Seal Faces

Carbon & Graphite Components

Carbon graphite’s real advantage isn’t any single property — it’s that it’s self-lubricating, dimensionally stable under heat, and chemically inert all at once, which is why it shows up in so many different rotating and reciprocating applications where oil or grease lubrication isn’t practical or permitted. Mech Seal Engineering manufactures a full range of carbon graphite components: Carbon Bush Bearings and Thrust Discs & Bearings for self-lubricating radial and axial load support, Carbon Seal Rings and Segment Rings for shaft sealing in pumps and compressors, Carbon Rotary Joints for steam and heat-transfer fluid transfer between stationary and rotating equipment, Thrust Pads for axial bearing support in heavy machinery, and Piston Packing & Turbine Rings for reciprocating and rotating equipment running at temperatures where elastomer seals would fail. Each component is machined to your OEM drawing or original part dimensions.

MG1 Carbon Mechanical Seal Face

Carbon seal faces are prized for their natural self-lubricating properties, low friction coefficient, and excellent thermal shock resistance. They run cooler against harder mating faces like ceramic or silicon carbide, making them a dependable, cost-effective choice across a wide range of general industrial fluids.

This carbon seal face is precision-lapped to match the MG1 seal's exact dimensional specification, fitting directly into existing MG1 assemblies as a standard replacement wear part. We supply resin and antimony-impregnated carbon grades suited to water, general chemical, and standard industrial pump service.
