Böllhoff Seal Lock® Seal Nuts

Böllhoff’s SEAL LOCK® sealing nuts provide a reliable seal against unwanted leaking of gaseous or liquid media. The SEAL LOCK® ring integrated on the nut helps to achieve reliable sealing inside the thread without the use of additional elements. It is reliable in two ways because it seals under the head and inside the thread. Not to mention the easy installation.
