The oil press DIN 71412 A (lubricating nipple) meets the GOST 19853-74 standard, has a straight shape H1 (180) with a turnkey hexagonal drive and a metric or inch thread pitch.
The oil press DIN 71412 is equipped, on the one hand, with a thread (of different diameters) of a conical shape, for tighter screwing into the part and elimination of leakage, and on the other hand, with an opening for supplying lubricant with a special syringe (lever or rod).
For the manufacture of DIN 71412 oil presses, zinc-coated steel, copper, brass, and A1 grade stainless steel are used; A4-70; A4-80. This makes it possible to use the oil press in places with high humidity and moisture.
The minimum possibility of using pressed oil is 2 thousand cycles. You can find out information about availability, delivery terms, size series at the Eurobolt Ukraine office at no. tel.
