Exhaust Manifold Gasket - 68x68x2 mm, bore 40 mm - code: 0000051 - Fischer Panda

Fischer Panda exhaust manifold gasket code 0000051

The gasket for exhaust manifold Fischer Panda code 0000051 (also indicated as 000051) is a spare part dedicated to sealing between exhaust manifold flange and exhaust riser. It is designed for applications in the nautical field and onboard systems, where sealing continuity and long-term stability depend on a proper mating between surfaces and a component suitable for the typical conditions of the exhaust circuit.

The size is 68 x 68 x 2 mm with inner hole of 40 mm: useful data to verify compatibility with the existing flange before ordering, especially in case of maintenance on already installed systems or with a history of different spare parts.

Features and details

Code and identification

• Manufacturer / supplier: Fischer Panda
• Supplier product code: 0000051 (also written as 000051)

Application

The gasket is intended for the’exhaust manifold flange / exhaust riser coupling. In this position, the gasket works as an interface element between two metal components, helping to maintain gas passage sealing and manage micro-irregularities of the contact surfaces.

Dimensions

• External dimensions: 68 mm x 68 mm (square/diamond profile depending on hole spacing)
• Inner hole diameter (gas passage): 40 mm
• Nominal thickness: 2 mm

Construction material

The gasket is made of reinforced composite (lamellar graphite or asbestos-free aramid fibers) with internal core of perforated steel / metal cage. This structure is typical of gaskets used on exhaust joints, where it is useful to combine the adaptability of the composite with the mechanical support of a metal reinforcement.

Operating thermal resistance (declared data)

Operating thermal resistance indicated as constant up to 700°C – 800°C (with short-term peaks higher).

Why thickness and structure are important

In the collector/riser area, the gasket is exposed to typical exhaust conditions: thermal variations, vibrations, and stresses related to engine operation. In this context, two aspects become central:

• Mechanical support: the’metal core helps maintain the stability of the gasket during tightening and operation, reducing the risk of unwanted deformation of the composite material alone.
• Adaptation to the coupling: the 2 mm thickness provides a useful margin to compensate for micro-irregularities and small settling of the flanged joint, maintaining an effective contact surface.

During maintenance, these elements help to choose a replacement consistent with the original, avoiding “similar” substitutions only by size but not by structure.

Applications (Fischer Panda generators)

This gasket with 40 mm hole is indicated as used on Fischer Panda generators equipped with compact diesel engines, including:

• Compact series models: Panda 4000S, , Panda 4500, , Panda 4200
• iSeries models (inverter): Panda 5000i, , Panda 5000i Neo
• DC charging systems: specific versions of the range AGT 4000

Note: in case of installation variants or updates over time, it is good practice to check the code 0000051 and the dimensions 68 x 68 x 2 mm with 40 mm hole before replacement.

Operational advantages

• Spare identifiable with Fischer Panda code: useful for scheduled maintenance and proper spare parts management.
• Clear format for quick verification: external dimensions and internal hole allow immediate control of geometric compatibility.
• Reinforced composite structure: solution suitable for exhaust joints where thermal cycles and vibrations are present.
• Nominal thickness 2 mm: indicated for flanged couplings where an element with settling capacity is useful.

Usage and installation notes

Pre-assembly checks

• Check that the code matches the required one (0000051 / 000051).
• Check dimensions and internal hole (68 x 68 x 2 mm, 40 mm hole) compared to the flange.
• Inspect the contact surfaces of the manifold and riser: any marks, residues or irregularities may affect the seal.

During replacement

• Place the gasket correctly between the surfaces, ensuring that the 40 mm hole is centered on the gas passage.
• Tighten according to the procedures provided by the system/assembly, avoiding unnecessary forcing.

When it is advisable to replace it

Replacement is typically recommended during interventions on the manifold/riser or when performing maintenance on the exhaust assembly. In general, a gasket that has been removed may not guarantee the same fit upon reassembly: for this reason, in maintenance contexts, it is often preferred to install a new and properly identified spare part.

Summary

Fischer Panda exhaust manifold gasket with dimensions 68 x 68 x 2 mm, 40 mm hole, code 0000051: dedicated spare part for manifold/riser flange, with reinforced composite structure and metal core.
