This is an Aqua Lung Sintered Brass 1st stage Filter #105106 with SS Ring Spacer #124628
If you remove a vintage filter you will notice that it is encapsulated by a band that goes around the outer edge and is crimped in. The spacer ring will provide almost the same thickness.
Please install correctly; filter sits on top of the spring, then the filter ring and the C-Clip with the "sharp" edge of clip facing up.
*Always have your equipment serviced by a professional regulator technician. Improper assembly, or using wrong parts may lead to serious injury or death.
