Full Description

Better Detailing Karcher K2-K7 to Aftermarket Snow Foam Lance Adapter allows you to connect compatible aftermarket snow foam lances directly to Karcher K2, K3, K4, K5, K6 and K7 pressure washers.

This adapter is designed for customers who want to move on from the standard Karcher foam accessories and use an 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. This Better Detailing adapter allows compatible Karcher K-Series pressure washers to connect to many aftermarket foam lances quickly and securely.

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 to run an aftermarket foam lance on 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.
  3. Screw the adapter securely into the snow foam bottle or lance.
  4. Tighten until secure, but do not overtighten.
  5. Connect the completed snow foam lance to your Karcher K2, K3, K4, K5, K6 or K7 pressure washer.

It suits home users, enthusiasts and professional detailers upgrading their pre-wash. Pair it with an aftermarket snow foam lance and a dedicated snow foam.

Better Detailing fittings and brushes

Snow foam lance adapters. Each adapter replaces the machine fitting on an aftermarket snow foam lance, so the lance fits your pressure washer. The Karcher K2 to K7 adapter has an engineering-grade polymer body with a precision-machined brass thread. The range also covers Karcher Pro HD and HDS, new type, Karcher Pro HD and HDS, old type, Nilfisk, Gerni, Kew, Alto, Stihl and Husqvarna, Bosch AQT short type and Portland Husky, Silverline, Hunter, Anlu, IPC and Skil 0761 and Lavor, Parkside, Vax, Sterwins and Argos Qualcast.

Stubby guns and fittings. The High Pressure Stubby Trigger Gun has an M22 male inlet and a 1/4in quick release outlet. To fit a stubby gun to your machine there are adapters for Karcher, Nilfisk and Lavor, Lutian and Black & Decker. The solid brass M22 male to 3/8in female quick release adapter and 1/4in BSP female to 1/4in quick connect adapter convert threads to quick release, and the brass M22 14mm swivel connector turns a full 360 degrees between gun and hose so the hose stops twisting as you walk round the car. Check your thread first: it is made for M22 14mm fittings.

Nozzles and sprayers. The Quick Release Nozzle Set has four stainless steel tips: 0 degree red, 15 degree yellow, 25 degree green and 40 degree white. The wider the angle, the gentler the spray, so the 40 degree tip is the one for rinsing paintwork. The Trigger Spray Head fits 28/410 bottle necks and gives about 1.2ml per full pull.

Detailing brushes. The natural boar hair brushes come as the Sash Brush in small, medium and large, the Premium Boar Hair Brush in six sizes, the V2 Boar Hair Brush in five sizes with a chemical-resistant handle and hanging loop, and the Plastic Handle Boar Hair Brush. They are soft enough for vents, badges, gloss black trim and leather. The ultra-soft synthetic brushes come long and short, the Firm Synthetic Brush has firm bristles with soft flagged tips for panel gaps, engine bays, calipers and polish residue, and the Chemical Resistant Brush stands up to repeated use with strong wheel cleaners.

Shop the range by type: adapters and quick connects, snow foam lances, stubby trigger guns and detailing brushes.

Which snow foam lance adapter do I need?

Most aftermarket snow foam lances come with one machine fitting. If your pressure washer takes a different one, an adapter swaps it, so match the adapter to the brand of your machine:

If you are not sure which connection your machine has, check its manual or the gun outlet, or ask our team in the Ilkeston shop for help choosing a compatible adapter. For lances to go with the adapter, see our snow foam lances.
