Both high-pressure hose families for water jetting units on one page: rubber hoses with 1000 bar, ½" 1100 bar and 1250 bar options, and thermoplastic hoses from 690 to 4000 bar including the DN8 3000 bar hose. For the hose ends see our high-pressure fittings.

Rubber Hoses – 1000 bar, 1100 bar and 1250 bar Hose

Rubber high-pressure hoses connect the pump unit to the gun, lance or tool in water jetting work. The range covers working pressures from 500 to 1450 bar, with inner diameters from DN6 to DN25 and outer diameters from 17.6 to 41.2 mm.

The most requested sizes are the 1000 bar hose (¼"), the ½" 1100 bar hose and the 1250 bar hose (¼" and ⅜"). All sizes are listed in the table below.
