The Type GL1B is a double-ply formed bellows seal to meet the dimensional requirements of DIN 24960 L 1K. The double-ply design results in axial-flexible, yet extremely strong construction. The GL1B is used on general sealing duties in pumps, mixers, blenders, agitators, compressors and other rotary shaft equipment. The bellows are manufactured from Inconel 625 for strength and corrosion resistance, and face materials for arduous service are available.
