Williams Comfort Products 43631 45 Degree Flaring Tool

Product Description

The WILLIAMS COMFORT PRODUCTS 43631 is a 45-degree flaring tool designed for creating leak-free flare connections on soft copper, aluminum, and brass tubing. Flare connections are a standard method for joining refrigerant lines, fuel gas lines, and potable water supply lines in HVAC, refrigeration, and plumbing applications. The tool produces a consistent 45-degree flare seat that meets industry standards for pressure-tight joints. At 2.134 pounds, it is a compact, field-portable hand tool suited for both shop work and on-site service calls.

This flaring tool is used in residential and light commercial applications wherever tubing connections require a mechanically formed flare rather than a brazed or compression fitting. Typical installations include refrigerant line sets for split-system air conditioning and heat pump equipment, as well as natural gas and LP appliance connections. HVAC technicians, refrigeration mechanics, and licensed plumbers rely on this type of tool when making field connections that must hold pressure and remain leak-free over the life of the system.

Key Features

• Produces a 45-degree flare angle compatible with standard flare fittings used in HVAC and plumbing
• Compact tool weight of 2.134 pounds supports easy transport to job sites
• Sold individually as a single unit for straightforward procurement
• Suited for soft copper, aluminum, and brass tubing common in refrigeration and gas line work

Compatibility

Designed as a standard 45-degree flaring tool for use with soft copper, aluminum, and brass tubing in HVAC, refrigeration, and plumbing service work. Specific compatible tubing sizes were not provided in the product data.

Installation Notes

This tool is typically used by licensed HVAC technicians, refrigeration mechanics, and plumbers. Before making any flare connections on refrigerant lines, recover all refrigerant and depressurize the system in accordance with applicable EPA Section 608 requirements. On gas lines, shut off the gas supply at the service valve before cutting or flaring tubing. Ensure cut tubing ends are deburred and properly sized before seating in the flaring bar to produce a clean, concentric flare seat.
