Rice Lockable J Plugs
The “J” Plug is an expandable pressure plug developed to fit inside a flush threaded riser or casing. When the wing bolt is turned, the “O” rings depress and expand to create a watertight seal helping to ensure against any contaminates leaking into the well.
The “J” Plug consists of mold injected PVC housing with a PVC wing bolt. A black laminated triangle with the words “NO FILL ” is located on the top of the PVC wing bolt in accordance with API’s Recommended Practice 1615. For additional safety, “ MONITORING WELL – NO FILL” is molded on the top of the “J” Plug in raised letters.
