Multiquip 2113 Plug Fitting 1/8MP Hex Socket Head

The Multiquip 2113 Plug Fitting 1/8MP Hex Socket Head is a genuine OEM component designed for HTX44, MD, LD, and WRS series equipment. This precision-threaded 1/8-inch male pipe hex socket head plug delivers a secure, leak-free seal in hydraulic and fluid-circuit applications across the trowel and roller screed lineup. Verified fitment covers models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, MD105, MD80, LD60, LD6, WRSPUDF, WRS5200, and WRS5200DFPU. Sourced directly from Multiquip, part 2113 meets the exact specification of the original hardware installed at the factory.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 1/8-inch male pipe thread pitch and hex socket head dimensions required for a pressure-rated seal in Multiquip hydraulic circuits.
• Drop-In Hardware Replacement — Matches the original plug geometry and drive profile, seating correctly into the ported housing without rework or re-tapping.
• Broad Series Fitment — Confirmed for HTX44, MD, LD, and WRS series machines, including HTX44K4, HTX44Y5, MD105, MD80, LD60, WRS5200, and related variants.
• Fluid Circuit Integrity — A properly installed plug fitting prevents hydraulic fluid loss and pressure drop; a missing or damaged plug can cause immediate fluid weeping and loss of blade or drive system control.
• Hex Socket Drive — Internal hex socket head allows controlled torque application with a standard hex key, reducing the risk of rounding during installation or removal in tight machine cavities.

A plug fitting seals off an unused or access port in a hydraulic or fluid manifold, preventing fluid escape and maintaining circuit pressure throughout the system. On ride-on trowels and roller screeds, these ports appear across the hydraulic valve blocks, pump housings, and plumbing assemblies where the internal hex socket head design allows for precise torque in confined spaces. When a plug fitting is absent, cross-threaded, or cracked, it creates a pathway for hydraulic fluid loss that can starve the blade pitch or drive circuit, leading to erratic machine behavior or a complete loss of hydraulic function.
