G&H began as a tool and die shop in 1958 with a handful of employees. We manufactured a variety of precision-stamped specialty products used by operators and service companies to drill and complete oil and gas wells.

On a wellsite, our products were only a small part of a complex system of equipment and procedures, but the quality of these products mattered greatly. A product that was improperly manufactured, structurally flawed, or not delivered on time could undermine safety or cause downtime and operating costs to soar. Uncompromising quality has always been essential. Through determined effort, both G&H and our products developed a reputation for dependability.

By 2010, we were experiencing remarkable growth in demand for perforating guns built to the highest level of quality and delivered faster than any of our competitors.  In 2011, G&H launched its own patented line of perforating guns under the trade name Yellow Jacket Oil Tools™.  A few years later, G&H launched the industry’s most reliable line of patented frac plugs, under the trade name M1™.  Following our belief in change for the better, we set course to become the industry’s “Plug & Perf Powerhouse™.”

Today, G&H employs over 350 people. We have 230,000 sq ft of manufacturing space between our ISO 9001:2015 certified manufacturing facilities in Northwest Houston.  Manufacturing in Houston provides abundant access to an experienced labor pool and competitive pricing on raw materials.  It is our strategic advantage over our competitors.  We have earned 12 U.S. patents (awarded and pending).

With over six decades of accumulated knowledge, innovative research and development in materials and processes, and state-of-the-art production and inspection equipment, our craftsmanship and capabilities are unmatched.
