We’ve already taken a deep dive into the 3.5-inch Suction Cup Adapter, but now it’s time to talk about its bigger

and bolder sibling: the 5-inch upgraded version. Hismith, along with its partnered brands, knows their

premium sex machines are at the heart of countless collections. But let’s be real—many of us have personal

favorites that aren’t in their catalog, and sometimes, those favorites are big. Like, seriously big. That’s where

this upgraded adapter comes in. It bridges the gap, letting you pair any suction-cupped toy (up to 5

inches in diameter) with your KlicLok machine, and it’s built to handle even your heftiest playthings with

ease.

​

Design and Material

The 5-inch Suction Cup Adapter is a noticeable upgrade in both size and functionality. Made from sturdy ABS, the adapter has a smooth, sleek surface that mimics the polished look of its metal predecessor. Surrounding the face, a raised lip creates a tight seal for suction-based toys, while a stainless-steel stem locks securely into the KlicLok system.

​

What makes this adapter stand out are the thoughtful additions on the back. Reinforcement structures and a deep securing groove make it ideal for heavier toys. The included elastic straps allow you to secure your toy firmly to the adapter, anchoring it to the back of the plate from two sides; ensuring nothing moves, no matter how intense things get. Bonus: it’s available in both 3.5-inch and 5-inch sizes on Amazon, so you can choose what works best for your collection.

​

Purpose and Functionality

The purpose of the 5-inch Suction Cup Adapter is refreshingly straightforward: to allow users to connect suction-based sex toys to Hismith’s KlicLok machines. This upgraded version enhances the experience further by ensuring that even the largest and heaviest toys stay securely in place. It’s an elegant solution that transforms manual toys into machine-compatible options, breathing new life into existing favorites.

​

Using the adapter is intuitive. Simply press the toy’s suction cup firmly against the adapter’s plate to create a vacuum seal. For added security, slide one of the included elastics down the toy’s shaft and stretch it around the plate until it locks into the groove on the back. Repeat this on the other side with the second elastic and you're all set. The result is a rock-solid connection that holds firm, even during the most vigorous sessions. When you’re done, detaching the toy is just as easy, making this adapter both user-friendly and highly effective.

​

Performance

during testing, given this is an upgraded version; the 5-inch adapter performed as expected. The suction held steady across a variety of toys, regardless of their size, thanks to the dual-anchor system combining suction and elastic straps. Even under the intense thrusts of the Hismith machine, and the weight of the toy; the connection remained secure, with no signs of slipping or loosening. The added elastics proved invaluable for supporting larger toys, preventing any wobbling or instability.

​​

Final Thoughts

If you’re looking to elevate your Hismith experience, the Upgraded 5-inch Suction Cup Adapter is an absolute must-have. It’s sturdy, reliable, and incredibly user-friendly, with thoughtful design features that make it perfect for handling larger toys. Whether you’re experimenting with new additions to your collection or revisiting old favorites, this adapter gives you the freedom to explore and the confidence that everything will stay exactly where it should.

​

For anyone with a Hismith machine and a taste for variety (or size), this adapter is a no-brainer. It’s not just an upgrade—it’s an essential tool for taking your pleasure to the next level. Highly recommend!
