For the last time, you don't have to waste your time with a special hop sleeve from Prometheus or Modify that's going to:
1) cost you $15 (actually $20 if you factor in tax and shipping)
2) potentially have an airleak because the rubber is not matched to your nozzle/hop chamber
Just flip your existing one inside out, shave the nub off that and use it.
