Speedfit pipe insert should always be used with Speedfit pipe. The Superseal insert contains two 'o' rings to provide even greater sealing security than a standard insert.
- Superseal Inserts should be used with Speedfit pipe and fittings to enhance the seal
- Inserts must be used on all Speedfit connections (when connecting to a Compression fitting, standard TSM inserts must be used)
- Suitable for hot and cold water and central heating system
