Highfield’s Locking Plugs and Caps for water and gas lines have been engineered to permanently lock off open pipe ends, for service cleanouts, discontinued service and more. When installed and locked in place, the hex head rotates freely to prevent unauthorized removal. Our locking pipe plugs and caps are available in ½” to 2” NPT with male or female threads.
Standard security plug locks and caps are manufactured entirely from case hardened steel with corrosion resistant plating for a long service life, and compatible with the #4 barrel lock key.
Highfield also offers high security locking pipe plugs and caps. Contact our team with questions about line caps or plugs for water and gas utilities, or request a quote today:
