Silicon Carbide (SiC) Seal Ring
Silicon carbide (SiC) is a has excellent thermal conductivity, corrosion resistance, and with 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, great mechanical strength under high temperatures. We supply many sizes of silicon carbide rings as well as other SiC products.
