Full Description

This adapter is designed for customers who want to upgrade from standard Karcher foam accessories and use a higher-performing aftermarket snow foam lance. It features a durable engineering-grade polymer body with a precision-machined brass threaded insert, giving a secure, leak-resistant connection while remaining lightweight, corrosion resistant and suitable for regular detailing use.

Many aftermarket snow foam lances are supplied with a quick release fitting already installed. Before fitting this adapter, simply unscrew and remove the existing fitting from the top of the snow foam bottle or lance, then install this Karcher adapter in its place.

Why Choose This Adapter?

Aftermarket snow foam lances often provide thicker foam, better chemical control and improved pre-wash performance compared with many standard foam attachments.

The polymer body keeps the fitting lightweight, while the brass threaded insert provides strength where it matters most. This makes it a practical upgrade for home users, enthusiasts and professional detailers who want better foam performance from their Karcher pressure washer.

How To Install

  1. Remove the existing quick release fitting from your aftermarket snow foam lance if one is already installed.
  2. Wrap the brass thread of this adapter with PTFE, also known as plumber's tape, before installation.

  5. Connect the completed snow foam lance to your Karcher K2, K3, K4, K5, K6 or K7 pressure washer.
