    PRODUCT DETAILS

    sd

    The GRIP-Z is a standard axial restrain coupling with reinforced internal structure so that can bear higher pressure. The double anchoring rings can bite into the two pipes and prevent them from pulling apart.  

    Suitable for pipes O.D φ30-φ168.3mm

    Suitable for pipes material: Carbon steel, stainless steel, copper, cunifer, cast and ductile iron, GRP, most plastic and other material.

    Pressure up to 64bar

    GRIP-Z is Reinforced coupling of GRIP-G. Have the same performance of GRIP-G and with higher pressure. Two anchor rings have progressive anchoring effect, it is easy on pipes, as pressure increased, so does the gripping effect. GRIP-Z offers high levels of security by locking pipes together under pressure. GRIP-Z working pressure up to 64 bar. Temperature range: -30℃ up to 180℃, material in SS304, SS316 and SS316TI. It suitable for most applications in building construction, civil engineering, power, machinery component, shipbuilding, offshore industries, industrial process pipe work and others.
