CUSTOM-ENGINEERED
SOLUTIONS IN
KNITTED WIRE MESH

For forty years, Metex
design, development, and
manufacturing engineers have
been producing engineered
components that take maximum advantage of the
unique characteristics and
robust nature of knitted wire
mesh. Its interlocked looped
structure, which offers excellent resiliency, memory—
even when subjected to
high temperatures as well
as high-tensile or compressive stress—and strength,
make knitted wire the ideal
choice in materials when
both performance and cost
are paramount.
Metex products now
meet a wide range of critical
needs—from providing flexible, yet durable, seals and
joints to noise attenuation,
thermal insulation, and filtration—in some of the most
demanding industrial applications and environments.

High-Temperature Flange Gasket with
Integral Heat Shield for Thermal Protection
Of Sensitive Components
The Metex Ring Gasket with Heat Shield represents the next evolution in our
all-metal gasket technology by bringing together the unique, zero-leak performance characteristics of our knitted wire mesh flange gaskets with built-in
heat protection in a single, all-metal gasket assembly.
The result is optimal thermal protection for sensitive automotive components such as on-board computer sensors—all with greater ease of installation
and overall system integrity. Combining the gasket and heat shield in one
integrated unit offers a number of significant advantages in automotive manufacturing:
• Simplified Assembly—with greater speed and ease of assembly, our
unique single piece gasket/shield design eliminates the need to bolt, weld
or strap the heat shield in place.
• Reduced acquisition costs—The unit not only cuts labor and component costs but reduces inventory management by eliminating additional
part numbers.
• Cost-effective performance—zero leakage and thermal protection in
one product to protect sensitive automotive components.
As with our static flange gaskets (see Metex Technical Bulletin No. 109)
all gasket components are designed with a retention feature which ensures that
each unit remains in place during the assembly process. In addition, the
grooved static mating flange protects sealing elements from overcompression
and helps guarantee flange-to-flange contact.
Custom solutions to meet any sealing/thermal-protection need
Finite Element Analysis and CAD are used throughout the development
process to optimize design and functionality. Vibration and leak testing are also
conducted to ensure high-performance, leak-free joints.
Metex offers more than four decades of technical expertise in developing
high-temperature spherical seals and gaskets for customers worldwide. We can
custom design a high-integrity, temperature-resistant gasketing system using a
variety of different shapes and metal alloys to meet
your specific requirements.
