Forming Kit – 6 mm Common Rail Diesel Pipes

The Marbed 9376-DP6CR forming kit is specifically engineered for 6 mm common rail diesel pipes. Unlike conventional diesel pipes, common rail lines are much harder and more rigid, and they require a special stepped cone profile at the pipe end to withstand extreme operating pressures. The DP6CR kit guarantees safety, sealing, and repeatability when paired with the Marbed 9376-D 20-ton press.

Key Benefits

• Dedicated kit for 6 mm common rail diesel injection pipes

• Stepped cone profile ensures correct sealing under very high pressures

• Includes forming die, half-shells, and protrusion gauge

• Conical retaining system ensures absolute tube stability under load

• Modular system: build your toolset progressively with other kits

Key Features

• Precision-machined forming die (matrix) for 6 mm CR pipes

• Conical half-shells (“pliers function”) for secure pipe clamping

• Protrusion gauge included to ensure correct pipe protrusion before forming

• Compatible only with Marbed 9376-D manual hydraulic press

• Stepped cone geometry optimized for common rail injection systems

Operational Functions

• Nipple forming (pipe end flaring) of 6 mm CR diesel pipes

• Vertical installation in the 9376-D press with retaining ring

• Stepped cone forming ensures sealing integrity at extreme pressures

• Conical retaining system guarantees precise alignment under vertical press load

Technical Data

• Pipe outer diameter: 6 mm

• Pipe wall thickness: not critical – the press adapts to different thicknesses

• Pipe hardness: high (common rail pipes are rigid, cannot be bent easily by hand)

• Profile: stepped cone, specific to common rail systems

• Compatible press: Marbed 9376-D (20-ton manual hydraulic press)

• Supplied tools: forming die, conical half-shells, protrusion gauge

Use Cases

• Common rail diesel vehicles and engines

• Workshop CR pipe repairs

• Mobile service vans for onsite interventions

• Stationary engines and generator maintenance with CR systems

Kit Contents

• 1 forming die (matrix) for 6 mm CR pipes

• 1 set of conical half-shells (“pliers function”)

• 1 protrusion gauge

⚠️ Note: the retaining ring required to lock the half-shells is supplied with the 9376-D press. It is an integral, non-removable part of the press and not included in the kit.
