Formwork accessory

CORKSEAL T­21 is a special sealing closure device for tubular formwork spacers, consisting of a rigid core made of polyamide plastic material and a corrugated cap in hydro-expansive rubber. The core of CORKSEAL T­21 is provided with special circular lamellas that surround it and that, if properly inserted into the spacer, provide a high pressure mechanical seal, so that the sealing element is not removed from the seat where it is placed even in the presence of negative thrust. CORKSEAL T­21's hydro-expansive cap is designed to ensure the hermetic sealing of the internal part of the tubular spacer.
