Replacement thumb-clamp found on the Urocare straight-thru adapter with thumb clamp (6005) and white-rubber or/silicone elastomer tubing (6018). Provides an easy on/off flow control/closure. It allows either a free-flow (on) or complete restriction (off) of fluids passing through latex, silicone or white-rubber tubing 0.38 in OD or less. It is not recommended for clear vinyl tubing as this type of tubing tends to be more rigid and may not hold.
