Standard Security Lock Plugs & Caps

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.
