Hello Anyone, Could you help me in finding the torque req. for a cap to leak proof? My cap (polyproplene) which dia. was 32mm and its detail specs are, thread major dia.- 28.5mm, min. dia. - 26mm, pitch - 3mm, thread angle-45deg which has a EPDM rubber seal placed inside (outer dia 26.5mm & inner dia-18.5mm with thick 1.5mm) I want to know.. what should be the torque required to tighten the cap, so that It will be leak proof? or in other way what is the % of seal compression req. for leak proof? to handle the water pressure of ~600N in a plastic container.
