Diversitech 16154 Regular Flux Paste 2 Oz

Product Description

The DIVERSITECH 16154 is a regular flux paste formulated for use in soldering and brazing applications across plumbing, HVAC, and refrigeration work. Flux paste promotes clean, oxide-free solder joints by chemically cleaning metal surfaces and preventing re-oxidation during heat application. This 2 oz container provides a convenient, field-ready supply for service technicians and installers working with copper tubing, fittings, and connectors. The paste consistency allows for controlled application directly to joint surfaces before soldering, helping to ensure consistent, leak-free connections in both new construction and repair scenarios.

This flux paste is suited for residential and light commercial applications where soft soldering of copper and brass components is required. Typical use cases include sweat-fitting copper water lines, refrigerant line connections, and HVAC coil or evaporator repair. Plumbers, HVAC technicians, and refrigeration service pros keep this type of flux on hand as a standard consumable for daily service work. The 2 oz size is practical for individual technicians or small service vans.

Key Features

• Paste formulation allows precise, mess-free application to joint surfaces
• Promotes clean solder joints by removing oxides from copper and brass surfaces
• 2 oz container sized for field use and individual service kits
• Compatible with standard soft soldering procedures on copper and brass
• Supports consistent, leak-free joint formation in plumbing and HVAC work

Compatibility

Designed for use as a general-purpose soldering flux paste for copper and brass fittings in plumbing, HVAC, and refrigeration applications. Verify suitability with specific solder alloys and applicable local codes before use.

Installation Notes

Flux paste is applied by licensed plumbers and HVAC technicians as part of standard sweat-soldering procedures. Shut off and drain water lines, or recover refrigerant and isolate the system section, before opening any joint for repair or replacement. Apply flux sparingly and evenly to clean, deburred surfaces only. Work in a ventilated area and follow all applicable plumbing and mechanical codes, including IPC and IFGC requirements for joint preparation and material compatibility.
