7" Tube & End caps: Premium


This includes only the 7" tube and two endcaps (one attachment cap, one solid end cap). Internal filter cups and fitting is not included. 

Tube: 7-inch Black anodized tube made from 6061-T6 Aluminum with 2.5mm thick sidewalls to withstand heavy stress. T6 treatment= heat to 932 degrees hot + then rapid cool + then heat to 390 degrees for two hours = damn tough metal. The tube OD is 43mm, ID is 38mm.

  • Attachment cap: with 13/16" center hole. 18mm (3/4”) super-thick aluminum. 6061-T6 anodized black. Takes any 13/16 fitting, fast attach, flash hider, or concussion forwarder, as long as they are 13/16" by 16 tpi (threads per inch). This is a common size of many fittings on the market. This cap screws 1/2" into the tube for a very secure grip. Our fittings & fast attaches fit nicely into this attachment cap. Adds ¼” to tube length.
  • Solid End Cap: with center divot. 18mm (3/4”) super-thick aluminum. 6061-T6 anodized black. Center divot will assist when drilling the end cap for a drain fitting. Cap screws ½” into tube for excellent hold under pressure. Adds ¼” to tube length.
  • Cups are not included, but this tube will hold 6 black slide cups (we suggest 5 black slide cups and 5 springs for headspace).
