If you hear that psssshhh noise from your VS reg, it's probably coming from the vicinity of the on/off knob. Seems someone's always either overpressurizing the reg or using C02 and bustin pressure right through those poor little O's. Well, we've got the replacements for you and made it even more convenient including all you'll need in this neat little kit. The kit includes both on/off knob o-rings and the c-clip that holds the knob onto the regulator. As usual, SPPS has the parts you need and these are all included in a convenient kit form.

This kit includes: parts #ITP008 c-clip, #ORG18 o-ring and #ORG13 o-ring.
