Aluminum B Size Particulate Filters

(2 customer reviews)

The link below is our selection guide that will assist you in selecting your filter:

Our B Size Filters are smaller and lighter than the D Size and are more suitable for use with pistols. We believe that our design results in the most versatile and easy to use Solvent Filter on the market.

OAL = 6.86″ / OD = 1.26″

The 1/4″ and 3/8″ filters come with a 1/2-28 threaded end cap to directly attach to a compatible barrel thread. An adapter is required (not included) to direct mount the 7/16″ and M10 filters.

    These solvent trap filters are by FAR the best i have ever used. The quality and craftsmanship are unmatched. The filters and caps are precisely machined to fit perfectly and the screen filters catch everything that you don’t want to recycle. This is the STANDARD for solvent traps and filters.

    Great product and machining. Does not perform as well as I had hoped. I don’t know if it’s because it’s aluminum or if the cups need a redesign. Using with savage 22lr
