice among refrigeration service professionals who work with a range of system configurations.
Designed for use with sight glass fittings found in refrigeration and air conditioning refrigerant line sets, consistent with standard HVAC and refrigeration service applications.
Installation and removal of sight glasses should be performed by a licensed HVAC or refrigeration technician. Before servicing any sight glass fitting, recover refrigerant and relieve system pressure in accordance with EPA Section 608 requirements and applicable local codes. Avoid over-torquing sight glass fittings, as the glass element is fragile and can crack under excessive force. Inspect threads and sealing surfaces before reinstalling any sight glass component.
