How does an inflatable anal plug with a detachable hose work? You insert the plug while it is deflated and slim, then squeeze a hand bulb to push air into it. The plug swells inside the body, so the stretch happens past the entrance instead of at it. On most inflatable plugs the hose and bulb stay attached. This one joins the hose to the plug with a magnetic coupling. A valve inside the plug keeps the air in, so you can pull the hose away and the plug stays at the size you set.
Ass Expander: pump it up, then drop the hose
The Ass Expander is an inflatable anal plug that starts at 1.5 inches across and pumps up to as much as 3.9 inches with a hand-squeeze bulb. As it fills, its insertable length grows too, from 4.2 inches to 6.3 inches. An internal pressure valve holds the plug at whatever size you stop at until you release it by hand.
The inflation hose attaches magnetically and comes away with one straight pull, which leaves no tube trailing while the plug is worn. Inside the plug is a weighted ball that shifts as you move. The outer body is phthalate-free silicone over carbon steel internal parts.
Best for: People working toward larger anal stretches who want to set the size themselves, one squeeze at a time. The 1.5 inch starting size and 3.9 inch maximum make it a toy for those with anal experience, not a first plug.

How to use
Before first use, connect the hose, pump the plug up in your hand and practice releasing the pressure valve so you know how it deflates. Let the air out fully. Apply plenty of water-based lubricant to the plug and to yourself, then insert it slowly. Squeeze the bulb once or twice and wait a minute before adding more. Stop well before the stretch becomes painful. Pull the hose straight off at the magnetic coupling if you want to move freely. Always release the valve and deflate the plug completely before you take it out. Never remove it inflated.
Care
- Use water-based lubricant only.
- Wash with warm water and toy cleaner after each use, keeping water out of the hose connection.
- Pat dry. Do not boil it or put it in a dishwasher, since it has a valve and steel parts inside.
- Store deflated in a cool, dry place away from direct sunlight.
- Keep it separated from other toys.

Frequently asked questions
How big does it get?
Deflated, it is 1.5 inches at its widest with 4.2 inches of insertable length. Fully inflated, it reaches 3.9 inches wide and 6.3 inches long. You can stop anywhere in between, and the valve holds that size.
Does it stay inflated without the hose?
Yes. An internal pressure valve holds the air in after the hose is pulled off at the magnetic coupling. The plug stays at the diameter you set until you release the valve by hand.
Is it suitable for beginners?
Not as a first anal toy. The starting width of 1.5 inches is already a medium plug, and the maximum of 3.9 inches is very large. It is intended for people who have used plugs before and want to stretch further in small steps.
How is it different from the Ass Lock plug?
Ass Expander starts slimmer at 1.5 inches and goes larger, up to 3.9 inches, with a weighted ball inside. Ass Lock starts at 2 inches, tops out at 3.3 inches, is shorter, and has textured ridges and a flared anchor base for wear during movement.
What lubricant should I use?
Water-based lubricant only, as the maker instructs. Apply a generous amount before insertion and add more to the base of the plug before removal. Silicone lubricant can damage the silicone surface.
