Progressive Pressure-Assisted Hydraulic Gasket
HYMAX dual sealing - HYMAX products feature mechanical sealing, similar to other products, which is achieved with the bolt closing mechanism, In addition, HYMAX® achieves hydraulic sealing using its progressive hydraulically-assisted gasket which self-inflates using flowing water pressure. The patented gasket self-inflates under rising water pressure conditions and exerts more pressure on the sealed pipe to maintain a perfect seal.
