Cast‑in sleeves with an EPDM sealing collar are used where pipes pass through formwork and are cast into concrete. The flexible EPDM collar ensures reliable sealing against the formwork and allows minor movements during casting, supporting accurate and secure installation.
SIMONA Stadpipe manufactures the sleeves in black PE 100, providing high durability and chemical resistance. The solution suits applications where flexibility and sealing performance are critical and is commonly used in aquaculture and industrial installations.
