WHO WE ARE
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 300 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 52 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.
We are truly a powerhouse, but one intent on living up to our motto,
“ALWAYS BUILDING, ALWAYS BETTER.”

G&H began as a tool and die shop in 1958 with a handful of employees. 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 machined, 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 the early 1990s, we were experiencing remarkable growth in demand for two product lines in particular: perforating guns and expendable plugs. Following our belief in change for the better, we adjusted our business model accordingly and set about becoming the industry’s “Plug & Perf Powerhouse.”
Today, we employ over 300 people. We have 120,000 sq ft of manufacturing space at our ISO 9001:2015 certified manufacturing facility in Northwest Houston. We operate strategically located warehouses in major U.S. oil and gas producing regions. We have earned 52 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.

THE LEGEND
Since acquiring G&H in 1983, Ed and Janan Kash dedicated their business to taking a personal interest in customer’s success – no matter how large or small. Unrivaled devotion to clients, staff, and engineers not only led to explosive growth for G&H, but ultimately set wholesome roots and innovative standards for the future of manufacturing. Though Ed still likes to play with industrial grade lasers, you’ll likely spot him and the Mrs. at the family ranch enjoying retirement.

THE LEGACY
Jimmy and Danny Kash, sons of Janan and Ed, are the fearless leaders propelling G&H to greater heights. Growing up around the business has inspired them to continue the company’s legacy of providing high-quality metal products and dedicated customer service, all while pushing themselves to expand the business in new, innovative directions. With their bold and creative vision, the future looks bright with the next generation in leadership.
THE FUTURE
G&H ranks number one among our competitors for perforated guns and number five among our competitors for expendable plugs. We have sold over 7.6 million perforating guns in the last ten years alone and our products have been used in 135 unique customer locations. Our client roster is intensely loyal and includes all industry leaders in upstream oil and gas. The goal is simple: be number one and stay number one. Through constant product innovation and recruitment of talented team members, we never stop evolving and shaping our future.
ALWAYS Building…ALWAYS Better.
BOTTOM-SET PLUGS DON’T WORK BECAUSE PLUGS NEED A BACKBONE!
Composite plug users understand the basics: a plug needs structure to hold isolation under pressure. That structure comes from the mandrel.
The mandrel keeps the slips engaged and maintains compression on the sealing element. Remove it, and the entire plug relies on components that can move or relax under load.
Bottom-set dissolvable plugs removed the mandrel to save material cost. In doing so, they removed the backbone of the plug.
The M1NT™ dissolvable plug keeps the mandrel where it belongs - providing the structure required to hold isolation when pressure builds.
M1NT. Top-set for a reason.
The data is finally catching up to what the field already knows. Bottom-set dissolvable plugs were built to reduce material cost - not to maximize isolation. In the early days of dissolvable technology, magnesium was extremely expensive. To keep plug prices down, designs were shortened, and the mandrel was removed. That’s how the bottom-set design was born.
But anyone who has run composite plugs understands the basics: plugs need length, mass, and a backbone. The mandrel provides that backbone. Remove it, and you sacrifice the structure required to hold isolation under pressure. When isolation fails, the savings disappear.
‣ The M1NT™ Dissolvable Plug is the only true Top-Set dissolvable on the market.
From day one, Yellow Jacket chose design integrity over cost-cutting. As the cost of dissolvable magnesium has dropped, so has our barrier to entry. Our price point in now attractive to operators trying to find a dissolvable plug that works 99.9985% of the time.
Recent reports from DarkVision and others suggest bottom-set dissolvable plugs fail at rates approaching 40%. Our trial results have many of the top operators rethinking shutting down their dissolvable programs. There’s a reason composite plugs dominate isolation completions: the majority of composite plugs are top-set.
The M1NT™ dissolvable frac plug delivers market-leading isolation – at prices you can afford. M1NT is top-set for a reason. Don’t continue to let bottom-set plugs disappoint you. Call us!

Who says manufacturing can’t have heart?
Today, our shop had a very special visitor delivering Valentine treats — and making herself right at home.
She toured production, checked out a perf gun build, inspected a frac plug, and even jumped on a forklift to help load a truck.
Sweet treats. Serious tools. That’s how we do it.
Happy Valentine’s Day from America’s Plug & Perf Powerhouse. 💛
