Our Story

The Liner Hanger Specialist

Allamon Tool Company was founded in 1997 in Montgomery, Texas with a single-minded purpose: build the most reliable liner hanger systems in the oilfield. While other tool companies diversified across every completion category, ATC stayed focused.

That specialization created depth. Our engineers don’t split their attention across fifty product lines — they know liner hanger systems, running tools, and completion equipment because that’s all we do. When an operator runs an ATC tool, they’re getting 27 years of collective focus at the bottom of the hole.

Today, ATC tools are run across the Permian, Haynesville, Midcontinent, Gulf Coast, and Williston Basin. We’re expanding internationally as an OEM supplier — and we’re launching Endeavor™ flotation equipment and the Tomahawk™ Wet Shoe — ATC’s new premium float product line — in 2026.

How We Work

What ATC Stands For

Specialist Focus

We do one thing: liner hanger systems. That depth of knowledge shows in every tool we manufacture.

American Made

Every tool is manufactured in Montgomery, Texas — CNC machined, heat-treated, and 100% pre-ship function tested before it leaves our facility.

 
Operator Trust

We’ve built relationships with operators across 5 U.S. basins over 27 years. That trust is earned one successful run at a time.

 
Engineering First

Every new product starts in our engineering team — not in a marketing meeting. If the physics don’t work, the product doesn’t ship.

 
Manufacturing

20,000 Square Feet. Built in Montgomery.

Our manufacturing facility in Montgomery, Texas is where 85% of ATC tool production happens — in-house. CNC machining, heat treating, assembly, and 100% pre-shipment function testing, all under one roof.

We keep manufacturing close to home on purpose. It means we control quality at every step, respond faster to custom specs, and deliver with the confidence that comes from seeing every tool through from raw material to shipping crate.
