Maloney Oil Well Cementing Plugs

Rubber Body Cementing Plugs

Maloney cementing plugs are the most widely used plugs in the world. They are specially designed with a positive wiping action to insure clean casing. All rubber components are compounded and manufactured by Maloney to maintain high precision standards. Plugs are available in a wide variety of sizes and stocked for immediate shipment. To order, just specify part number(s) listed on charts. Special sizes available on request.

Top Plugs

The bottom section of the cup is designed to exert continuous pressure on the casing wall. The core is made of a glass-filled high strength phenolic resin core. The tapered base fits the cavity of the bottom plug for a positive seal. A solid rubber top plug is available on request.

Bottom Plugs

Like the top plug, the fins and tail section provide positive wiping action. Fins also serve as a seal while cementing. They are specially designed with a glass-filled high strength phenolic resin core. A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.
