Pump Donut Seal - NS Novelties Universal Donut Original Clear

A pump sleeve replacement that actually fits: the pump donut from NS Novelties is a flat, disc-shaped TPE/TPR ring designed to create a secure seal around a 2.5-inch penis pump cylinder opening. Transparent, stretchy and waterproof, it does a quiet but essential job.

The Details

• Elastic TPE/TPR construction gives the ring enough flex to seat firmly against the skin without pinching, maintaining an even seal during use.
• Compatible with all lubricant types, water-based, silicone or oil-based, so you can use whatever is already in your kit without worrying about material damage.
• Waterproof throughout, which means rinsing it clean under the tap takes seconds and leaves no residue behind.
• Transparent color makes it easy to inspect the seal and confirm correct placement before you start.

Who It's For

Anyone using a standard 2.5-inch pump cylinder who needs a replacement seal or simply wants a spare on hand. The universal fit means it works across most cylinders of that diameter, not just NS Novelties models. If your current donut has lost its elasticity and the pump is no longer holding suction, this is the straightforward fix.

Usage and Care

Apply a thin layer of your preferred lubricant around the ring before use to improve the seal and comfort. After each session, rinse with warm water and mild soap, then let it air dry completely before storing.
