PRODUCT DESCRIPTION

DIN 3869 profile sealing rings are used for the axial-static sealing of threaded tube connections, fittings and sealing screws with stud ends in connection with ports. By tightening the screw connection the easy-to-handle elastomer profile sealing ring is compacted, 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 deformation of the cross-section is minimised due to the geometry of the profile.

PRODUCT ADVANTAGES

• Seals can be refitted
• Low mechanical deformation of the cross-section under pressure loads
• Seals do not twist in the groove 
• Simple to handle when fitting
• Low sensitivity to gap extrusion
• No relative movement in the groove at pressure pulsation
• Slight leakage also with low-viscosity mediums
• Minimal cross-section deformation
