Tube Expanders for Impact Wrenches

Use the power of an impact wrench to stretch the ends of metal tubing, allowing another tube with the same diameter to fit inside.

Hammer-Driven Tube Expanders

Using a hammer, tap these expanders into the end of a tube to allow a second piece of the same diameter to fit inside.

Tube Expanders

Enlarge the end of a tube to allow a second piece of the same diameter to fit inside.

Tube Expanders for Condensers,
Heat Exchangers, and Boilers

Designed for building and maintaining equipment with tubes that pass through perforated metal sheets, these expanders have rollers and tapered noses to ensure uniform tube tightness.

Hammer-Driven Tube Flarers for 45° Flares

Tap this tool with a hammer to quickly form 45° flared ends in copper tubing.

Hand-Held Tube Flarers for
Single and Double 45° Flares

Double flares roll the end of tubing in on itself then flare both layers for applications such as brake lines.

Hand-Held Tube Flarers for 45° Flares

Form 45° flares in aluminum, brass, or copper tubing so it’s compatible with flared tube fittings often used in low-pressure plumbing, air conditioning, and refrigeration systems.
