Profile seal DIN 3869



Profile sealing rings acc. to DIN 3869 are used as axially static soft seals in combination with threaded elements,
e.g. in construction machinery,hydraulic presses, injection machines,fittings, hydraulic valves and threaded tube connections in industry in general.



Function

DIN 3869 profile sealing rings are used for the axial-static sealing of threaded tube connections, fittings and sealing screws with stud ends in con￾nection with ports. By tightening the
screw connection the easy-to-handle elastomer profile sealing ring is com￾pacted, thereby producing the sealing effect at the surfaces to be sealed. The purpose of the profile sealing ring is
to stop the medium from leaking, thereby preventing loss of pressure. The geometry protects the seal against twisting during installation and in the installation housing. At the same time,
the profile sealing ring holds back dust and dirt. Any mechanical defor￾mation of the cross-section is min￾imised due to the geometry of the profile.
