DRAIN-O flow-thru plug liquid platinum silicone

DRAIN-O flow-thru plugs are designed for max-stretch, no matter the size you choose. Each plug is designed with special features that help keep DRAIN-O in place.

DRAIN-O has a pencil-thick airhole vent through the center of the plug—the design helps “equalize” the pressure inside and out. That feeling you get when you want a plug to stay put but your muscles want to expel it is partly built-up pressure behind the plug—this feature helps with that.

DRAIN-O has an innovative shape designed for max gape-keeping: there is a “double seal” with one flare at the tip of the conehead and a fat rubbery second lip halfway to the base. The gap between the two allows you to morph to the shape with more surface to grip.

We added subtle indentations around the middle that channels lube and air front to back and help the plug to stay centered and keeps twisting to a minimum.

This plug has a serious mission to fill you and keep you filled.

DRAIN-O is also available in our new RECYCLER piss-play toys…with better fit, a better wet seal, and more long-use comfort.

DRAIN-O is handcrafted in Los Angeles using the absolute best Liquid Platinum Silicone. We custom mix our silicone for every batch of toys we make by hand, it’s the only way to get the exact right feel for every design…you just can’t achieve this with machine made gear. Our goal is the absolute best design and feel for every Platinum Silicone toy we make.
