FAQ Femco

LB and SB denote the size of drain hose compatible with a Femco drain plug.

  • SB stands for “small bore”. Femco’s small bore drain plugs use a drain hose with a ½” (12mm) internal diameter. This is a great option for drain plugs from 12mm to 22mm in diameter.
  • LB stands for “large bore”. Femco’s large bore drain plugs use a drain hose with a ¾” (19mm) internal diameter. These are available for plugs as small as 12mm and are the only option available for drain plugs greater than 22mm in diameter. If you have a mixed fleet, requiring a wide range of thread sizes, LB will provide you the largest variety of options.

Drain plugs labeled LB are only compatible with drainers and accessories labeled LB. Likewise, drain plugs labeled SB, are only compatible with drainers and accessories labeled as SB. Don’t forget, the drain plug series must match the drainers and accessories as well! If you’re unsure, please check our compatibility guide below:
