NBR Lip Seal

The NBR Lip Seal Ezfitt (Reference: 514) represents excellence in sealing for Express heavy duty fittings. This precision technical component, compliant with the rigorous French standard NF E29-573, guarantees perfect sealing in the most demanding connection systems.

Versatile applications and guaranteed performance

This professional lip seal excels in multiple industrial environments. Its compatibility with water, air and oils makes it a preferred choice for hydraulic, pneumatic and cooling systems. Professionals adopt it for:

Industrial water treatment installations, where its chemical resistance ensures remarkable longevity. Workshop and factory pneumatic circuits benefit from its reliable sealing even under variable pressure. In mobile hydraulic systems, this seal maintains its performance despite vibrations and mechanical stress.

Its operating temperature range of -10°C to +70°C covers the majority of common industrial applications, from cold storage room environments to machine tool cooling circuits.

NBR technology and regulatory compliance

The nitrile-butadiene rubber (NBR) constituting this seal offers exceptional properties of elasticity and chemical resistance. This technical raw material, selected by Ezfitt, guarantees excellent resistance to hydrocarbons and industrial fluids.

Compliance with standard NF E29-573 certifies that this seal meets the strictest requirements of French industry. This standard specifies the dimensions, tolerances and performance required for sealing elements in Express heavy duty fittings.

The lip design optimizes contact with sealing surfaces, creating an effective barrier against leaks even under low pressure. The studied lip profile ensures homogeneous contact over the entire circumference, eliminating weak points.

Optimized installation and maintenance

Installing this lip seal requires no specialized tools. Its flexibility facilitates placement in Express fitting grooves, while its resistance prevents tears during assembly.

Before installation, check the cleanliness of contact surfaces and absence of scratches on sealing seats. Light greasing compatible with the fluid used facilitates assembly and improves initial sealing.

Preventive maintenance consists of periodically checking the seal condition during disassembly operations. Its color and flexibility provide information on its aging state. A hardened or cracked seal must be replaced immediately.

To extend its service life, avoid sudden overpressures and respect the specified temperature range. Storage in a dry environment, away from direct light, preserves its elastomeric properties.
