    Explosion-proof nipples of the HVN series

    Explosion-proof nipples of the HVN series

    Product Description

    NVN are explosion-proof nipples designed to connect pipe components of the same diameter in hazardous areas. They ensure leak-proof and reliable connections during installation in challenging conditions.

    Advantages

    • Reliability and durability - the wall thickness is adapted to prevent mechanical damage during installation of the pipe line
    • A variety of materials and sizes are available: nickel-plated brass (resistant to H2S, acids, and salt fog), stainless steel (AISI 304), and galvanized steel; threads are available in metric, inch, or pipe sizes; various climatic versions are available
