🔧 Stihl & Gerni Twist Lock Adapter – Convert to Universal Quick Release

Want to use a Foam Cannon and start making thick snow foam, but your Stihl waterblaster has a special rounded twist lock connection instead of a universal quick release? We’ve got you covered.

Compatibility & Fitment

• Stihl Models: Some Stihl units have different fittings, so please check the product photos carefully to ensure this adapter matches your trigger connection before ordering.

• Connection Options:

  1. Attach to the output end of the trigger piece

  2. Replace the trigger piece and connect directly to the hose

• This adapter connects to the existing Stihl trigger piece and converts it into a ¼‑inch standard quick release, the same fitting used on most foam cannons and detailing accessories.

Compatible with:

• RockCar Stealth Foam Cannon

• Chemical Guys Big Mouth Foam Cannon

• Other universal foam cannons and accessories

This Adapter is to connect as indicated here:

This adapter has the same fitting as shown in the photo (circled to the right) and is designed to connect directly into the end of the Stihl trigger section.

Please check that your Stihl has a fitting like the photo below — if it matches, this adapter will fit.

The Adapter is high quality solid brass. 

The adapter is made from high‑quality solid brass for durability and long life.

Gerni waterblasters also use the same fittings, so if you have a Gerni this adapter should fit as well.

This adapter clicks securely into your Stihl or Gerni twist lock on their waterblasters. It features round lugs for a precise fit.

It converts your Stihl or Gerni into a universal quick release system, just like the larger models, allowing you to connect premium accessories such as Chemical Guys Foam Cannons and the RockCar Stealth Foam Cannon.

The adapter is easy to remove, so you can continue using your existing Stihl or Gerni accessories without hassle.

You can also unhook it from the foam cannon to connect any other accessories that use the standard universal quick release.
