Integrated Brass Live Swivel
The SG28 features an integrated brass live swivel, helping reduce hose twisting while you wash. It makes the whole setup feel smoother in the hand, especially if you’re moving around the car or working with a longer pressure washer hose.

Quick Connect Ready
This kit includes quick connect fittings, making it much easier to swap between your short lance, foam cannon, nozzles, or other pressure washer accessories. No constant threading on and off, just click in what you need and keep washing.

Aquatouch Quick Connect Short Lance
The included Aquatouch Short Lance adds a practical amount of reach without making the setup feel awkward or oversized. It’s ideal for general rinsing, tighter sections, and keeping better control around delicate areas.

Adaptor Kit Included
Each kit includes the selected short gun fitting kit to suit your pressure washer setup. Just make sure you choose the correct adaptor for your machine, as the hose connection is the bit that matters most when getting a short gun upgrade right.

Frequently Asked Questions
Benefits of a short lance
A short lance improves control, comfort and manoeuvrability compared to the longer factory lances supplied with most pressure washers. The more compact setup makes it easier to work around wheels, grilles, mirrors, badges and lower sections of the vehicle without constantly dealing with awkward angles or excessive length.
It can also help reduce wrist and arm fatigue during longer washes, especially when using a foam cannon or rinsing larger vehicles. Combined with quick connect fittings and an integrated nozzle holder, the setup becomes much more practical for day-to-day use, keeping your nozzles organised, easy to access and quicker to swap between while washing.
Do I need any adaptors or fittings to install an MTM short gun?
Often, yes. Most premium aftermarket short guns are designed around a standardised quick connect system, making it easy to attach accessories like foam cannons, lances and nozzles.
Many pressure washers, however, use proprietary hose connections, so you may need a specific adaptor to connect the short gun to your hose and/or machine. Once the correct adaptor is fitted, the setup becomes far more versatile, easier to use and allows you to swap accessories quickly using the quick connect system.
What nozzle is best for vehicles?
For car detailing, a 40° pressure washer nozzle is usually the safest and most versatile choice. It produces a wider spray pattern that distributes pressure more evenly across the surface, making it ideal for rinsing paintwork, wheels, trims and other sensitive exterior areas without being too aggressive.
A 25° nozzle can also be useful for heavier cleaning tasks like tyres, wheel arches, engine bays or stubborn grime. However, it should be used with a bit more caution around softer surfaces and at closer distances.
MTM Short Gun Vs Standard Guns
MTM pressure washer short guns are widely considered a professional-grade upgrade over the standard plastic trigger guns commonly supplied with many pressure washers.
- MTM short guns are constructed using high quality materials, featuring nickel-plated brass internals and stainless steel fittings.
- These materials offer excellent durability and chemical resistance, while also giving the gun a more solid and balanced feel in the hand.
- The upgraded construction allows them to handle higher pressures more reliably, improve longevity with regular use, and provide a more precise and comfortable washing experience.
Overall, MTM short guns are a durable upgrade that can noticeably improve both the usability and performance of your pressure washer setup.
