IMPERIAL
Frequently asked questions
Common questions about IMPERIAL from 3G Electric.
What refrigerants are compatible with IMPERIAL Series 400 manifold gauge kits?
IMPERIAL Series 400 manifold gauge kits, such as the 421-C and 496-C models, are designed for use with R-22, R-404A, and R-410A refrigerants. The 496-C variant is also compatible with R-12 and R-502. These kits include two valves and three hoses, with color-coded connections for low and high sides. Always verify the specific model's refrigerant compatibility before use, as some models are optimized for particular refrigerant types.
What tube sizes can the IMPERIAL 525-F flaring tool accommodate?
The IMPERIAL 525-F flaring tool is a single 45-degree handheld tool that accommodates tube sizes of 1/2 in, 1/4 in, 3/8 in, 3/16 in, 5/8 in, and 5/16 in. It is constructed from aluminum for reduced weight and is suitable for creating flares on copper, brass, and aluminum tubing. The tool uses a cone and clamp mechanism to form consistent 45-degree flares for refrigeration and HVAC connections.
Does IMPERIAL offer a tube bender with angle markings for precise bends?
Yes, the IMPERIAL 364-FHB-04 lever-style tube bender includes angle markings from 0 to 180 degrees, allowing for precise bends. It is designed for thin-wall steel tubing with a maximum outside diameter of 1/4 in and a bend radius of 9/16 in. The bender is suitable for HVAC and refrigeration line sets where accurate bend angles are required to avoid kinking.
What materials can the IMPERIAL 275-FSC tube working kit handle?
The IMPERIAL 275-FSC tube working kit is designed for flaring and swaging operations on aluminum, brass, copper, stainless steel, and steel tubing. It includes a self-centering mechanism for consistent flares and comes in a tool case for portability. The kit supports single 45-degree flares and is suitable for field service and workshop applications.
Are IMPERIAL manifold gauge kits available with gauge boots for impact protection?
Yes, many IMPERIAL manifold gauge kits, including the Series 400 and Series 600 models, come with gauge boots. For example, the 421-C, 651-C, 631-CKP, and 496-C all include gauge boots to protect the gauges from drops and impacts during transport and use. The boots are typically made of rubber or synthetic material and fit over the gauge housing.
What is the head size configuration of the IMPERIAL 127-CO box end wrench?
The IMPERIAL 127-CO box end wrench is a 4-in-1, 4-point ratcheting wrench with head sizes of 1/4 in, 3/8 in, 3/16 in, and 5/16 in. It is made of chrome-finished steel and has an overall length of 5 3/8 in. The ratcheting mechanism allows for quick tightening or loosening of fasteners without repositioning the wrench.
