Forming Kit – 8 mm Diesel Pipes

The Marbed 9376-DP8 forming kit is the dedicated solution for 8 mm diesel pipes, ensuring precise and repeatable pipe end forming. Unlike the 6 mm kits (DP6 / DP6CR), the DP8 kit is universal: the cone profile is the same whether the application is conventional or common rail.

Key Benefits

• Dedicated die kit for 8 mm diesel pipes

• Works on both conventional and common rail systems

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

• Conical retaining system ensures secure clamping and perfect tube positioning

• Ideal for heavy-duty diesel applications requiring larger pipe diameters

Key Features

• Precision-machined forming die (matrix) for 8 mm OD pipes

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

• Protrusion gauge included to ensure correct material protrusion

• Compatible only with Marbed 9376-D manual hydraulic press

• Universal cone geometry valid for all 8 mm applications

Operational Functions

• Pipe end flaring (nipple forming) of 8 mm diesel injection pipes

• Quick installation into the 9376-D press using the retaining ring

• Conical retaining system guarantees precise alignment and repeatability

• Standard cone profile suitable for both conventional and CR applications

Technical Data

• Pipe outer diameter: 8 mm

• Pipe wall thickness: not critical – the press adapts

• Pipe type: conventional and common rail diesel systems

• Profile: standard cone, universal for 8 mm lines

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

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

Use Cases

• Diesel trucks and heavy-duty vehicles

• Stationary diesel engines and generator sets

• Industrial pumping equipment

• Construction and earth-moving machinery

Kit Contents

• 1 forming die (matrix) for 8 mm diesel 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.
