Silicon Carbide Seal Ring

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Seal Ring.


Silicon Carbide Seal Ring, SiC Seal Ring

Silicon carbide (SiC) has excellent thermal conductivity, corrosion resistance, and low thermal expansion. Silicon carbide is an excellent material for sealing rings and bearings. Silicon carbide seal rings have excellent corrosion resistance, great wear resistance, and great mechanical strength under high temperatures. We supply many sizes of silicon carbide seal ring as well as other SiC products.
