Mosmatic Live Pressure Washer Swivel DGV – 4000 PSI, 3/8 in NPT-M, Stainless Steel

Meet the Mosmatic Live Pressure Washer Swivel, Model DGV—the compact, high‑performance choice for clean, controlled water delivery under tough conditions. Engineered for reliability, this swivel supports demanding workflows with a robust pressure rating and durable materials, helping you maintain fluid movement across lengthy cleaning sessions.

Key advantages you can expect

At the heart is a high‑pressure design rated to 4000 psi (27.5 MPa). This provides steady flow when you’re blasting away grime on vehicles, equipment, or exterior surfaces. The unit is built to tolerate hot‑wash tasks, with a temperature rating up to 250°F, which supports hot‑water cleaning options when your system allows. The exterior shell uses brass with a nickel plating, while the inner portion is stainless steel—delivering a durable, corrosion‑resistant core for daily use in busy environments.

• High‑pressure capability: up to 4000 psi for demanding cleaning tasks.
• Heat tolerance: up to 250°F to support hot‑water cleaning options.
• Rugged construction: brass, nickel‑plated exterior; stainless steel inner part.
• Sealing options: NBR O‑ring standard, with EPDM or FKM variants available for specific fluids or environments.

The Mosmatic swivel is designed for fluid and media versatility. It handles fluids in a pH range of 3–12 when using properly filtered liquids, and it can be used with 10‑micron filtration to help protect the seal and moving parts. For certain workflows, compressed air up to 290 psi can be used, enabling integrated cleaning routines where air assists the wash. The connections are standard and straightforward: G1 3/8" NPTM inlet and G2 3/8" NPTF outlet, making it easy to pair with common hoses and spray wands. The compact footprint—NW 1/4" with an overall length around 2.75" and a short 0.43" secondary length—keeps weight light at about 6.2 oz and reduces fatigue during extended jobs. Two wrench sizes are provided to help you service the unit without dragging out a full toolkit.

In practical terms, a few simple setups can improve your workflow: mount the swivel near the spray gun to minimize hose torque, maintain smooth turning during washes to extend hose life, and inspect seals and threads during routine maintenance to preserve consistent rotation and leak resistance. This component isn’t a guaranteed outcome, but it’s designed to contribute to steadier handling, reduced hose twist, and a cleaner work process when used as part of a complete cleaning system.
