Description

Veloci Prima Quick Connects – Built for Clean, Fast, Leak-Free Connections

When every job demands speed and reliability, Veloci Prima quick connects deliver. That’s because these fittings are designed with professionals in mind—those who can’t afford leaks, weak seals, or wasted time. Rather than settle for imported shortcuts, Veloci crafts every fitting right here in the USA to ensure top performance under pressure.

As a result, your connections stay tighter, work smoother, and last significantly longer in the field.


Built in America, Built to Last

Veloci manufactures every Prima fitting at its Minnesota facility. To start, they source raw 303 stainless steel bar stock from Pittsburgh—known as the City of Steel. Then, through in-house machining, polishing, and inspection, each fitting transforms into a high-precision connector made to outperform.

Because Veloci controls every step, quality never slips.


Packed with Performance-Driven Features

To support high-pressure cleaning professionals, Prima fittings include:

  • In-House Precision Machining
    Every fitting is machined from solid bar stock—not cast—so durability and precision always come standard.

  • Extreme Accuracy with Tight Tolerances
    Each part is crafted within ±127µm and ±1º for proper alignment and dependable sealing.

  • High-Grade 303 Stainless Steel
    This steel resists rust and withstands tough jobsite conditions without breaking down.

  • De-burred, Polished, and Washed
    Clean surfaces and smooth edges ensure fast, frustration-free connections every time.

  • EPDM Seals Built for Harsh Conditions
    These seals resist damage from heat and aggressive chemicals, lasting longer than standard rubber.

  • Digitally Measured for Consistent Fit
    Every piece undergoes digital inspection to maintain strict quality from batch to batch.

Thanks to these features, Veloci Prima fittings offer unmatched value and reliability.


Where They Work Best

Common Application Areas:

  • Between the pump and spray gun:
    Typically, this is where 3/8″ fittings are used, as they accommodate the high-flow demands and pressure output from commercial machines.

  • Lances and spray wands:
    Quick connects simplify accessory changes, saving time between jobs without compromising flow or seal integrity.


Understanding Thread Types

Before connecting, make sure you’re matching the right thread style:

  • Male Threads: Located on the outside of the fitting

  • Female Threads: Located on the inside of the fitting

  • All Threads Are NPT: This is the standard tapered thread style across North America

Choosing the correct thread type improves sealing and prevents damage.


Seal It Right: Installation Made Simple

Now that you’re ready to connect, follow these simple steps:

  • For NPT to NPT connections: wrap 4–5 layers of Teflon tape clockwise, or apply 2–3 drops of Loctite thread sealant.

  • For NPT to BSP (common in European fittings): use 6–7 wraps of tape or a slightly heavier dose of Loctite.

Even though BSP threads tighten sooner, you’ll still get a proper seal with enough thread treatment.
