of female packing end 430 which is at about 130 degrees base 444 can have an angle of about 120 degrees packing ring 440 is preferably a u201c vee u201d packing ring u2014 comprised of bronze filled teflon such as that supplied by cdi material number 714 tip 442 of packing ring 440 is made at about 120 degrees which is blunter than the conventional 90 degree tips in an attempt to limit the braking effect e g caused by expansion of recessed area 434 of the female packing ring or end 430 which would cause side 433 of female packing ring to contact mandrel 40 on mandrel 40 when longitudinal force is applied through the packing base 444 being at about 120 degrees is believed to assist in causing packing ring 440 to bear against mandrel 40 and not side 433 of female packing ring 430 packing lubrication ring 450 preferably includes at least one rope seal such as a garlock u00bd inch or 7 16 inch or u215c inch 1 27 centimeters or 1 11 centimeters or 0 95 centimeters section 8913 rope seal rope seals have surprisingly been found to extend the life of other seals in the packing unit this is thought to be by secretion of lubricants such as graphite during use over time although shown in a u201c vee u201d type shape rope seals typically have a square cross section and form to the shape of the area to which they are confined here lubrication.
