Accessories for Pneumatic Spearguns
This category includes all the accessories and spare parts needed for rigging, maintenance, and customization of pneumatic spearguns for spearfishing. The products available cover the most common needs among spearfishers who use this type of speargun: from replacing worn components to adding functional accessories such as vacuum muzzles, pressure gauges, and mounting systems for action cams.
Product Types
Vacuum Muzzles
The muzzle is the front end of the pneumatic speargun barrel, the point from which the shaft is expelled when fired. In the standard configuration, the barrel floods with water during loading: this means that, when fired, the piston must push and expel both the shaft and the water inside the barrel, resulting in energy loss.
Vacuum muzzles are designed with a seal system that prevents water from entering the barrel during loading, keeping the inner barrel dry. This way, when fired, the piston only has to expel the shaft, converting a greater share of the stored pressure into shaft exit speed at the same operating pressure in the reservoir. The shock-absorbing bushing in the muzzle also helps reduce noise generated during the shot. The vacuum muzzles available in this category include the X-Power system by STC Italia, which uses a dynamic seal that opens under the effect of piston pressure, allowing the shaft to exit without limiting its travel and supporting staged loading, and the Salvimar lightweight aluminum muzzle, consisting of a wishbone, sealing gasket, body, and high-strength shock-absorbing bushing, available for 11, 11 EVO, and 13 mm barrels and compatible with bushings for 7.0 and 8.0 mm shafts.
Installing a vacuum muzzle requires a preliminary compatibility check with your speargun, especially regarding the barrel diameter and the diameter of the shaft used, since the shock-absorbing bushings are sized for specific measurements.
Replacement Pistons
The piston is the component that, driven by the compressed air pressure contained in the reservoir, transfers kinetic energy to the shaft when fired. Over time, the piston seal can deteriorate, causing internal pressure leaks and a reduction in shooting power. The replacement pistons available in this category are compatible with 11 and 13 mm barrels and are intended for the most popular models on the market, including Cressi, Mares, and Salvimar spearguns.
Pressure Gauges
The pressure gauge is a tool that screws onto the charging valve of the pneumatic speargun and allows you to read the internal pressure of the reservoir. This accessory is useful both during initial pressurization, to set the desired working pressure between the typically used 15 and 30 bar, and during routine maintenance, to check for leaks. The pressure gauges available are specific to speargun models from different manufacturers, including Mares, Cressi, and Salvimar.
Line Slides
The line slide is the component mounted on the pneumatic speargun shaft that connects the shooting line or cord to the speargun during the shot. The line slides in this category are made of glass-filled nylon and steel.
Lubricants for Pneumatic Spearguns
Internal lubricant is essential for proper pneumatic speargun function. The oil helps reduce piston friction against the inner barrel, preserve the integrity of the O-ring seals, and protect the internal metal components from oxidation in the marine environment. The lubricants available in this category, including Salvimar Green 32 oil, are specifically formulated for use in compressed-air spearguns, with low-viscosity characteristics and antioxidant properties.
Conclusion
Accessories for pneumatic spearguns are a range of technical components designed for the needs of those who practice spearfishing with this type of speargun. Proper selection and maintenance of these elements—muzzles, pistons, pressure gauges, loaders, lubricants, spare parts, and adapters—helps maintain the speargun’s performance over time and ensures full functionality during every spearfishing session.
Checking compatibility with your specific model—in terms of barrel diameter, reservoir diameter, and valve type—is the necessary starting point for every purchase.
