Zafety Flange Locks™

Zafety Flange Locks™ were developed to assist in the securing of nuts on flanges for any type of pipeline or pipe installation requiring the flanges to be connected using a nut and bolt system. Zafety Flange Locks™ are installed over two adjacent nuts, creating resistance between the nuts to minimize their ability to rotate and prevent them from loosening and allowing the flange ends to become separated. Reducing the risk of flange connection leakage.
