Description
Please note,
* Using water pressure to remove dents from a 2 two stroke expansion chamber can be effective but it is not an exact science. A two stroke expansion chamber is designed and manufactured to be exactly that, it is not designed to be filled with pressurised water. This kit is intended to make it easier for someone who wants to use water pressure to straighten an exhaust/two stroke expansion chamber.
* Water pressure will always try to push a pipe into a round shape, if any part of an exhaust is not round water pressure may push the exhaust out of alignment. For example; with the 2020 onwards KTM/ Husqvarna ribbed pipes, water pressure may try to push them out of alignment.
The Hydraforce blow out kit is a precision engineered tool, designed to seal each end of your exhaust under pressure. It is machined in the UK from brass, aluminium and carbon steel. The kit is intended to be used with a hand pressure test pump (A tool a plumber would use to test pipework).
Pump Guide
We recommend a pump rated at approximately 40 bar (580 psi approx). Our kits come with an M14 male connection and will include a male 1/2 inch BSP (also known as R 1/2 inch) adapter. Some pumps come with a male 1/2 inch bush that can be unscrewed from the flexible hose to leave a female M14 connection that will suit our male M14 fitting (this is often pumps made in china).
If you have any queries about the suitability of pumps please feel free to email us with a link.
Please find below pumps that have been recommended by our customers, we will add more in due course.

This tool should only be used by a competent person and they do so at their own risk, keep children away whilst this tool is in use.

IT IS VERY IMPORTANT TO MAKE SURE ALL THE AIR IS REMOVED FROM THE SYSTEM PLEASE WATCH THE “HOW TO USE” VIDEO
Compressed air is like a compressed spring, when it is released things can fly off at high speed. You can not compress water so it is safe providing all the air is removed from the system.
