Highfield’s Locking Pipe Plugs and Caps are economical solutions to open-ended piping problems for water and gas utilities. Two-piece construction allows the outer shroud to rotate freely around the inner plug, eliminating unauthorized removal. Our high security locking plugs and caps install easily and are available in standard pipe sizes from ½” to 2” NPT, male or female thread.
Our pipe locking plugs are made entirely of case hardened steel with corrosion resistant plating for a long service life in the field. An O-ring seal mounted on the plug or cap protects against adhesive fouling. Regular profile high security locking plugs have optional sealing slots where you can add lead wire or padlock seals for further protection against tampering.
Low profile high security locking plugs offer additional benefits:
For both regular and low-profile lock plugs: once installed and locked into position the shroud will rotate freely, eliminating unauthorized removal.
Highfield also offers standard security locking pipe pugs and caps. Contact our team with questions about locking pipe plugs for water and gas service lines, or request a quote today:
