Greybull Band 16 Mm 3.2 Mm

Exclusively made for C4 by Primeline In- dustries, this new latex tubing features a fluorescent orange colour and it is availa- ble in 3 different dimensions.

Since 1982 Primeline Industries has pro- duced the highest quality latex tubing for the spearfishing industry.

Primeline has developed a unique latex tubing with unique properties that improve the perfor- mance 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 He- vea Brasiliensis.

Unlike other producers Primeline doesn´t dry the substance pri- or 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 proper- ties are owned by the production process known as continuous dip which creates pure latex rubber in layer after layer.

This long and laborious process creates a supe- rior 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 16mmisdipped172times.

Aftertheinitial “soak off´´ which is a loss of stretch inher- ent in every rubber (9% for Primeline) the C4 Orangebull Standard loses less than 2% per hour.

These are the diameters in which the tubing is available and they are.

GREY BULL 16 MM / 1,6 delivered in rolls of 15mt.

16mm Standard Outside Diameter.

5/8´´ OD with a 3,2mm / 1/8´´ ID hole this rub- ber has the most reliable and renown ad- vantages of pull effort and power.

This thickness is an ever popular standard of the speargun industry.

Combines all the advantages of power, pull effort to 350% and Primeline´s properties.

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.

16mm Small ID.

The 16mm Small ID with a 5/8´´ OD and 1,6mm ID hole is the most powerful 16mm rubber on the market.

It combines the punch and power of 16mm rubber with the extra volume in the rubber to produce more energy without losing any of its high modulus characteristics.

Ideal for single and double band applications.
