What GB Connections does
GB Connections (GBC) is a privately held Houston-based engineering company that designs, licenses, and supplies semi-premium casing connections for the oil and gas drilling industry. Founded in 1980 and operating as an independent company since its 2017 spin-off from a parent tubular division, GBC has accumulated over 45 years of field experience and 400+ million feet of installed GB CD/CDE connections across deepwater, offshore, unconventional, and extended-reach drilling applications worldwide. The company serves three primary customer segments — operators, OCTG distributors, and pipe mills — with a portfolio organized around three core connection families: GB Buttress (5P) covering 4.5"–20" OD casing, GB 4P covering 10.75"–13.375" OD, and GB 3P covering 16"–20" OD. Each family includes application-specific variants such as GB CD (Casing Drilling), GB CDE (Casing Drilling Enhanced for heavier walls), GB CD Slim Hole (tight annular clearance), GB CD RDB (Reduced Drag Bullet Nose), GB CD EHTQ (Extra High Torque), and WS/HB/WSE/HBE (wear sleeve / hard band for abrasive environments). The underlying technology is protected by multiple US patents and relies on proprietary thread geometries, exclusive gauging techniques, and benchmark torque ratings.
GBC operates a direct enterprise field-sales model with a small in-house commercial team and quote-based pricing tied to casing OD, grade, weight, and coupling specifications. Revenue is generated through three streams: hardware sales of proprietary connections, technical services and field support, and licensing of authorized threading, repair, and accessory facilities. The company has built a global authorized facility and trained third-party running company network spanning Texas, Louisiana, Oklahoma, Colorado, Wyoming, North Dakota, Ohio, West Virginia, Canada, Alaska, Singapore, and Indonesia — enabling local threading, repair, and running services without owning physical service assets. Marketing is executed through a technical content-led website (including an online Data Sheet Generator), industry white papers, case histories, and relationship-based selling by senior leadership. Following the June 2024 appointment of Robert L. Kovar as President & CEO, the company has invested in leadership bench depth, expanded engineering and sales capacity, and signaled an intent to scale beyond its prior lean operating model while preserving founder Gene Mannella's technical continuity in an advisory Chairman/Executive Technology Officer role.

GB Connections competitors and assessment
Company assessmentDirect peers
- TMK (TMK Group): TMK operates the TMK IPSCO brand and proprietary connection families (e.g., ULTRA, TMK PF) serving the same drilling-with-casing and offshore segments as GB Connections. TMK IPSCO is also where GBC's VP Operations previously worked, indicating direct talent and competitive overlap.
- Workstrings International (Superior Energy Services): Workstrings provides drill string and casing connections, rental tools, and tubular running services, directly competing with GBC in drilling-with-casing applications. Both companies serve operators in onshore unconventional and offshore markets with comparable connection technologies.
- Vallourec: Vallourec owns the VAM connection brand, historically co-developed and now competing head-to-head with GB Connections' GB CD/CDE thread families in offshore, deepwater, and unconventional applications. Direct competitor for premium and semi-premium connection sales to global E&P operators.
- Tenaris: Tenaris is the world's largest OCTG manufacturer and operates the VAM premium connection family, the most direct competitor to GB Connections' semi-premium offerings. Tenaris Blue and VAM connections serve the same drilling-with-casing and deepwater applications across overlapping customer sets of IOCs and NOCs.
- Hunting Energy Services: Hunting provides OCTG connections and threading services globally and is both a direct competitor to GB Connections' proprietary connections and an authorized threading facility for GBC products. Overlapping product lines in semi-premium connections for drilling and completion applications.
Broad incumbents
- Weatherford International: Weatherford offers proprietary OCTG connections and tubular running services as part of a broader oilfield services portfolio. While not as specialized as GBC in semi-premium casing connections, Weatherford competes in the same drilling-with-casing and premium tubular segments.
- NOV (National Oilwell Varco): NOV's Grant Prideco and Tuboscope divisions offer proprietary OCTG connections (XT, Atlas Borealis) plus threading and inspection services that overlap with GB Connections' product and authorized-facility model. NOV is both a competitor and a channel partner through NOV Tuboscope South.
Emerging players
- Tejas Tubular Products: Tejas Tubular Products is a smaller OCTG threading and connection provider focused on the US Gulf Coast and Permian Basin, overlapping with GBC's authorized facility network and semi-premium connection offerings in domestic markets.
