What are metric flare nut wrenches used for?

Metric flare nut wrenches, also known as line wrenches, are specifically designed for loosening and tightening nuts on fluid lines, such as brake lines, fuel lines, and hydraulic lines. Their unique design, with a partial opening that wraps around the nut, helps prevent rounding or damaging the fitting, which is common with standard open-end wrenches.

What sizes of metric flare nut wrenches are typically available?

ToolSource offers a wide range of metric sizes to accommodate various applications. You'll find individual wrenches and sets covering common sizes like 8mm, 10mm, 12mm, 13mm, 14mm, 17mm, and 19mm. Consider the specific sizes needed for your work when selecting your wrenches.

What should I look for when choosing a metric flare nut wrench?

When selecting a metric flare nut wrench, consider the material, finish, and jaw angle. Look for wrenches made from durable materials like alloy steel for strength and longevity. A chrome finish provides corrosion resistance. Also, consider the jaw angle, as some wrenches have angled heads for better access in tight spaces.

Which brands of metric flare nut wrenches does ToolSource carry?

ToolSource offers a selection of metric flare nut wrenches from reputable brands known for their quality and durability. You can find options from SK Hand Tool, Sunex Tools, Stanley Proto Industrial Tools, J.H. Williams, GearWrench, K Tool International, VIM Tools, and V8 Tools, among others.

Are metric flare nut wrench sets available?

Yes, ToolSource offers metric flare nut wrench sets, which provide a convenient and cost-effective way to acquire a range of common sizes. Sets are particularly useful for mechanics and technicians who frequently work on different types of fluid lines. Consider a set if you need multiple sizes for various applications.

What's the difference between a standard wrench and a flare nut wrench?

The primary difference lies in the design of the wrench head. A standard open-end wrench has a completely open jaw, while a flare nut wrench has a partial opening that wraps around more of the nut. This design provides better grip and reduces the risk of rounding the corners of the nut, especially on softer materials like brass or aluminum often found in fluid lines.

What materials are metric flare nut wrenches typically made from?

Metric flare nut wrenches are typically made from high-strength alloy steel, often with a chrome or black oxide finish. The alloy steel provides the necessary strength and durability to withstand the torque required for tightening and loosening fittings. The finish helps to prevent corrosion and extend the life of the wrench.

Can I use a metric flare nut wrench on automotive brake lines?

Yes, metric flare nut wrenches are specifically designed for use on automotive brake lines and other fluid lines. Their design helps prevent damage to the fittings, which is crucial for maintaining the integrity of the braking system. Using the correct size flare nut wrench is essential to avoid rounding the nut.
