Hop Filter / Sieve with Seal for 3/4BSP Cask Nut & Tail (Top Hat)

For use with 3/4BSP cask nut & tail connections.
A Hop Filter is a valuable item used to seal the cask nut & tail connector to your cask tap, extractor rod or Flextractor system.   This dual-purpose seal also helps filter out any sediment from being pulling into the dispense system causing equipment further up the line to become blocked and/or failing to seal.
