TECHNICAL BULLETIN NUMBER 102 BREATHER ELEMENTS & ASSEMBLIES CUSTOM-ENGINEERED SOLUTIONS IN KNITTED WIRE MESH Metex Knitted Wire Mesh Products Solve Problems Cost Effectively Metex knitted wire mesh is manufactured from an “endless” wire that is formed into loops and subsequently networked, providing elasticity and resilience not found with woven wire or powdered metal products. The diversity and versatility of wire mesh enables Metex to produce products for a wide variety of applications, including: • Seals • Heat Wicks • Air Gap Rings • Breathers • Noise Attenuators • Filters • Coalescers • Mufflers • Shock Absorbers • Gaskets • Air Filters • Protective Coverings • Heat Shields • Electronic Shielding • Exhaust Seals • Navin Rings • Ball Joint Seal • Catalytic Converter • Catalytic Converter Systems End Rings Support Mesh • Flame Arrestors 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. Our Breather Elements & Assemblies continue a longstanding Metex tradition of integrating the right designs, materials, and manufacturing methods to meet customer needs for optimal performance at lowest possible cost.

Reducing such crankcase-emission carryover is not just a federal mandate with some types of engines—it’s also a key consumer concern. Metex has responded to the need for better control over such emissions with prolonged-life, knitted wire mesh breather elements and assemblies. Metex products help dramatically reduce the escape of crankcase emissions from such engine sources as: • Condensation of crankcase aerosol • Mechanical shearing from valve springs and other mechanical parts • Lubricating oil that exits the engine through the crankcase breather tube or assembly Metex designed and manufactured Breather Elements and Assemblies provide long-lasting performance in reducing crankcase emissions as well as oil consumption and oil pooling on external engine and vehicle parts— while protecting air-intake products in closed-crankcase ventilation (CCV) systems. Engine manufacturers have also found that Metex Breather Elements and Assemblies provide a greater degree of market differentiation among an increasingly environmentally conscious buying public—helping to improve customer loyalty for specific engine brands.
