Our Carbon And Graphite Gland Seal Ring also referred as Contact Seals & Contact free grooved split Seals. Contact Seals are multi segmented seal rings used for rotating shafts and linear motion pistons. The sealing effect is obtained with springs that easily press the carbon segments to the sealed surface. Contact Seals consistently rub against a counter face materials and therefore are subject to mechanical wear and tear. Carbon And Graphite Gland Seal Ring is designed as single part or multi-segment rings, which need a perfectly defined clearance to the sealed shaft.
