Mosmatic 32.548 DGK 90° High-Pressure Swivel
The Mosmatic 32.548 DGK 90° swivel is a compact, professional-grade high-pressure rotary union designed for pressure washer guns, hose connections, wash-bay equipment, hydraulic applications, and other installations where a hose or fitting must rotate freely while under pressure.
Its 90-degree configuration is particularly useful when space is limited or when you want to reduce hose twisting and operator fatigue. The swivel allows live rotation while the system is pressurized, helping prevent hoses from binding, kinking, and twisting during operation.

Designed for Live Rotation Under Pressure
The Mosmatic DGK design uses a single thrust ball bearing to provide smooth rotation with low operating torque. This allows the swivel to rotate while the pressure washer or fluid system is operating, making it an excellent choice for installations where hose movement is frequent.
Common Applications
- Pressure washer spray guns
- High-pressure hose connections
- Car wash and wash-bay equipment
- Ceiling boom hose systems
- Industrial cleaning equipment
- Hydraulic hose applications
- Hose reel and tangle-reduction installations
Compact 90° Configuration
Unlike a straight inline swivel, the 90-degree DGK configuration changes the direction of the hose connection while still permitting rotation. This can help create a more comfortable hose angle at the spray gun and reduce strain on the hose, fittings, and operator.
IMPORTANT — VERIFY CONNECTION SIZE BEFORE ORDERING
Mosmatic manufactures DGK swivels in several similar thread configurations. This 32.548 model has a 3/8" NPT male connection on one side and a 1/4" NPT female connection on the other side. Please verify both thread sizes before ordering.
