The Multiquip 12138 Clamp Base 3/8 Tube Double is a genuine OEM component designed for STH series hydrostatic ride-on trowels. Sourced directly from Multiquip, this part meets the exact specifications of the original and installs as a direct replacement with no adaptation required. The 12138 is the correct part for STH hydrostatic trowel applications where a double 3/8-inch tube clamp configuration is specified.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the clamp delivers the correct clamping force and tube retention for a 3/8-inch double-tube configuration.
- Direct-Fit Replacement — Matches the original mounting geometry of the STH series hydraulic plumbing layout, dropping into position without rework or hardware changes.
- STH Series Compatibility — Confirmed fitment for STH hydrostatic ride-on trowels, making it straightforward to cross-reference against your machine before ordering.
- Secure Tube Retention — A properly seated clamp base keeps hydraulic or fuel lines firmly routed and protected against vibration-induced wear, chafing, and loosening during operation.
- Correct Hardware for Hydraulic Line Integrity — Using the specified OEM clamp base on hydraulic lines reduces the risk of line movement under pressure, supporting safe, consistent trowel performance.
A clamp base secures tubing and hose lines to the machine's frame or structure, holding them in a fixed, protected position during operation. On hydrostatic ride-on trowels, where hydraulic lines route power to the blade pitch and drive systems, secure tube routing is essential — unsupported or shifting lines are vulnerable to abrasion, stress cracking, and fitting loosening over time. The double 3/8-inch configuration of the 12138 accommodates two lines running in parallel, keeping both routed cleanly and reducing the chance of contact wear between adjacent tubes.
