The Nu-Tech Square Nylon Tube Insert (Part A020/024) is an M8 threaded anti-vibration levelling component featuring a nylon body with nickel-plated brass bush, rated for 1000kg static load capacity. It is installed into equipment feet or mounting points to isolate vibration and provide adjustable levelling. Critical verification: confirm the 1000kg load rating is per insert or total system capacity, and validate nylon material compatibility with operating environment temperature and chemicals.
