Primeline MICRO 1.6mm ID

Exclusively made for C4 by Primeline Industries, this new latex tubing features a fluorescent orange colour and it is available in 3 different dimensions.

Since 1982 Primeline Industries has produced the highest quality latex tubing for the spearfishing industry. Primeline has developed a unique latex tubing with unique properties that improve the performance of any spearguns and this 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 anti- oxidants 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.

14mm Small ID. The 14mm Small ID with 9/16” OD and 1,6mm/ 1,6mm ID hole is increasingly popular for multi-band applications, generating more power than Standard 1/8” hole rubber. Especially well suited for large blue water guns.
