Maintenance and regular servicing are essential for efficiently functioning equipment. Charging hoses are used for installation, maintenance, HVAC systems, and more. Hoses are designed to prevent leakage of high-pressure refrigerants preventing a hazard-free system. DK Hardware offers various charging hoses and accessories for hassle-free installation and maintenance. The JB Industries Hose is ideal for use with standard refrigerants. The JB Industries Quick Seal Fitting Adapter can be used with the existing charging hose. They immediately trap refrigerant discharged from the hose when disconnected from the access fitting to reduce loss of refrigerant. The Porter-Cable Electric Air Compressor and 16-Gauge Nailer Combo Kit offer a range of tools that make this kit ideal for crown molding, staircases, and interior trim work.
