Veloci Prima Quick Connects – American Made, Engineered to Perform
Veloci produces all of the Prima fittings in house, right here in Minnesota. It starts with an unwavering commitment to quality. Machining. Polishing. Inspecting. We do it all in-house. That’s why performance remains consistent—not just month to month, but year after year.
We start with 303 stainless steel bar stock forged in Pittsburgh (yes, America’s steel city). So each fitting is not just strong. It’s also packed with legacy. Because every detail is in-house, Veloci has complete control. That means no outsourcing, no compromises, and no cutting of corners.
We’ve also completely eliminated the risk of degradation. You get long-term durability, exacting fit, and repeatable results. Job after job.
Precision Engineered for Continuous Duty
Above all else, Prima fittings are designed for pros. Since they’re engineered for heavy, daily use, they won’t quit when the pressure is on. Whether you throw heat, water, or caustic chemicals at them, they don’t flinch.
As a result:
- Connections remain smooth
- Changeouts are faster
- Leaks are history
- So when your reputation’s on the line, Veloci fittings never let go—EVERY TIME.
Features:
- In-House Machining: Precision machined from solid bar stock, not cast.
- Precision Fit: Constructed to within ±127µm and ±1º for an accurate fit every time.
- 303 Stainless Steel: Highly corrosion resistant and suitable for most harsh environments.
- Polished & De-burred: Precision machining with smooth edges, resulting in an easy, fast connection.
- EPDM Seals: Heat and chemical resistant seals for a long life span.
- Digitally Verified: Machined parts are verified to exact tolerances for consistent fit and feel on every part of every production run.
- Prima fits between the pump and spray gun, where it’s used the most for high-flow, continuous service. It’s also used on lances and wands to enable quick tool changes or at pressure points where fast disconnect is required after a cleaning cycle.
- Veloci Prima Quick Connects for a system that’s tight, tough and professional.

Driven by Innovation. Rooted in Quality. Focused on You.
Veloci Performance Products is more than a supplier—we’re your performance partner. As the exclusive U.S. provider of MTM Hydro products, we lead the industry in delivering high-quality pressure washing components and accessories trusted by professionals and DIY users alike.
Our journey began in 1977 when MTM Hydro, SRL was founded by the Costamagna family in Cherasco, Italy. In 2005, Scott Lindholm and Pierluigi Gallo partnered to bring MTM Hydro to Eden Prairie, Minnesota. With a focus on manufacturing for OEMs and distributors, the U.S. team quickly became a trusted name in pressure washing.
Following the unexpected passing of Scott Lindholm in 2011, his son Aaron Lindholm stepped in as President of the U.S. division. Over the next several years, Aaron listened to the market, rebranded the business, and launched Veloci Performance Products, Inc. By 2017, he officially became President and CEO after acquiring the U.S. operation from MTM Hydro SRL.
Today, Veloci continues to build on its legacy. Our mission is clear: to provide premium products backed by strategic support, exceptional service, and a commitment to raising industry standards. From the warehouse floor to global distribution, everything we do is grounded in one word—quality.
