Self-seal

Sealtek® SELF-SEAL is a self-polymerizing tape made of siliconic rubber, suitable for immediate application before Sealtek® SEAL-TEX being used. Wrapping the tape around the leaking pipe will allow an easier and quicker repair operation, thanks to its self-conglomerating properties. To seal large holes a wooden wedge or a screw can be employed, together with Sealtek® SELF-SEAL.

Available sizes: 5m x 25mm; 5m x 50mm.
