Sealing systems built for extreme oilfield conditions

The oil and gas industry spans drilling, completion, production, and processing, with equipment exposed to high pressure, elevated temperature, aggressive produced fluids, and long service intervals between interventions.

Oil & Gas Solutions

Moss Seal supports this equipment with sealing products engineered for pressure containment, extrusion resistance, rapid gas decompression, and abrasive or sour media, specified against the actual well environment rather than a general-purpose catalogue compound.

Sealing

Field Operations

Sealing points run from wellhead equipment and BOP systems through downhole drilling tools, completion assemblies, and production pumps, each with its own combination of pressure, motion, temperature, and chemical exposure.

Pressure control

Wellhead and BOP equipment demand high-pressure static and dynamic sealing across valves, hangers, connectors, and ram assemblies. Profiles and back-up systems are specified to contain pressure and resist extrusion during emergency operation.


Downhole and completion

Drilling tools and completion hardware see vibration, abrasive media, pressure cycling, and elevated temperature. Packers, plugs, and sleeves rely on elements that isolate reliably and survive repeated setting cycles.



Production and processing

Reciprocating and rotating equipment handling produced fluids and gas needs wear-resistant sealing. Compounds are qualified for sour service and rapid gas decompression so seals do not blister or fail on pressure let-down.
