MKHS700. Backflow Testing Hoses. The only hoses specially made for backflow testing.

If you're not using our hoses, your hose filter is probably leaking right now.  We listened to testers in the field and went with all brass construction on our filter housing and a double O-ring seal to stop those leaks.

Backflow assemblies are often in tight spaces.  Our hoses are a little more flexible than other hoses, particularly in cold weather!

These hoses have a wide fitting and finer knurling pattern so that you can get them on and off the test kit and the assembly easier without tearing up your hands.

If you're not using our hoses, then your hoses are probably designed to move refrigerant and not made from potable water safe materials.  Our hoses are made from NSF food safe materials and are specifically designed for backflow testers. 

These hoses are the ones that are included with the Mako test kit.
