About Stucchi USA
Keeping hydraulic equipment productive often comes down to having the right connection for the job. Stucchi USA works with equipment owners, fleet managers, distributors, and OEMs to solve connection challenges that affect uptime, safety, and hydraulic system performance.
The Stucchi story began in Italy in 1960, when brothers Innocente and Lorenzo Stucchi founded the company. As Stucchi grew, it developed specialized expertise in hydraulic quick couplings and connection systems. Stucchi USA was established in 2002 to bring that experience closer to North American customers through responsive service, technical guidance, and reliable product availability.
Today, Stucchi offers flat-face, threaded flat-face, connect-under-pressure, high-pressure, multi-coupling, and custom-engineered hydraulic solutions. These technologies help customers control contamination, minimize fluid loss, manage residual pressure, and improve attachment changeovers across demanding hydraulic applications.
Stucchi USA helps customers identify and size couplers, troubleshoot recurring connection problems, and select the appropriate solution for their equipment. Customers have access to direct North American engineering support with sizing guidance and CAD models, and in-stock orders received by 4:30 p.m. Central ship the same day.
From an Italian Machine Shop to a Global Hydraulic Connection Specialist
The Stucchi story began in 1960 in the province of Bergamo, Italy, when brothers Innocente and Lorenzo Stucchi opened a precision screw-machine shop in Pagazzano. As the business grew, the brothers brought their machining expertise into hydraulic connection technology, developing reliable ways to connect and disconnect lines carrying pressurized fluid.
Over the decades that followed, Stucchi grew from an Italian machine shop into an international specialist in hydraulic quick couplings and connection systems. Our history reflects continued product development, a direct role in establishing the ISO 16028 flat-face standard, and steady expansion into markets worldwide.
How Stucchi Helped Shape the ISO 16028 Flat-Face Standard
Before international standards established a common flat-face coupling interface, manufacturers were introducing their own designs and demonstrating the advantages of flat-face technology over traditional poppet-style couplers. Stucchi launched their flat-face coupling series in 1983 and became the first coupling manufacturer to offer flat-face couplers in sizes larger than the standard 1/2-inch connection.
Giovanni Stucchi, an engineer and the son of cofounder Lorenzo Stucchi, chaired the international committee responsible for developing ISO 16028, Hydraulic fluid power — Dimensions and requirements of quick-action couplings, flush-face type. With Giovanni leading the standardization work and Stucchi’s flat-face profile already established in the market, the Stucchi design’s interface dimensions became the basis for ISO 16028, adopted in 1999. Stucchi’s engineering helped set the common flat-face interface the global hydraulic industry continues to follow.
ISO 16028 defines the interface dimensions and performance requirements for flat-face hydraulic quick couplings. Coupling halves from different manufacturers can connect when both conform to the same ISO 16028 interface and nominal size. Interchangeability does not mean every coupling offers the same performance, however. Buyers must still compare working pressure, flow capacity, materials, seals, and connect-under-pressure capability.

Product Development Driven by Field Problems
Stucchi develops hydraulic connection technology around the operating conditions customers face in the field. From contamination and fluid loss to residual pressure, pressure impulses, and hose torque, each challenge creates an opportunity to improve how hydraulic equipment connects and performs.
Examples of that continued product development include:
- Flat-face and threaded flat-face couplings: Stucchi flat-face technology provides zero-spill performance that helps minimize fluid loss and contamination during connection and disconnection. The progression from the VP Series through the VEP, VEP HD, and VEP HDL shows how Stucchi has continued adapting threaded flat-face technology for residual pressure, heavier-duty applications, and greater connection security.
- Connect-under-pressure solutions: Stucchi couplings designed to connect under residual pressure help operators reconnect attachments when pressure remains trapped in the hydraulic circuit. These solutions address a common field problem on construction equipment, mobile machinery, and frequently changed attachments.
- Solutions for hose movement and torque: The VT17-ZN Rot-Lock combines a threaded flat-face connection with an integrated live swivel, allowing the hose to rotate during operation and helping reduce the stress that contributes to leakage and premature wear.
- Multi-coupling and engineered systems: Stucchi multi-coupling plates connect several lines in one controlled movement, while custom connection systems address equipment-specific requirements involving flow, pressure, mounting space, and hose routing.
These are a few examples of how Stucchi continues to advance coupling technology as equipment designs and application demands evolve. Customers also have access to direct North American engineering support with sizing guidance and CAD models to help identify, configure or develop the appropriate connection system.
