Highfield’s Lock Seal Assemblies are cost-effective locking and sealing devices in a single unit.

They can be installed on a wing or wingless style gas meter connection nut with mating security hardware.

The lock seal provides positive protection against unauthorized use of gas as well as readily providing evidence of any tampering.

Components & Materials

Both the stud and lock seal head are made from case hardened steel with plating for corrosion protection.

Replacement seals are available in aluminum (silver color) for visual identification.

Lock seal heads are available in standard or tapered styles, with or without seals.

Studs are available in small diameter, regular diameter, and extra long regular diameter. We also provide a lock seal key, seal press and replacement seals.

How to Use
  • Installation
    • Simply snap the lock seal head onto the stud. The lock seal is now in the locked position.
  • Removal
    • Break the replacement seal by opening the tab and peeling away the replacement seal from the lock seal head.
    • Insert the lock seal key into the exposed lock seal head and separate the head from the stud. The lock seal is now in the unlocked position.
  • Resealing
    • Crimp the cement seal onto the lock seal head using the seal press. Repeat the installation procedure.
