MERWOF Handheld Tubing Straightener 3/8-Inch OD for Brake, Fuel Lines & Copper/Aluminum Coils

Overview

The MERWOF Handheld Tubing Straightener is a compact, lightweight tool designed to straighten 3/8-inch OD coils with ease. Its handheld form lets you control the process with one hand, whether you’re on a busy workbench, in a shop, or roadside repairs. This tool accommodates a range of common metals including copper, brass, aluminum, and stainless steel, providing flexible options for various projects.

Construction and Feel

Durability comes from a robust combination: an aluminum alloy inner roller and an outer shell built from four ABS plastic pieces.

The distinctive green and black finish adds character to your toolbox while helping you spot it quickly in a crowded drawer.

What You Get

• 1 x 3/8-inch Handheld Tubing Straightener

Key Benefits

Usage Tips and Considerations

• Before insertion, ensure the tube end is smooth and not deformed to prevent binding
• For thicker copper tubes, bend the end slightly straighter before feeding into the tool

Materials and Compatibility

Designed for 3/8-inch OD coils, it supports copper, brass, aluminum, and stainless steel. This versatility is useful for brake lines, fuel lines, and other small-diameter metal runs. For copper, especially thicker tubes, bending straighter before insertion can help feed into the tool more smoothly.
