Performance Series - HP8 HIGH Pressure Piston (800-850psi)

Upgrade your HK Army Performance regulator with the HP8 (high pressure 800 psi) piston.

Enhance the performance of your regulator with this piston, equipped with a Belleville washer stack designed for precision and ease of use. This innovative component allows for quick and efficient adjustment of the output pressure without needing to purchase a completely new regulator unit. Simply remove the washer stack assembly and drop it into your regulator for optimal performance.

The robust brass piston, paired with a washer stack and necessary o-rings, ensures a leak-free experience. This stack is also a great solution for those facing worn piston systems that no longer provide consistent output pressure.

Features :

• Low-pressure output : The washer stack is pre-set to adjust the regulator's output pressure to 800-850 psi.
• Belleville washer block : These washers (or disc springs) provide significant force in a compact space, allowing for a more streamlined and lightweight design compared to traditional coil springs.
• Quick and efficient swap : The washer stack unit can be easily removed and replaced.
• Brass piston : Durable construction with necessary o-rings for leak-free performance.
• Constant output pressure : Ideal for replacing worn pistons and restoring regulator performance.
• Compatibility : Specifically designed for HK Army Performance series regulators.

Caution : Make sure the air system is fully degassed before performing any regulator updates to avoid injury or damage.
