C4 Orangebull elasticThe C4 Orangebull elastic it is latex supplied exclusively by Primeline Industries in the fluorescent orange color and with the “C4” brand.Since 1982, the leading American company in the sector has been producing extremely high quality natural latex. The company has developed for C4 a latex elastic with unique physical and mechanical characteristics, whose high qualities are unanimously recognized by the market.Primeline natural latex owes its extraordinary characteristics to the “continuous immersion” production process during which the latex is produced in layers.This is a very long and expensive process which however guarantees a superior quality product.The C4 Ø 16mm elastic with internal hole Ø 3.2mm is produced with 125 immersions while the same elastic with internal hole Ø 1.6mm is immersed 172 times. Following drying, called "soak off", the elastics generally lose their elasticity. The model developed for C4 has a loss of only 2%.Latex is virtually free of proteins, which cause allergies, and is also free of very polluting phthalates.The raw material of latex is a milk extracted from plants, mainly Hevea Brasiliensis. Primeline, unlike other manufacturers, does not dry the base material before processing (chewing) so as not to interrupt the polymer chains. The result is a latex tube that is more elastic and more resistant to cuts.Models AvailableOD (EXTERNAL DIAMETER) 14 mm ID (INNER HOLE DIAMETER) 1.6 mm: It is an extremely reactive and progressive diameter of elastic that is used on large blue fishing rifles.OD 16mm ID 1.6mm: It is the most powerful rifle elastic on the market. Thanks to an increased thickness it manages to combine power and reactivity. The result is immediate energy delivery without loss of modular strength. It is the ideal elastic for applications on rifles equipped with a single elastic or double elastic.OD 16mm ID 3.2mm: It is the most efficient elastic with the best ratio between load force and power delivered. Suitable for single elastic rifles and ideal for rifles with double elastic.– DIRECTIONS for making a circular elastic band:Take the measure L on your speargun.L = from the notch or from the pin on which the wishbone is to be placed to the seat of the elastic in the muzzle.14mm elastic bands: (L cm x 2 ) / 3.416mm elastic bands: (L cm x 2 ) / 3.2/3.3ger the cm necessary for the ligatures.Example: suppose L is 80cm and you need to prepare a 16mm elastic :80cm x2 = 160cm160 : 3.3 = 48.48cm48.48 3 cm ( cm for standard bindings) = 51.48 cm– DIRECTIONS for making a single elastic:Take the measure L on your speargun.L = from the notch or from the pin on which the wishbone is to be placed to the seat of the elastic in the muzzle.14mm elastic: L cm / 3.416mm elastic: L cm / 3.2/3.3add the cm needed for the bindings.Example: suppose L is 80cm and you need to prepare a 16mm elastic :80cm : 3.3 = 24.24cm24.24 3 cm (cm for standard bindings) = 27.24 cmI will then need to cut a 16mm elastic 27.24cm long.
