Key Features & Benefits at a Glance
- Superior sealing performance with Buna-N rubber that maintains integrity under 6400 psi fluid and 200 psi gas pressures
- Exceptional temperature resistance from -10°F to 240°F for reliable operation in extreme environments
- Enhanced corrosion protection through zinc-plated steel construction extending service life in harsh conditions
- Optimized mechanical strength with Rockwell B105 hardness ensuring dimensional stability under load
- Precision M3 compatibility with 2.7mm ID and 6mm OD for perfect fit and uniform load distribution
- Durable rubber-to-metal bond that prevents seal displacement during installation and operation
- Consistent sealing performance maintained by Durometer 60A rubber hardness across the operational temperature range
Professional Applications & Engineering Value
These metal bonded washers provide critical sealing solutions where standard washers fail. The zinc-plated steel base offers structural integrity while the Buna-N rubber seal creates an impermeable barrier against fluids and gases. Engineered for industrial applications involving hydraulic systems, pneumatic equipment, and machinery requiring reliable pressure containment. The bonded construction eliminates the risk of seal separation during vibration or pressure cycling, making these metric washers ideal for automotive, manufacturing, and fluid handling systems where high-pressure resistance and temperature stability are paramount. The precise M3 sizing ensures proper installation without compromising the sealing surface.
Specification Summary & Compliance
Manufactured to precise metric dimensions with 2.7mm ID, 6mm OD, and 0.9-1.1mm thickness tolerance. The zinc-plated steel construction meets industry standards for corrosion resistance while the Buna-N rubber complies with material specifications for oil and chemical resistance. Mechanical properties include Rockwell B105 hardness for the steel component and Durometer 60A for the rubber seal. Rated for continuous operation from -10°F to 240°F with maximum pressure ratings of 6400 psi for fluids and 200 psi for gases. Complies with RoHS and REACH environmental standards for industrial applications.
