Frequently asked questions
Common questions about HARRIS from 3G Electric.
What are the pressure ratings for Harris gas regulators?
Harris regulators in the 3G Electric catalog include models with maximum inlet pressures up to 1,500 psig and outlet pressure ratings such as 125 psig. For example, the single-stage high-pressure air and inert gas regulator (SKU 30AA59) is rated for 1,500 psig inlet and uses a urethane diaphragm. The air and inert gas regulator (SKU 5KZ44) has a CGA 346 inlet and is rated for 125 psig outlet, with a neoprene diaphragm. Always verify the specific model's ratings against your system requirements.
What is the difference between Harris flashback arrestors and other safety devices?
Harris flashback arrestors, such as the 88-5FBHF-RR (SKU 5KZ79), are regulator-mount devices designed to prevent reverse gas flow and flame propagation into the regulator. They are compliant with CGA 022 for oxygen service and have a 9/16 in-18 connection. Other safety devices may include check valves or excess-flow valves, but flashback arrestors specifically address flame propagation. Selection depends on the gas, connection size, and installation location.
What types of Harris torch handles are available?
The Harris torch handle line includes the 43-2 series, a Harris-style handle with a 9-1/2 inch length and 9/16 in-18 inlet connection. It is used for oxy-fuel welding, cutting, and brazing. The handle provides gas flow control and a secure grip. Compatibility with other Harris components, such as heating nozzles and cutting tips, depends on the series and connection sizes. Check the specific part number for your application.
What is Harris Stay-Silv White flux used for?
Harris Stay-Silv White flux (SKU 54RY03) is a white paste flux formulated for use with phos-copper brazing alloys. It is supplied in a 5 lb jar and is used to clean metal surfaces and promote flow during brazing. Typical applications include HVAC and refrigeration piping. The flux is applied to the joint area before heating. It is not intended for use with all alloys; confirm compatibility with the brazing alloy being used.
What are the connection standards for Harris gas switchover systems?
The Harris gas switchover system (SKU 46Z590, MPN KH2004) features a CGA 580 inlet connection and a 1/4 in NPT female outlet. It is rated for 125 psig and is designed for high-purity gas service with helium leak integrity. The system automatically switches between two gas cylinders to maintain uninterrupted supply. It is suitable for argon, helium, and nitrogen. Verify the connection standards match your existing manifold and piping.
What heating nozzles does Harris offer for acetylene service?
Harris heating nozzles include the J-63 series, such as the J-63-3 (SKU 6XR32). This is a size 3 nozzle with a tube-and-head tip design, used with acetylene for preheating, bending, or straightening metal. The J-63 series is part of the Harris oxy-fuel equipment line. Nozzle selection depends on the required heat output and the torch handle being used. Confirm the tip size and series match your torch.
