Exclusively made for C4 by Primeline Industries, this new latex tubing features a fl uorescent orange colour and it is available in 3 diff erent dimensions.
Since 1982 Primeline Industries has produced the highest quality latex tubing for the spearfi shing industry. Primeline has developed a unique latex tubing with unique properties that improve the performance of spearguns and its quality is recognised unanimously around the world.
The latex raw material is a milky substance extracted from plants principally the Hevea Brasiliensis. Unlike other producers Primeline doesn’t dry the substance prior to working it thereby not breaking the polymer chain. The outcome is a more elastic rubber with higher resistance to tear.
Primeline’s unique physical properties are owed by the production process known as continuous dip which creates pure latex rubber in layer after layer. This long and laborious process creates a superior rubber. It produces a virtually protein free latex with more antioxidants than any other latex which it owes it’s long aging properties to. The 16mm speargun rubber developed for C4’s new STANDARD rubber is dipped 125 times whereas the Small ID 16mm is dipped 172 times.
After the initial “soak off ” which is a loss of stretch inherent in every rubber (9% for Primeline) the C4 Orangebull Standard looses less than 2% per hour.
