Fitting seal JR series

O-ringcircularNBR

The profile seal Techné DIN 3869, also known as a connection seal, has a simple shape that allows for quick and easy assembly. Unlike an O-ring, the profile seal DIN 3869 does not twist in its groove and does not deform, even under pressure. Its dimensions comply with the DIN 3869 and DIN 3852 standards for groove and thread dimensions, as well as the European standards ISO 9974-2:2000 and ISO 1179-2:2008. The JR fitting seal can withstand pressures up to 600 bar. Main applications The profile seals DIN 3869 is used in hydraulic connections and plugs. Its applications are wide-ranging and include connections for agricultural machinery, construction equipment, heavy-duty vehicles, automobiles, and more. Materials NBR 85±5 IRHD (black) FKM 80±5 IRHD (green) EPDM 85±5 IRHD (purple) Techné can provide other materials on demand (HNBR, FFKM, compounds with food or drinking water approvals, low-temperature NBR compounds, etc.). Specific dimensions can be achieved through machining. Coatings To reduce assembly efforts and improve production line efficiency, Techné offers surface coatings tailored to the profile seal.
