The Snowpulse cylinder is reusable. However, when it has been blown, before filling it with dry compressed air to 3000psi, there is a small o-ring that must be changed. This o-ring is found on the piston which sits inside the top of the cylinder. The O-Ring Kit provides everything you need to change the O-Ring yourself: 10 O-Rings, tweezers, red tape to protect the cylinder from moisture, grease to ensure proper workings of the mechanical parts of the cylinder and an extra pin. The O-Ring Kit is a must if you plan to be refilling the cylinder yourself and not with an established Snowpulse Refilling Station.

Kit available in 10 or 20 uses
