Choosing the right option
Choose the cord diameter to match the cross section of the O-ring or the groove. Cut the cord to the length of the groove centreline, allowing for the join, and join the ends with a suitable adhesive.
A joined cord seal is a repair or workshop solution. Where a standard size is available, a ready-made O-ring is under NBR 70 O-Ring, Metric, 3mm Cross Section, 3 to 150mm ID and NBR 70 O-Ring, Metric, 2mm Cross Section, 1 to 100mm ID. Cord is also offered in NBR 70 O-Ring Cord, Imperial, 1/16 to 1/2 in Diameter.
Check that the fluid and the operating conditions suit nitrile before fitting.
