STAUFF MCS Multi Coupling System

STAUFF multi‑couplings allow the simultaneous, spill‑free connection of two to six hydraulic lines in sizes ranging from DN 6 (¼”) to DN 25 (1”), even when residual pressure is present. Built with integrated flat‑face quick‑release couplings and manufactured from high‑strength materials such as steel, aluminium or reinforced plastics, they ensure a secure, vibration‑resistant lock via an ergonomic hand lever—without tools. With operating pressures up to 350 bar (5076 PSI), high flow capacities and optional electrical inserts, they are ideal for mobile and stationary applications requiring fast and reliable attachment changes.

Multi couplers for hydraulics

STAUFF multi couplings for hydraulics enable the simultaneous, low-leakage connection of multiple hydraulic lines in a single coupling operation. As part of the STAUFF MCS Multi Coupling System, these hydraulic multi couplings are designed for applications where attachments or hydraulic consumers are regularly connected, disconnected or changed. multi couplings reduce set-up times, minimise oil loss and increase operational reliability in mobile and stationary hydraulic systems.

Hydraulic multi couplings for multiple lines

A hydraulic multi coupling combines several individual couplings in a single housing. STAUFF multi couplings enable two to six hydraulic lines to be connected or disconnected simultaneously. Integrated flat-face quick-release couplings ensure a clean, drip-free connection. The hydraulic multi coupling is particularly suitable for systems where short downtime, repeatability and safe handling are required.

Design and operation of STAUFF multi couplings

The STAUFF MCS Multi Coupling System consists of a fixed coupling half on the machine side and a detachable coupling half on the attachment or unit. The hydraulic quick-release couplings are directly integrated into both halves. During coupling, all lines are connected simultaneously and securely locked via an ergonomic hand lever. The multi coupling is designed to withstand vibrations and can be operated without tools.

Variants, nominal diameters and connections of multi couplings

STAUFF multi couplings are available in various designs and cover a wide range of applications. The multi couplings for hydraulic systems are designed for two, four, five or six lines and are available in nominal diameters from DN 6 (¼”) to DN 25 (1”). Depending on the size, operating pressures of up to 350 bar are possible. The multi couplers are compatible with standard connection threads such as BSP, NPT, UNF or metric threads and can be integrated into international hydraulic systems.

Materials and finishes for hydraulic multi couplings

STAUFF hydraulic multi couplings are manufactured from high-strength materials such as steel, aluminium or reinforced plastics. In addition, high-quality surface coatings are used to ensure reliable corrosion protection. This makes hydraulic multi couplings suitable even for demanding operating conditions involving dirt, moisture or high mechanical stresses.

Typical applications for hydraulic multi couplings

STAUFF multi couplings are used wherever several hydraulic lines need to be connected quickly and securely. Typical applications include agricultural and forestry machinery with interchangeable attachments, construction and mining machinery, municipal vehicles, as well as industrial and stationary hydraulic systems. Even in the presence of residual pressure, suitable multi couplings enable safe coupling with minimal fluid loss. 1

Accessories and extensions for multi couplers

STAUFF offers a comprehensive range of accessories to complement the hydraulic multi couplings. These include docking stations for the safe storage of loose coupling halves, protective caps to prevent contamination, and optional electrical inserts. This allows multi couplers to be used as a combined interface for hydraulic and electrical connections.

Technical advantages of STAUFF multi couplings

STAUFF multi couplings support the efficient and safe operation of hydraulic systems. The simultaneous connection of multiple lines reduces installation times and prevents incorrect connections. Flat-face coupling inserts minimise oil loss and contamination, whilst the robust locking mechanism via the hand lever ensures a reliable connection even under vibration and high pressures.
