AS5220PT

The Autosealer® 5220 is a compact, cost-effective ammunition waterproofing and sealing system. The Autosealer® 5220 is ideal for smaller production environments, qualifying runs (first article) or testing labs. The manually loaded 5220 dispenses Hernon® ammunition sealants on ammunition primers and casemouths via Sureshot® precision dispensing valves and then cures the sealant in seconds with powerful Ultracure® UV LED curing lamps - leaving the rounds completely waterproof and ready for immediate use or packaging.

Sureshot 3510

The Sureshot® 3510 precision dispensing valve accurately controls the application of low viscosity fluids. The 3510 valve provides repeatable precision micro-dispensing with a cycle rate of over 500/min. Users can adjust the fluid flow by changing pressure control. Two needles are available for use with the 3510 valves with orifice dimensions of 0.01? and 0.007?. Easily fix a bent or cured tip by replacing the stainless steel dispensing needles. Simply unscrew the damaged or clogged needle and screw in the replacement. With a small size and low weight, the valve can be placed into narrow fittings and is a match for retrofitting. The 3510 replaces the 3500 valve previously offered.
