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 260 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.
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 250 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 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.

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.
Thank you, Freedom Service Dogs of America for another great Faces of Freedom Clay Shoot in Midland. This is always a fantastic event, and our team had a blast. Thank you for all you do to serve our veterans and people with disabilities. We are proud to be a small part of what you do!

Thank you, Liberty Energy, for the invite to attend your Calgary golf tournament! We had so much fun, especially when the sun finally made an appearance! We loved that the Happy Gilmore putter was such a hit for the raffle, and we are proud to help raise money for Heads Up Guys, the world`s leading resource for men`s mental health. Thank you for a great event!

This weekend we honor the hard work that keeps our industry moving. This Labor Day, we`re grateful for the dedication of the crews who make progress possible - both in the field, on the road, and in our manufacturing facilities. Wishing everyone a safe and well-earned holiday!

Definitely one of our favorite events of the year! Come and join us on Friday, September 5th at the Faces of Freedom Clay Shoot. Our Yellow Jacket Team will be there shooting as well as hosting a station. This fantastic day benefits Freedom Service Dogs of America, an organization that provides service dogs to people with disabilities. We hope to see you there!

Best of luck to our summer engineering intern, Timothy So! He jumped into every engineering challenge we threw his way this summer. Good luck on your final semester, and we wish you all the best in your next chapter!

Congratulations to the Canada Stars and their coach, our Canadian Operations Manager, Matt Hunter! They traveled all over Europe, competing in the Lions Cup in Finland 🇫🇮, and made a big impression! They left it all on the ice and are bringing the U16 Cup 🏆 back to Canada 🇨🇦. Congratulations, girls, we`re thrilled that Yellow Jacket could be a part of helping you bring home the victory!
