Performance Silicone Pump Sleeve Cylinder Liner

This sleeve fits standard pump cylinders with a 2 to 2.5-inch diameter range. The flexible silicone stretches to accommodate different sizes within that range without pinching or losing its seal.

The silicone creates an airtight seal that prevents pressure loss during use. No more frustrating air leaks that kill your suction halfway through a session.

While the silicone is body-safe and easy to clean, we recommend individual use for hygiene. If sharing, wash thoroughly between users or consider getting one for each person.

With proper care, a quality silicone sleeve like this can last for years. Check regularly for small tears or thinning areas and replace when you notice wear to maintain that perfect seal.

Absolutely. The smooth silicone and reliable seal make it much easier for newcomers to achieve and maintain pressure without the learning curve of fighting leaky seals.

A small amount of water-based lube can make application smoother and more comfortable, especially if you have sensitive skin. Just avoid getting lube on the sealing surfaces.

Silicone stays flexible over time, creates superior seals, and is completely body-safe. Unlike cheaper materials, it won't degrade or become sticky with regular cleaning.
