The treated carbon-graphite is suitable for spherical sealings; the seal is perfect and maintenance is quick and easy. Available in the sizes ranging from ¼” to 2” 1/2.

Self-support by means of two graphite bearings amply spaced out. Seal ring is made of impregnated graphite and works in compression (the compression strength of graphite is approx 5 times greater than the corresponding tension strength).
