Have an S&B Helmet Particle Separator and want to use Maglock Air? Then this is the adapter for you! While the MagLock Air fits any standard 1.25in hose, the S&B hose is cumbersome, bulky and too large for the MagLock Air to fit. Simply remove your existing hose, slip on the adapter, tighten the hose clamp and you're done! Your S&B Separator is now ready for MagLock Air! Comes with S&B adapter with 6 feet of our Air hose pre-installed.
