Blue roof flow restrictor (bitumen)

The SR-HM blue roof flow restrictor is designed to be used in conjunction with a standard Bauder hot melt blue roof vertical outlet DN70. The Flow Restrictor is comprised of four parts; baseplate, overflow pipe, baseplate inner and baseplate outer seal. The polyamide baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE overflow slots into the central hole of the baseplate with an inner EPDM seal preventing any leaks. 

Baseplate has a number (0-12) of 10mm restrictive flow holes bespoke to the project.
