TurboForce THQS1 90° Upper Gun Swivel
The TurboForce THQS1 is the 90-degree high-pressure upper gun swivel used on select TurboForce tile and grout cleaning tools. It installs between the trigger gun and incoming high-pressure solution hose, allowing the hose connection to rotate and helping reduce hose twisting, binding, and operator fatigue.
This swivel cross-references to Mosmatic 32.548 and may also be identified under several current or previous TurboForce/OEM part numbers, including THQSL, THQSI, THQS1, and 25730.

Where Is This Swivel Used?
The THQS1 is commonly used as the upper gun swivel on TurboForce hard-surface and tile cleaning equipment. On compatible tools, it mounts between the trigger gun and the incoming high-pressure solution hose.
The 90-degree configuration provides a more natural hose angle while the swivel allows rotation during operation. This can reduce twisting and stress on the pressure hose, fittings, and trigger-gun connection.
Why Replace the Gun Swivel?
High-pressure swivels are wear components. Replacement may be necessary if the original swivel begins leaking, becomes difficult to rotate, develops excessive movement, or no longer allows the pressure hose to rotate smoothly.
IMPORTANT — VERIFY THREAD SIZES BEFORE ORDERING
This swivel uses a 3/8" NPT male connection × 1/4" NPT female connection. Similar-looking high-pressure swivels are available with different thread configurations.
Please verify your existing swivel and connection sizes before ordering.
