This universal 18 mm pump nozzle adapter is a must-have accessory for anyone using inflatable boats or air mattresses. The standard Ø18 mm size is compatible with most valves used in inflatable dinghies, air beds, and pools – for example, the widely used Boston valve. The nozzle attaches easily to your pump’s flexible hose (either by a friction fit or clamp, depending on your pump model) and allows you to connect the pump securely to the valve of your inflatable item.
Made of high-quality ABS plastic, this adapter is resistant to pressure and wear, so you can rely on it for repeated inflation jobs. It has no moving parts that can break – just a solid nozzle ready to do its job. It creates a tight seal with the valve, meaning you’ll achieve the desired pressure faster and with less effort, as no air is leaking out. If your original pump tip is lost or broken, this product is the perfect replacement that saves you from buying a whole new pump. Its small size means you can always keep it handy – in your boat’s repair kit or even in your pocket.
- Suitable for Boats & More: The nozzle fits the valves of most inflatable boats, tubes, and kayaks. It also works with valves on camping air mattresses, inflatable sofas, swimming pools and more – one simple part, many uses
- Essential Spare Accessory: It’s recommended to have at least one spare nozzle like this, especially on longer trips or camping – if the original gets lost, you’ll still be able to inflate your gear without issues
- Easy to Use: Requires no special skills – attach it to your pump’s hose (most hoses with ~18 mm inner diameter will grip it firmly) and insert the nozzle into the valve opening. It will stay snugly in place while you pump
- Compact: Its small, simple shape makes it easy to store. You can keep it attached to the pump’s hose itself (so it doesn’t get misplaced) or in a small accessories pouch
- Multi-Pump Compatibility: Whether your pump is a foot bellows, a double-action hand pump or an electric inflator – this nozzle is universal and will work, as long as the hose end is a standard size
