The SPECTROLINE GS-1/ECS is a prefilled, disposable fluorescent dye capsule designed for leak detection in air conditioning and refrigeration systems. Each capsule holds 0.5 ounces of fluorescent dye and treats systems with 15.1 ounces to 1.6 quarts of lubricant, 3 to 4.9 pounds of refrigerant, or up to 2-ton cooling capacity. The capsule connects via the low-pressure gauge port of a charged manifold and the system service port, using a bleed valve to inject dye into pressurized systems without the need to recover refrigerant first. HVAC technicians and refrigeration service pros use this capsule as part of a UV leak detection workflow.
This dye capsule is sized for small to medium air conditioning and refrigeration systems. It works across common refrigerants including high-pressure R-410A systems, making it suitable for a wide range of residential and light commercial service calls. The GLO-STICK capsule format is intended for fast, single-use dye injection at the manifold gauge set during routine service or leak diagnosis procedures.
Designed for use with the GLO-STICK air conditioner and refrigeration system. Suitable for small to medium systems using common refrigerants including high-pressure R-410A.
Installation is performed by a licensed HVAC or refrigeration technician. Connect the capsule at the low-pressure gauge port of a charged manifold gauge set and the system service port as directed by the GLO-STICK system instructions. Do not inject dye into a system that has been fully recovered and depressurized — the bleed valve injection method requires the system to be pressurized. After dye injection, use an appropriate UV or fluorescent leak detection lamp to locate leaks per the dye manufacturer's procedure.
