Karcher Pro Adapter 8 TR20IG-M18AG Easy!Lock Lance to Old Brushes, Nozzles and Surface Cleaners

Upgraded your lance but kept the old attachments? The Karcher Pro Adapter 8 TR20IG-M18AG is a compact fitting that links an Easy!Lock lance to older Karcher Professional accessories.

It covers brushes, nozzles and surface cleaners that pre-date the Easy!Lock system. The thread layout is TR20 internal to M18 external. It is small enough to leave on the accessory between jobs.

A new lance does not mean a new accessory set. Fit this and you protect what you already own. It also avoids compatibility problems when you mix older and newer Karcher Professional parts on one site.

Cleaning professionals and contractors with a drawer full of older attachments will see the value. It is built for Karcher Professional pressure washer systems and sits under the Karcher Pro manufacturer warranty. Check your accessory thread before buying. Wondering about the opposite case? That is Adapter 7, which fits an old lance to Easy!Lock nozzles. Adapter 8 handles the lance to old brush route instead. Pick the one that matches your gear. Fitting is a quick screw-on job. No tools are mentioned on the listing.

TR20 is the thread type on Easy!Lock lances at 20mm. M18 is the metric thread at 18mm used on older Karcher Professional accessories. The adaptor has a TR20 internal thread facing the lance and an M18 external thread facing the accessory. In practice you screw it on and the old brush or nozzle clicks into place like it always did.

Switch off the washer and release trapped pressure before changing any accessory. Check the thread for damage before each fit. Tighten by hand until fully seated so nothing flies off under pressure. Do not point the lance at people or animals. Wear eye protection and sturdy shoes.
